What is Popliteal artery aneurysm?

It is a vascular anomaly in the popliteal artery located in the back of the knee, producing a bulge in the weakened arterial wall.

Various causes give rise to a popliteal artery aneurysm, including:

Atherosclerosis.
High blood pressure.
Weakening due to natural wear of the popliteal artery.
