Aortic Aneurysm Repair

What this procedure is

An aortic aneurysm repair is a procedure used to strengthen a weak, bulging section of the aorta. The aorta is the body's main artery, which carries oxygen-rich blood from the heart to the rest of the body.

There are two primary ways your clinician may perform this repair:

• Open Surgery: The surgeon makes an incision to reach the aorta and replaces the weakened section with a graft, which is a tube made of durable man-made fabric.
• Endovascular Repair: This is a less-invasive method where a clinician uses small tubes called catheters to place a stent-graft (a fabric-covered metal mesh tube) inside the aorta to reinforce the wall from the inside.

What it treats or fixes

This procedure treats an aortic aneurysm. An aneurysm is a bulge that forms when the wall of the aorta becomes weak or thin. Because the aorta is under constant pressure from blood flow, this bulge can grow over time.

The main goal of the repair is to prevent the aneurysm from leaking or growing larger. By reinforcing the aorta with a graft or stent-graft, the procedure allows blood to flow through the vessel without putting pressure on the weakened area.

Your clinician may recommend this treatment if the aneurysm has reached a certain size or if it is changing quickly. Fixing the bulge helps ensure the aorta remains strong and stable.

How common it is & where it's done

Aortic aneurysm repair is a common and standard medical procedure. It is performed regularly in hospitals throughout the United States and Canada by specialized surgical teams, including vascular and cardiothoracic surgeons.

The procedure is typically done in a hospital operating room. In some cases, it may be performed in a "hybrid" room, which combines a traditional operating room with advanced X-ray imaging to help guide the clinician during the repair.

Because this is a major procedure, it is performed in a controlled hospital environment where a dedicated care team can monitor your progress. Your clinician will help you understand what to expect based on the specific location of the aneurysm and the type of repair being used.

Recovery: What to Expect

After the procedure, you will likely spend some time in the hospital. If you had a minimally invasive repair (using small incisions), your stay might be shorter than if you had open surgery. Your care team will monitor your heart rate and blood pressure closely during this time.

Once you are home, your clinician may suggest a gradual return to your normal routine. You will likely be asked to avoid heavy lifting or strenuous exercise for several weeks to allow the area to heal. It is important to attend all follow-up appointments. These often include imaging tests, like an ultrasound or CT scan, to make sure the repair is working correctly.

Risks & Possible Complications

Every medical procedure has some risks. Potential complications can include:

• Bleeding or infection at the incision site.
• Blood clots or issues with blood flow to the legs or kidneys.
• An endoleak, which is when blood flows around the graft (the artificial tube used to reinforce the aorta).

Your surgical team takes many steps to prevent these issues. You should contact your clinician if you notice signs of infection, such as redness or warmth at the incision, a fever, or sudden pain that does not go away with rest.

Outcomes & Long-Term Results

Aortic aneurysm repair is generally very successful at preventing the aneurysm from growing or bursting. Most people return to their regular activities and enjoy a good quality of life after they have fully recovered.

Long-term success depends on regular monitoring. Because the aorta can change over time, your doctor will likely schedule periodic scans to ensure the graft remains stable and secure. Managing other health factors, such as blood pressure and cholesterol, can also help maintain the health of your blood vessels over the long term.

Emotional Support & Reassurance

It is natural to feel some anxiety when preparing for or recovering from a major procedure. Many patients find comfort in speaking with their healthcare team about what to expect at each step. These procedures are common and performed by specialized teams dedicated to your safety.

Taking things one day at a time can help you feel more in control of your recovery. If you feel overwhelmed, your clinician may be able to connect you with support groups or resources to help you and your family navigate the emotional side of your health journey.

Why doctors recommend it

The aorta is the largest blood vessel in your body. It acts like a main highway, carrying oxygen-rich blood from your heart to the rest of your organs. An aortic aneurysm is a bulge or weak spot that develops in the wall of this vessel. Over time, the pressure of blood flowing through the aorta can cause this bulge to grow larger and the wall to become thinner.

Your clinician may recommend repair if they believe the aneurysm is at risk of leaking or bursting. They often look at specific factors to make this decision, such as:

• Size: If the aneurysm reaches a certain width (often around 5 to 5.5 centimeters), the risk of it opening up increases.
• Growth rate: If imaging tests show the bulge is growing quickly over a short period of time.
• Symptoms: If you experience persistent pain in the chest, back, or abdomen that may be caused by the aneurysm pressing on other parts of the body.

