OverviewAn abdominal aortic aneurysm is an enlarged area in the lower part of the major vessel that supplies blood to the body (aorta). The aorta runs from the heart through the center of the chest and abdomen. Show
The aorta is the largest blood vessel in the body, so a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Depending on the size of the aneurysm and how fast it's growing, treatment varies from watchful waiting to emergency surgery. SymptomsAbdominal aortic aneurysms often grow slowly without noticeable symptoms, making them difficult to detect. Some aneurysms never rupture. Many start small and stay small. Others grow larger over time, sometimes quickly. If you have an enlarging abdominal aortic aneurysm, you might notice:

CausesAneurysms can develop anywhere along the aorta, but most aortic aneurysms occur in the part of the aorta that's in the belly area (abdomen). Several things can play a role in the development of an abdominal aortic aneurysm, including:
Risk factorsAbdominal aortic aneurysm risk factors include:
If you're at risk of an aortic aneurysm, your doctor might recommend other measures, such as medications to lower your blood pressure and relieve stress on weakened arteries. ComplicationsTears in one or more of the layers of the wall of the aorta (aortic dissection) or a ruptured aneurysm are the main complications. A rupture can cause life-threatening internal bleeding. In general, the larger the aneurysm and the faster it grows, the greater the risk of rupture. Signs and symptoms that an aortic aneurysm has ruptured can include:
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. PreventionTo prevent an aortic aneurysm or keep an aortic aneurysm from worsening, do the following:
Aug. 27, 2021 Which of the following areas is an abdominal aortic aneurysm most commonly located?Aneurysms can develop anywhere along the aorta, but most aortic aneurysms occur in the part of the aorta that's in the belly area (abdomen). Several things can play a role in the development of an abdominal aortic aneurysm, including: Hardening of the arteries (atherosclerosis).
Where are abdominal aortic aneurysm located?An aneurysm is a weak section of an artery wall. Pressure from inside the artery causes the weakened area to bulge out beyond the normal width of the blood vessel. An abdominal aortic aneurysm is an aneurysm in the lower part of the aorta, the large artery that runs through the torso.
Where do the majority of abdominal aortic aneurysms begin?AAAs typically begin below the renal arteries (infrarenal) but may include renal arterial ostia; about 50% involve the iliac arteries. Generally, aortic diameter ≥ 3 cm constitutes an AAA. Most AAAs are fusiform (circumferential widening of the artery).
Where are aneurysms most commonly found?The most common location of an aneurysm is the aorta, which carries oxygenated blood from the heart to the body. The thoracic aorta is the short segment of the aorta in the chest cavity. The abdominal aorta is the section of the aorta that runs through the abdomen.
