Overview

A popliteal aneurysm is a bulge in a blood vessel (artery) behind your knee. The bulge occurs in a weak spot in the artery. It may occur in one or both legs.

Blood clots can form in this type of aneurysm and block blood flow in your leg. A small aneurysm may not need surgery, although your doctor will watch it closely.

Having a popliteal aneurysm means you may also have a higher risk of heart disease. There are many things you can do to improve your heart health. Doing these things may also prevent more damage to your blood vessels.