Urgent vs planned treatment

Most aortic aneurysm repairs are planned (elective) procedures. This means the aneurysm was found during a routine check-up or a scan for another issue. A planned surgery gives your medical team time to run tests, check your heart health, and decide whether a traditional open surgery or a less invasive endovascular repair (using a small tube called a stent) is the best fit for your needs.

In some cases, treatment becomes urgent or an emergency. This happens if the aneurysm begins to leak or suddenly bursts. Emergency surgery is performed immediately to stop internal bleeding and repair the damaged section of the aorta. While planned surgery is generally preferred because it allows for more preparation, modern medical techniques allow clinicians to act quickly in these critical situations.

Goals of treatment

The main goal of this procedure is to prevent a life-threatening rupture. By reinforcing the weak section of the aorta, the surgery ensures that blood can flow through the vessel without putting dangerous pressure on the thin walls of the aneurysm.

During the repair, a clinician typically uses a graft. This is a durable, man-made tube that replaces or lines the weakened part of the artery. The specific goals of this treatment include:

• Strengthening the aorta: Providing a new, sturdy path for blood flow that bypasses the weak spot.
• Relieving pressure: Stopping the aneurysm from pushing against nearby nerves or organs, which can help reduce or eliminate pain.
• Improving long-term safety: Reducing the risk of a future emergency so you can return to your daily activities with more confidence.

Who may benefit

An aortic aneurysm is a bulge or weak spot in the wall of the aorta, which is the body's main artery. Your clinician may recommend repair if the aneurysm reaches a specific size—often around 5 to 5.5 centimeters—or if it is growing quickly over a short period. The goal of the procedure is to strengthen the artery and prevent it from leaking or bursting.

Some people may benefit from surgery even if the aneurysm is smaller. This often includes individuals with a family history of the condition or those with certain genetic factors that affect the strength of their blood vessels. If you are experiencing symptoms like persistent pain in the chest, back, or abdomen, your care team may suggest repair to protect your health.

When it may not be the right option

Surgery is not always the first step. If an aneurysm is small and not causing symptoms, your clinician may suggest "watchful waiting." This involves regular imaging tests, such as ultrasounds or CT scans, to monitor the size of the bulge. During this time, they may focus on managing your blood pressure and cholesterol to keep the artery stable.

In some cases, the risks of surgery may outweigh the benefits. This is more common if a person has other serious health conditions, such as advanced heart, lung, or kidney disease. Your care team will look at your overall health and the stability of the aneurysm to decide if a procedure is the safest choice for you at this time.

Questions to ask your care team

It is helpful to bring a list of questions to your appointments to better understand your options. You might consider asking:

• How large is my aneurysm, and has it changed since my last scan?
• What are the risks of having the surgery compared to the risks of waiting?
• Am I a candidate for a minimally invasive repair, or would I need an open surgery?
• What lifestyle changes can I make to help manage my heart health?
• What does the recovery process look like for someone with my health history?

In the procedure room

When you arrive, you will be greeted by a team of specialists, including surgeons, nurses, and anesthesiologists. The room is kept cool and is filled with specialized equipment, such as monitors and imaging screens that help the team see your heart and blood vessels in detail. You will be helped onto a comfortable, padded procedure table where the team will prepare you for the surgery.

High-level steps

There are two main ways your clinician may repair an aneurysm. In an open repair, the surgeon makes an incision to reach the aorta (the body’s main artery) and replaces the weakened section with a man-made tube called a graft. This graft is sewn into place to act as a new, strong path for blood flow. In some complex cases, the clinician may use medical packing or leave the incision site temporarily open to manage swelling and ensure the area is stable before final closure.

In an endovascular repair, the surgeon makes much smaller cuts, usually in the groin area. They use thin, flexible tubes to slide a stent-graft (a fabric tube supported by a metal mesh) through your blood vessels until it reaches the aneurysm. This reinforces the artery from the inside, which helps prevent the weakened area from bulging or leaking.

Anesthesia and pain control

For an open surgery, you will typically receive general anesthesia. This means you will be in a deep sleep and will not feel any pain during the procedure. For an endovascular repair, your team may use local anesthesia to numb the area along with medicine to help you relax, or they may choose general anesthesia depending on your needs.

After the procedure, your care team will focus on keeping you comfortable. Pain is often managed with intravenous (IV) medicine or other specialized methods, such as an epidural, to help dull any soreness as you begin to wake up.

