Peripheral Aneurysms

A peripheral aneurysm is an aneurysm that occurs in arteries other than the aorta. These most commonly occur in the popliteal artery, which runs down the back of your lower thigh and knee, but can also occur in the femoral artery (groin), the carotid artery (neck) or sometimes the arteries in the arms.

A special type of peripheral aneurysm that forms in the arteries feeding the kidneys or the bowel is called a visceral aneurysm.

While peripheral aneurysms do not rupture as often as aortic aneurysms, they are more likely to create blood clots that can block the flow of blood to limbs or the brain.
