Arterial Aneurysms

An aneurysm is a ballooning or swelling of an artery. Aneurysms most commonly occur in the abdominal aorta, which is the major artery in the lower half of the body that carries oxygenated blood from the heart to the rest of the body. Aneurysms of the aorta raise concern because they can rupture, causing potentially fatal bleeding.

Vascular surgeons at UCSF Medical Center have been pioneers in advancing both conventional and endovascular treatment of aortic aneurysms. UCSF has the most extensive experience in the nation with conventional surgery for complex aortic aneurysms — those that involve the arteries to the kidneys or intestines — and is recognized as having one of the lowest mortality rates reported to date.

Similarly, our surgeons pioneered endovascular repair of aneurysms, particularly those involving the aorta in the upper abdomen where branches arise and in the chest. We also are involved in clinical trials of new endovascular devices to treat aneurysms and have one of the largest endovascular aneurysm treatment programs in the world.