Monitoring and safety steps

Throughout the entire process, the medical team uses advanced monitors to track your heart rate, blood pressure, and oxygen levels. This constant check ensures your body remains stable and safe while the surgeons work. If you are under general anesthesia, a breathing tube may be used to support your lungs and ensure you get enough oxygen while you are asleep.

The team also monitors the blood flow to your legs and other organs. These safety steps are vital for making sure the new graft is working correctly and that your circulation remains healthy during the repair.

Immediately after the procedure

Once the repair is finished, you will be moved to a recovery area or an intensive care unit (ICU). You may feel sleepy, thirsty, or have a slightly sore throat if a breathing tube was used. Nurses will check your vital signs frequently and will also check the pulses in your legs to ensure good blood flow.

It is common to feel some numbness or soreness near the incision sites. Your team will encourage you to take deep breaths and, when you are ready, to begin moving around slowly to help your body recover.

Typical procedure length

The time spent in the procedure room can vary based on the type of repair being performed. An endovascular repair is often shorter and may take a few hours. An open repair is more complex and typically takes longer to complete.

Your clinician will provide a more specific estimate of how long your procedure might take based on your individual health and the specific type of repair planned.

Common approaches (open vs minimally invasive)

Doctors generally use one of two main ways to fix an aortic aneurysm. The best choice depends on the size and location of the aneurysm, as well as your overall health and anatomy.

• Open repair: This is the traditional surgery. A surgeon makes an incision (cut) in your chest or abdomen to reach the aorta. The weakened section is replaced with a fabric tube called a graft, which is sewn into place. This creates a strong new path for blood flow. Because this is a major surgery, recovery time is usually longer.
• Endovascular repair: This is a minimally invasive option. Instead of a large incision, the doctor makes small cuts near the groin. They thread thin tubes (catheters) through the blood vessels to reach the aneurysm. A stent graft (a fabric tube supported by a metal frame) is placed inside the aorta to seal off the bulge from the inside. This often allows for a faster recovery, but it is not suitable for every patient.

Partial vs total

The extent of the repair depends on how much of the aorta is affected. In many cases, the surgeon only needs to replace the specific section where the bulge is located. This focuses the repair on the most damaged area while leaving the rest of the vessel alone.

However, if the aneurysm is very large or extends near the heart, a more extensive repair may be needed. For example, if an aneurysm in the chest involves the aortic valve (which controls blood flow out of the heart), your surgeon may replace both the aorta and the valve at the same time. In other cases, they may need to replace a larger portion of the aorta, such as the aortic arch, to ensure the vessel is stable.

Revision or repeat procedures

Most aortic aneurysm repairs are designed to be permanent, but regular check-ups are important to ensure the repair stays strong. This is especially true for endovascular repairs. Sometimes, the stent graft can slip or a small leak may develop around it. If this happens, a follow-up procedure might be needed to fix the seal.

Open repairs are generally very durable and rarely require a second surgery. However, your care team will still monitor your heart and blood vessels over time. If an aneurysm forms in a different part of the aorta later on, or if a previous repair needs adjustment, your doctor will discuss the best options for a revision procedure.

How to prepare for Aortic Aneurysm Repair

Tests and imaging that may be done

Before your procedure, your healthcare team needs to check your overall health and map the shape of the aneurysm. This helps them plan the safest way to repair the aorta.

• Blood and urine tests: These check how well your kidneys and other organs are working.
• Heart tests: An electrocardiogram (ECG) records your heart rhythm. You might also have an echocardiogram (ultrasound of the heart) or a stress test.
• Imaging scans: A CT scan, MRI, or ultrasound is often used to see the exact size and location of the aneurysm.
• Angiogram: In some cases, your doctor may use a special dye and X-rays to look closely at your blood vessels.

Medication adjustments

It is important to tell your clinician about every medicine you take. This includes prescription drugs, over-the-counter pain relievers, vitamins, and herbal supplements. Some of these can increase the risk of bleeding during the repair.

• Blood thinners: If you take medicines like aspirin, warfarin, or other blood thinners, you may be asked to stop them a few days before surgery. Only stop medicines if your clinician instructs you.
• Smoking: If you smoke, your doctor will strongly advise you to stop as soon as possible. Quitting helps improve blood flow and healing after the surgery.

Day-before and day-of instructions

Your healthcare team will give you specific rules to follow as your surgery date gets closer. Following these steps helps ensure the procedure goes smoothly.

