A ruptured aortic aneurysm is a life-threatening emergency. If you or someone near you has sudden, severe abdominal, back, or chest pain — especially with faintness, dizziness, a rapid pulse, or collapse — call 911 immediately. Do not drive yourself and do not wait to see if it passes.
An abdominal aortic aneurysm (AAA) is often called silent because most people feel nothing until the wall of the aorta becomes dangerously thin. Aortic aneurysm repair is the surgical fix that prevents that wall from rupturing — an event that carries an out-of-hospital mortality above 80 percent, according to the CDC. Two main approaches dominate modern care: minimally invasive endovascular repair (EVAR) and traditional open surgery. Knowing how each works, who qualifies, and what recovery looks like helps you have a clearer conversation with your vascular surgeon. This guide is general information, not medical advice.
What Aortic Aneurysm Repair Is and Who Needs It
An aortic aneurysm is a balloon-like bulge in the aorta, the largest artery in the body. When the bulge grows past a critical size, the wall thins and rupture risk climbs steeply. Repair reinforces or replaces the weakened section before that happens. Aneurysms occur most often in the abdomen (AAA) but also in the chest (thoracic aortic aneurysm), and the two are managed with related but distinct thresholds and techniques.
Most surgeons follow size and growth thresholds like those described by the National Heart, Lung, and Blood Institute: elective repair is commonly considered for abdominal aneurysms about 5.5 cm or larger in men, around 5.0 cm or larger in women, or any aneurysm growing more than roughly 0.5 cm in six months. Symptomatic aneurysms (new back or abdominal pain, tenderness) and ruptured aneurysms are surgical emergencies. Thoracic aortic aneurysms have separate thresholds, often around 5.5–6.0 cm depending on the cause and whether a connective-tissue disorder is present. These numbers are general guides — your surgeon individualizes them to your anatomy and overall health.
Risk factors for AAA include age over 65, smoking (the strongest modifiable risk factor), male sex, family history, high blood pressure, and atherosclerosis. The USPSTF recommends one-time ultrasound screening for men aged 65–75 who have ever smoked (a Grade B recommendation in its 2019 statement), and selective screening for men in that age range who never smoked; it does not recommend routine screening for women who never smoked and found evidence insufficient for women who ever smoked or have a family history. Screening guidance can be updated, so verify current recommendations with your clinician.
How the Procedure Is Performed
Two approaches are widely used. EVAR (endovascular aneurysm repair) is the less invasive option. Through small groin incisions or punctures, the surgeon threads a stent graft up through the femoral arteries and deploys it inside the diseased aorta. Blood then flows through the graft instead of pushing on the weak wall. The procedure is usually done under general or regional anesthesia and takes about two to four hours, per the Cleveland Clinic.
Open AAA repair is the older but still essential option for complex anatomy or younger patients. The surgeon makes a long abdominal or flank incision, clamps the aorta, removes the diseased segment, and sews in a fabric graft. Operating time typically runs three to six hours, with general anesthesia and a planned intensive-care stay afterward. According to the Society for Vascular Surgery, EVAR now accounts for roughly 80 percent of elective AAA repairs in the United States, though open repair remains preferred when the anatomy is unfavorable for a stent graft. Thoracic endovascular aneurysm repair (TEVAR) uses similar endovascular principles for aneurysms in the chest.
Preparation and What to Expect on the Day
Pre-operative workup typically includes a CT angiogram to map the aneurysm and confirm whether the anatomy allows EVAR, plus an echocardiogram, pulmonary function testing, and blood work. Patients are often asked to stop smoking, control blood pressure, and adjust blood thinners under a clinician’s guidance. Statins and, in selected patients, beta-blockers are commonly continued.
On the morning of surgery you generally fast from midnight, arrive a few hours early, and meet the anesthesia team. EVAR patients often walk into the operating room and go home within one to two days. Open repair involves an arterial line, urinary catheter, and a planned ICU stay of one to two nights followed by step-down care. Cardiac risk is the dominant peri-operative concern for both approaches, which is why pre-op cardiology evaluation is common in patients with known coronary disease. Many people pair their workup with a refresher on broader cardiovascular issues from the medical conditions reference library.
Recovery Timeline and Rehabilitation
EVAR recovery is comparatively fast. Most patients go home in 24–48 hours, walk normally within a week, and return to office work in about two to three weeks. Heavy lifting is usually restricted for four to six weeks while the groin access sites heal. Lifelong surveillance imaging (CT or duplex ultrasound) is required to watch for endoleaks, where blood seeps around the graft and can re-pressurize the aneurysm sac.
Open repair takes longer. Hospital stays average about five to eight days, full abdominal healing runs six to twelve weeks, and most people resume normal activity by roughly three months. The trade-off is durability — open grafts rarely require reintervention, whereas EVAR has a meaningful reintervention rate over the following decade (on the order of 15–20 percent) according to long-term randomized trial data. Cardiac rehabilitation, smoking cessation, and a heart-healthy (often Mediterranean-style) diet are commonly advised regardless of approach.
