Abdominal aortic aneurysm (dilation)

About Abdominal aortic aneurysm (dilation)

A weakened portion of the abdominal aorta that expands. The abdominal aorta is the large artery in the abdomen that carries blood to the abdomen and legs. This weakened section can continue to expand, dissect, or rupture. A rupture of the aneurysm is a life threatening condition, leading to rapid blood loss and if left untreated death. A dissection of the aorta is a separation of the layers of the aorta and can occlude blood vessels to the abdominal organs (intestines, kidneys, etc.) and legs.

Symptoms

An abdominal aortic aneurysm can cause abdominal pain, back pain, vomiting, weakness, fainting or death. Some patients may not have symptoms especially if the aneurysm is small.

Tests & Diagnostics

A history and physical exam will be performed. An abdominal aortic aneurysm can be diagnosed by ultrasound or CT scan. A CT scan is the only way the doctor can determine if the aneurysm is bleeding.

Common tests: Complete blood count (CBC), Comprehensive metabolic panel (CMP), CT Scan, EKG, Troponin, Ultrasound.

Conventional treatment summary

An abdominal aortic aneurysm can be repaired surgically, or with a special catheter and an intra-abdominal sheath. Some aneurysms, usually less than 5 centimeters, can be treated with watchful waiting.