• Fasting: You will likely be told not to eat or drink anything after midnight the night before your surgery.
• Hygiene: You may need to shower with a special antibacterial soap the night before or the morning of the procedure to lower the risk of infection.
• Personal items: Leave jewelry, watches, and other valuables at home. You may be asked to remove nail polish, contact lenses, or dentures before going into the operating room.
• Arrival: When you arrive at the hospital, a nurse will help you get ready. They will likely start an intravenous (IV) line in your arm to give you fluids and medicine to help you relax.

General surgical risks

Like any major operation, repairing an aortic aneurysm carries certain risks. Your healthcare team takes many steps to lower these risks before, during, and after your surgery. Factors such as your age, general health, and the type of procedure (open or endovascular) can influence your specific risk level.

Common risks associated with many surgeries include:

• Reactions to anesthesia: Some patients may have breathing difficulties or reactions to the medication used to put them to sleep.
• Bleeding: There is a possibility of blood loss during the procedure, which may require a blood transfusion.
• Infection: This can occur at the incision site or in the lungs (pneumonia) during recovery.
• Blood clots: Clots can form in the legs (deep vein thrombosis) and potentially travel to the lungs. Your care team will likely use special stockings or medication to help prevent this.

Procedure-specific complications

Because the aorta is the main blood vessel supplying the body, the repair process can sometimes affect nearby organs or systems. These complications vary depending on whether the aneurysm is in the chest (thoracic) or abdomen (abdominal).

Possible complications specific to aortic repair may include:

• Heart and brain issues: There is a risk of irregular heartbeats (arrhythmia), heart attack, or stroke, particularly if the aneurysm is located close to the heart.
• Kidney or organ damage: The procedure involves clamping or working near arteries that supply the kidneys and intestines. In some cases, this can lead to temporary or permanent kidney failure or damage to the intestines.
• Graft issues: The synthetic tube (graft) used to repair the aorta can sometimes move out of place, leak blood (called an endoleak), or become infected. This is more common with endovascular repairs than open surgery.
• Nerve or spinal cord injury: In rare cases, the blood supply to the spinal cord may be interrupted, which can lead to loss of sensation or paralysis in the legs.

How complications are treated

Most complications are treatable, especially when detected early through careful monitoring. Your surgical team will watch you closely in the hospital to manage any immediate issues, such as heart rhythm changes or blood pressure fluctuations.

Treatment approaches may include:

• Medication: Antibiotics are used to treat infections, while other medications can help manage heart rate, blood pressure, or kidney function.
• Additional procedures: If a graft leaks or moves, your doctor may recommend a minimally invasive procedure to fix the seal. In some cases, a second surgery may be needed.
• Long-term monitoring: You will likely have regular follow-up appointments and imaging scans (like ultrasounds or CT scans) for the rest of your life. These checks ensure the graft stays in place and the aneurysm does not return.

Pain control medicines

Managing your comfort is a top priority after an aortic aneurysm repair. Your clinician may use a variety of medicines to help you feel better as you heal. In the hospital, you might receive pain relief through an IV (a thin tube placed in a vein) or as a pill. Once you are ready to go home, your care team will likely provide a prescription or suggest over-the-counter options.

Your clinician will tailor this plan based on your health history and the type of repair you had. It is important to tell your team about any allergies you have or other medicines you are taking to avoid interactions. Using these medicines as directed helps you move around more easily, which is an important part of recovery.

Antibiotics

Antibiotics are medicines used to prevent or treat infections caused by bacteria. Because any surgery carries a small risk of infection, your care team will usually give you antibiotics shortly before the procedure begins. This helps protect your body while the repair is being performed.

You may continue to receive these medicines for a brief period after the surgery. Your clinician will determine the right type of antibiotic for you. Be sure to mention if you have ever had an allergic reaction, such as a rash or trouble breathing, to any specific antibiotics in the past.

Blood thinners and clot prevention

During and after your repair, your clinician may use medicines to help prevent blood clots. These are often called blood thinners or anticoagulants. They help keep the blood flowing smoothly through the newly repaired section of your aorta and prevent clots from forming in your legs or lungs.

• Anticoagulants: These medicines slow down the body's process of making clots.
• Antiplatelets: Medicines like aspirin help prevent blood cells from sticking together.

Your clinician will tailor the use of these medicines to your specific risk factors. Because these medicines affect how your blood clots, your team will monitor you closely. Always talk to your doctor before starting or stopping any blood-thinning medicines, as they can interact with other supplements or prescriptions.

