Open abdominal surgery may be necessary if your aneurysm is very large or has already ruptured. Endovascular surgery is a less invasive form of surgery than open abdominal surgery. It involves using a graft to stabilize the weakened walls of your aorta. If your doctor recommends open abdominal surgery, it may take up to six weeks to recover. Recovery from endovascular surgery only takes two weeks. The success of surgery and recovery greatly depends on whether or not the AAA is found before it ruptures.
Prognosis is usually good if the AAA is found before it ruptures. Focusing on heart health can prevent an AAA. This means watching what you eat, exercising, and avoiding other cardiovascular risk factors such as smoking. Your doctor might also prescribe medicines to treat high blood pressure or cholesterol or to help you control your diabetes. The screening test uses an abdominal ultrasound to scan your aorta for bulges.

An abdominal ultrasound uses sound waves to check a number of conditions. Learn about what ultrasounds are used for and if there are any risks. A dissection of the aorta means that blood has entered the wall of the artery between the inner and middle layers.
These diameters could serve as useful thresholds for decision making in high-operative-risk male patients but may not apply to women 12 or to patients who have low operative risk. The 9. Consistent with this possibility, ineligible patients followed up outside the United Kingdom Small Aneurysm Trial had a higher rupture rate than randomized patients with comparable AAA diameters.
Because most large AAA are surgically repaired, natural history data are difficult to obtain, even in patients at high operative risk, as evidenced by our 47 medical centers requiring 5 years to enroll patients. For this reason, few data exist in the literature, and most predate the introduction of accurate AAA measurement techniques. In , Szilagyi et al 13 reported rupture in 61 of AAA of at least 7 cm among patients who were followed up for a mean of 17 months, a crude rate of Recently, Powell et al 12 observed 0.
Several other studies have also reported rupture rates that are generally consistent with our findings. As expected, AAA diameter was the strongest predictor of rupture in our study. The unexpected protective effects of smoking, myocardial infarction, and coronary artery bypass graft surgery may be artifacts of the high mortality rate. Enlargement rate of AAA was a significant univariate predictor of rupture, but the effect was not significant after adjustment for last measured AAA diameter.
An enlargement rate of at least 1. Our data suggest but do not confirm an independent effect, and further studies are needed to resolve this question. Outcome ascertainment is problematic in studies of AAA rupture because causes of sudden death are difficult to distinguish.
Hospital and nursing home records and eyewitness accounts were therefore important for optimizing outcome assessment in our study. We conclude that the rupture rate is substantial in patients with high operative risk and AAA greater than 5.

Prognosis of patients turned down for conventional abdominal aortic aneurysm repair in the endovascular and sonographic era. J Vasc Surg. Older, long-term smokers are at especially high risk for abdominal aortic aneurysm. Symptoms, when they do occur, include pain in the back or near the naval.
An extremely sharp and severe pain may indicate rupture, requiring emergency medical treatment. Smaller, slow-growing aortic aneurysms may be treated with watchful waiting, lifestyle changes and medication. Large or fast-growing aortic aneurysms may require surgery.
The aorta is the largest blood vessel in the body. It delivers oxygenated blood from the heart to the rest of the body. An aortic aneurysm is a bulging, weakened area in the wall of the aorta. Over time, the blood vessel balloons and is at risk for bursting rupture or separating dissection. This can cause life threatening bleeding and potentially death. Aneurysms occur most often in the portion of the aorta that runs through the abdomen abdominal aortic aneurysm.
An abdominal aortic aneurysm is also called AAA or triple A. A thoracic aortic aneurysm refers to the part of the aorta that runs through the chest. Once formed, an aneurysm will gradually increase in size and get progressively weaker. Treatment for an abdominal aneurysm may include surgical repair or removal of the aneurysm, or inserting a metal mesh coil stent to support the blood vessel and prevent rupture.
The more common shape is fusiform , which balloons out on all sides of the aorta. A saccular shape is a bulge in just one spot on the aorta.
Sometimes this is called a pseudoaneurysm. It usually means the inner layer of the artery wall is torn, which can be caused by an injury or ulcer in the artery. Many things can cause the breakdown of the aortic wall tissues and lead to an abdominal aortic aneurysm. The exact cause isn't fully known. But, atherosclerosis is thought to play an important role.
Atherosclerosis is a buildup of plaque, which is a deposit of fatty substances, cholesterol, cellular waste products, calcium, and fibrin in the inner lining of an artery. Risk factors for atherosclerosis include:. High cholesterol. High blood pressure. In general, the larger the aneurysm and the faster it grows, the greater the risk of rupture.
Aortic aneurysms also increase the risk of developing blood clots in the area. If a blood clot breaks loose from the inside wall of an aneurysm and blocks a blood vessel elsewhere in your body, it can cause pain or block blood flow to the legs, toes, kidneys or abdominal organs.