Risks, Complications, and Outcomes
Elective EVAR carries a 30-day mortality of roughly 1–2 percent, while elective open repair runs about 3–5 percent, per Mayo Clinic and vascular-surgery data. Ruptured aneurysm repair, by contrast, carries a far higher operative mortality (commonly cited around 40–50 percent even among those who reach the operating room) — which is exactly why elective repair before rupture, and screening for at-risk patients, matter so much. Common complications include bleeding, stroke, kidney injury from contrast dye, leg ischemia, graft infection, and — for EVAR specifically — endoleaks and graft migration.
When to seek emergency care — rupture is a life-threatening emergency: Call 911 immediately if you experience sudden, severe abdominal, back, or chest pain, a pulsating mass in the abdomen, faintness or fainting, a rapid heartbeat, cold or pale legs, blood in the urine, or new shortness of breath — whether or not you have had aortic repair. These can signal rupture, graft thrombosis, or aortic dissection, all of which are immediately life-threatening. Do not drive yourself to the hospital; call 911 so treatment can begin en route.
Alternatives and When Surgery May Wait (Watchful Waiting)
Small aneurysms (typically below about 5.0–5.5 cm) are usually monitored with ultrasound every 6–12 months rather than repaired — an approach called watchful waiting or surveillance. Blood pressure control, smoking cessation, and statin therapy help slow growth. Aneurysms that remain stable can be watched for years. The UK Small Aneurysm Trial showed that early surgery for sub-5.5 cm aneurysms offered no survival benefit over careful surveillance, which is why most guidelines favor watching small aneurysms and repairing once they cross the threshold or grow rapidly.
Complex aneurysms involving the renal arteries or aortic arch may require fenestrated EVAR (fEVAR), branched grafts, or hybrid procedures available only at specialized centers. Patients who are not surgical candidates because of severe heart or lung disease are sometimes managed medically with strict blood pressure and risk-factor control. If you are also being evaluated for vascular disease elsewhere, the planning often overlaps with a carotid endarterectomy workup or coronary stenting.
Cost Considerations
Costs vary widely by procedure, hospital, region, and insurance, so treat every figure here as an estimate. Without insurance, EVAR typically runs roughly $30,000 to $60,000 in the United States, while open AAA repair often averages $40,000 to $80,000 because of the longer hospital stay. Stent grafts alone can cost $10,000–$20,000. With Medicare or commercial insurance, out-of-pocket costs are usually limited to deductibles, coinsurance, and any out-of-network anesthesia or facility fees. Asking for an itemized estimate before surgery and confirming in-network status for the hospital, surgeon, and anesthesiologist can prevent balance-billing surprises.

Frequently Asked Questions
What are the warning signs of a ruptured aortic aneurysm?
Sudden, severe, and often tearing abdominal, back, or chest pain; faintness or fainting; a rapid heartbeat; a pulsating feeling in the abdomen; and clammy or pale skin. A rupture is a life-threatening emergency — call 911 immediately rather than driving yourself, and do not wait for symptoms to ease.
How long does an EVAR last?
Modern stent grafts are designed to last many years, but lifelong follow-up imaging is required. Roughly 15–20 percent of EVAR patients need a secondary procedure within about 10 years to fix endoleaks or graft migration, compared with under 5 percent for open repair.
Can an aortic aneurysm shrink without surgery?
True shrinkage is uncommon. With aggressive blood pressure control, smoking cessation, and statins, growth often slows. Most aneurysms either stay stable or grow slowly until they reach the surgical threshold, which is why surveillance imaging matters.
What is the recovery like after open AAA repair?
Expect roughly five to eight days in the hospital, four to six weeks of fatigue, and about three months before returning to heavy activity. Walking is encouraged from day one to prevent blood clots and pneumonia. Most patients resume driving at four to six weeks once they no longer need narcotic pain medication.
Will I need lifelong follow-up after aortic aneurysm repair?
Yes, especially after EVAR. Surveillance imaging (often at one month, six months, twelve months, and then annually) is standard. Open-repair patients need imaging less frequently but are still monitored for new aneurysms elsewhere in the aorta.
The Bottom Line
Aortic aneurysm repair has shifted dramatically toward minimally invasive EVAR for eligible patients, but open surgery remains the durable option for complex anatomy and many younger patients. Anatomy, cardiac risk, and lifestyle goals all influence the right choice, and small stable aneurysms are often best watched rather than operated on. Above all, remember that a rupture is a 911 emergency. Ask your vascular surgeon how your specific aneurysm size, location, and CT measurements affect candidacy for EVAR, what their center’s 30-day mortality and reintervention rates are, and what surveillance schedule you should expect. Your vascular surgeon decides whether and when to repair — this page is general information, not medical advice.