Emergency warning signs

While recovery takes time, certain symptoms require immediate attention. These signs may indicate a problem with your heart, lungs, or the repair itself. Call 911 or go to the nearest emergency room if you experience:

• Chest pain or pressure: This includes squeezing pain or sudden, sharp discomfort in the chest.
• Trouble breathing: Severe shortness of breath or difficulty catching your breath.
• Sudden, severe pain: Intense pain in your back, abdomen (belly), or chest that does not go away.
• Coughing up blood: Or coughing up yellow or green mucus.
• Leg changes: If your legs suddenly feel cold, look pale or blue, or become numb.

Call your surgeon or clinic if…

Contact your healthcare team if you notice signs of infection or if your recovery does not seem to be progressing as expected. Your clinician may want to check your incision or adjust your medications. Call if you have:

• Fever or chills: A temperature of 100.4°F (38°C) or higher.
• Incision changes: Increased redness, swelling, bleeding, or drainage (fluid leaking from the cut).
• Worsening pain: Pain that increases or is not relieved by your prescribed pain medicine.
• Digestive issues: Nausea, vomiting, or inability to have a bowel movement.
• Urinary problems: Pain when urinating, bloody urine, or changes in how often you need to go.

Expected vs concerning symptoms

It is helpful to know what is part of the normal healing process and what might be a sign of a complication.

Expected symptoms

Most people feel tired for several weeks after surgery. You may have some soreness, itching, or bruising around the incision site. It is also common to have a smaller appetite or mild constipation, often due to pain medications.

Concerning symptoms

Symptoms that stop you from moving around or getting rest are not typical. Be alert for numbness or tingling in your legs or feet, which could suggest an issue with blood flow. If the area around your incision feels hot to the touch or begins to open up, let your clinician know right away.

Non-surgical treatments

If an aneurysm is small and not causing symptoms, your clinician may suggest managing it without surgery. The main goal is to keep the aneurysm from growing larger by controlling your heart health. This often involves taking medications to lower your blood pressure and cholesterol. High blood pressure can put extra stress on the weakened wall of the aorta (the body's main artery), so keeping it in a healthy range is very important.

Lifestyle changes are also a key part of non-surgical care. Your care team may recommend:

• Quitting smoking: Smoking is a major risk factor for aneurysm growth.
• Healthy diet: Eating foods that support heart health.
• Gentle exercise: Staying active while avoiding heavy lifting that might strain the aorta.

Watchful waiting

Watchful waiting, also known as active surveillance, means your clinician will monitor the aneurysm closely over time. This is common for aneurysms that are small enough that the risk of surgery is higher than the risk of the aneurysm itself. Instead of immediate repair, you will have regular imaging tests to check for any changes.

These tests usually include an ultrasound or a CT scan every 6 to 12 months. These scans allow your doctor to measure the size of the aneurysm and see how fast it is growing. As long as the aneurysm stays small and you do not have symptoms, you may continue with this approach for many years.

When surgery becomes the best option

Your clinician may recommend surgery if the aneurysm reaches a certain size or begins to change quickly. For many people, repair is considered when an abdominal aneurysm reaches about 5 to 5.5 centimeters (roughly 2 inches) in diameter. For an ascending aneurysm (located near the heart), the size threshold may be different based on your specific health history.

Surgery might also be necessary if:

• Rapid growth: The aneurysm grows more than 0.5 centimeters in a six-month period.
• Symptoms: You begin to feel new pain in your chest, back, or abdomen, which could mean the aneurysm is changing.
• Risk of rupture: The risk of the aneurysm leaking or bursting becomes greater than the risks associated with the surgery itself.

The choice between a traditional open surgery or a less invasive procedure, like an endovascular repair (using a fabric-covered tube called a stent-graft), depends on the shape of the aneurysm and your overall health.

Hospital services that commonly perform this surgery

Aortic aneurysm repair is a specialized procedure usually found at hospitals with dedicated heart and vascular centers. Depending on where the aneurysm is located, you may be cared for by a vascular surgery team (specialists in blood vessels) or a cardiothoracic surgery team (specialists in the heart and chest).

These hospitals often have advanced imaging departments that use CT scans or ultrasound to monitor the aneurysm before and after the procedure. They also feature Intensive Care Units (ICU) where patients stay briefly after surgery so that specialized nurses and doctors can monitor their recovery closely.

Patient resources and support services

Many hospitals provide support services to help you prepare for surgery and recover safely at home. Because smoking is a significant risk factor for aneurysms, many centers offer smoking cessation programs to help patients quit before their procedure. Your clinician may also suggest meeting with a dietitian to discuss a heart-healthy diet to protect your blood vessels.

