What's it mean to have femoral artery aneurysm?

Risk of rupture: Aneurysm is an abnormal dilatation of a blood vessel and may result in rupture of blood vessel, in this case femoral artery, with bleeding into surrounding tissues or externally and can be fatal.

Abnormal swelling: There are 2 basic types of femoral aneurysms- pseudoaneurysms- frequently caused by angiograms, and true aneurysms. Pseudoaneurysm treatment depends on the size, but should be assessed by a vascular surgeon. True aneurysms are treated depending on size, and have the risk of clotting off or tossing debris down the leg. They are also associated with a higher risk of aneurysms of the aorta.
