A peripheral aneurysm is an enlargement or weakened area in an artery other than your aorta. It mostly affects the arteries in your legs or neck.
Surgeons at the UPMC Division of Vascular Surgery are experts in treating peripheral aneurysms. We use minimally invasive techniques and open surgical repair, depending on the extent of your condition.
And, our team approach to care means a quick and accurate diagnosis and a peripheral aneurysm treatment plan that’s right for you.

An aneurysm is an enlargement or weakened area of an artery. Aneurysms are more common in the aorta — your body’s largest blood vessel — but can occur in any artery.
A peripheral aneurysm is an enlargement or weakened area in an artery other than your aorta, often in your legs or neck.
A mesenteric (splenic, hepatic, or celiac) aneurysm occurs in an artery located in the abdomen, but not in your aorta.
Other types of peripheral aneurysms can affect the:
Peripheral aneurysms affect men and women.
They are most common in people who have:
Women may get splenic aneurysms during pregnancy, and they are more common among women who have had many children.
While the risk of a rupture (when the aneurysm bursts) is low with peripheral aneurysms, they can lead to blood clots. Blood clots block blood flow or shower downstream.
If a clot blocks blood flow for an extended time, this can lead to tissue or organ loss.
Peripheral aneurysms may also put pressure on surrounding nerves or veins. This can cause pain, numbness, or swelling.
Peripheral aneurysms don't always cause symptoms. Your doctor may diagnose a peripheral aneurysm by chance during an exam or while testing for other health problems.