After surgery, you may have access to these resources:

• Physical Therapy: Specialists who help you regain your strength and move safely during your initial recovery.
• Case Management: Staff who help arrange home health care or medical equipment if your clinician determines you need extra help at home.
• Cardiac Rehabilitation: A supervised program of exercise and education designed to improve heart and vessel health.

Questions for choosing where to have surgery

Choosing a hospital is an important step in your care. You may want to ask your surgical team about their experience with both open repair (a traditional surgery) and endovascular repair (a less invasive method using a small fabric tube called a stent). Research suggests that the best results often come from centers that perform these procedures frequently.

Consider using this checklist when choosing a facility:

• How many aortic aneurysm repairs does this hospital and surgical team perform each year?
• Does the hospital offer both open and endovascular (stent-graft) options?
• What kind of follow-up imaging and long-term monitoring does the center provide after the surgery?
• What support services, such as physical therapy or nutrition counseling, are available to help me during my recovery?

Conditions commonly treated by this procedure

Aortic aneurysm repair is primarily used to treat a bulge or weak spot in the aorta, which is the body's main artery. This condition is known as an aortic aneurysm. Depending on where the bulge is located, your clinician may refer to it as an abdominal aortic aneurysm (in the belly area) or a thoracic aortic aneurysm (in the chest area).

• Abdominal Aortic Aneurysm (AAA): This is a common type of aneurysm that occurs in the lower part of the aorta. Repair is often recommended if the bulge reaches a certain size to prevent it from leaking or bursting.
• Ascending Aortic Aneurysm: This occurs in the section of the aorta closest to the heart. It may be treated with surgery to replace the weakened section of the vessel.
• Atherosclerosis: Often called "hardening of the arteries," this condition involves a buildup of fat and cholesterol (plaque) that can weaken the walls of the aorta over time.
• Connective Tissue Disorders: Certain inherited conditions, such as Marfan syndrome, can affect the strength of the blood vessel walls and may lead to the development of an aneurysm.

Related symptoms people search for

In many cases, an aortic aneurysm may not cause any noticeable symptoms. They are often called "silent" because they are frequently found during routine checkups or imaging tests for other health concerns. However, as an aneurysm grows, some people may experience signs that should be evaluated by a clinician.

Commonly reported symptoms that may be associated with an aneurysm include:

• A pulsing sensation in the abdomen, which might feel similar to a heartbeat.
• Deep, steady pain in the abdomen or along the side of the body (the flank).
• Persistent back pain that does not have another clear cause.
• Chest pain or tenderness, which can sometimes occur with aneurysms located in the upper part of the aorta.

Because these symptoms can be related to many different health issues, your clinician may use specialized imaging to determine if an aneurysm is present. Early evaluation is helpful for monitoring the condition and planning any necessary treatment.

Evidence overview

Medical researchers and doctors have studied aortic aneurysm repair for decades to understand the best ways to treat this condition. The primary goal of repair is to prevent the aneurysm from bursting (rupturing). Studies generally compare two main approaches: traditional open surgery and endovascular repair (a less invasive option using a catheter).

Research published in major medical journals, such as the New England Journal of Medicine, suggests that endovascular repair often carries a lower risk of complications immediately after the procedure and allows for a faster recovery time compared to open surgery. However, long-term data indicates that survival rates after a few years are often similar for both methods.

Evidence also shows that while endovascular repair is less invasive, it may require more follow-up appointments and minor procedures later to ensure the graft remains in the correct position and is working properly. Your care team uses this evidence to help decide which method fits your specific needs.

Safety notes and individualized care

Aortic aneurysm repair is a major procedure, and your healthcare team will carefully weigh the benefits against the potential risks. While these surgeries are performed routinely at specialized centers, possible risks can include bleeding, infection, blood clots, or stress on the heart and kidneys. Specific risks may vary depending on whether the aneurysm is in the chest (ascending aorta) or the abdomen.

Because every patient is different, treatment plans are highly individualized. Your clinician will look at several factors before recommending surgery, including:

• Size and growth: Smaller aneurysms are often monitored closely with imaging tests rather than treated with surgery immediately.
• Anatomy: The shape and location of the aneurysm help determine if a minimally invasive repair is possible.
• Overall health: Your age and other medical conditions help determine which type of repair is safest for you.

Before any procedure, your doctor will discuss your specific anatomy and help you understand which approach offers the best balance of safety and long-term success for your situation.
