can a abdominal aortic aneurysm shrink?

The stent graft reinforces the weakened aorta and eventually the aneurysm will shrink around the graft. Under experienced care, this procedure is often possible with essentially no incisions—only punctures.

The bulging occurs when the wall of the aorta weakens. Although what causes this weakness is unclear, smoking and high blood pressure are thought to increase the risk of an aneurysm. AAAs are most common in men aged over 65. A rupture accounts for more than 1 in 50 of all deaths in this group.

Emerging evidence suggests high prevalence of abdominal aortic aneurysm (AAA) among patients with coronary disease.

Abdominal aortic aneurysms do not go away, so if you have a large one, you may need surgery. Surgery involves replacing the aneurysm with a man-made graft. Elective surgery, which is done before an aneurysm ruptures, has a success rate of more than 90 percent.

Heart Disease - Aortic Aneurysm. An aortic aneurysm is the bulging of a portion of the aortic wall. Aortic aneurysms are believed to be caused by the gradual weakening of the artery due to atherosclerosis, arterial narrowing and hardening from cholesterol plaque build-up.

['Pain in the chest, belly (abdomen), lower back, or flank (over the kidneys). ... ', 'A pulsating feeling in the belly.', 'A "cold foot" or a black or blue painful toe. ... ', 'Fever or weight loss, if the aneurysm was caused by infection or inflammation (inflammatory aortic aneurysm).']

Smoking is the strongest risk factor. It can weaken the aortic walls, increasing the risk not only of developing an aortic aneurysm, but of rupture. The longer and more you smoke or chew tobacco, the greater the chances of developing an aortic aneurysm.

This could cause a leak that spills blood into your body. Some aortic aneurysms burst, some don't. Others force blood flow away from your organs and tissues, causing problems, such as heart attacks, kidney damage, stroke, and even death.

Treating an abdominal aortic aneurysm Depending on the size and exact location of the aneurysm, your doctor may perform surgery to repair or remove the damaged tissue. This may be done either with open abdominal surgery or endovascular surgery.

Open-chest surgery. Open-chest surgery to repair a thoracic aortic aneurysm generally involves removing the damaged section of the aorta and replacing it with a synthetic tube (graft), which is sewn into place. It generally takes a month or more to fully recover from this procedure.

An 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 your heart through the center of your chest and abdomen.

In general, the larger the aneurysm and the faster it grows, the greater the risk of rupture. Signs and symptoms that your aortic aneurysm has ruptured can include: Sudden, intense and persistent abdominal or back pain, which can be described as a tearing sensation. Low blood pressure.

Abdominal aortic aneurysm (also known as AAA, pronounced "triple-a") is a localized dilatation (ballooning) of the abdominal aorta exceeding the normal diameter by more than 50 percent.

The normal diameter of the ascending aorta has been defined as <2.1 cm/m2 and of the descending aorta as <1.6 cm/m2. The normal diameter of the abdominal aorta is regarded to be less than 3.0 cm.

In most cases, doctors will run a catheter through the patient's femoral artery in the groin to the site of the aneurysm in the aorta, then implant a stent graft. The stent graft reinforces the weakened aorta and eventually the aneurysm will shrink around the graft.

The doctor makes a large cut (incision) in the belly or the side of the abdomen. The doctor puts clamps on the aorta above and below the aneurysm. This stops blood flow through the area that the doctor is working on. The doctor removes the aneurysm and attaches the graft to the aorta.

Most people with aortic aneurysms don't have symptoms unless a tear or rupture occurs. A dissection or rupture is a medical emergency. Call 911 or your local emergency number for immediate assistance.
