Popliteal artery entrapment syndrome

The popliteal artery entrapment syndrome is a rather uncommon pathology, which results in claudication and chronic leg ischemia. The popliteal artery may be compressed behind the knee, due to congenital deformity of the muscles or tendon insertions of the popliteal fossa. This repetitive trauma may result in stenotic artery degeneration, complete artery occlusion or even formation of an aneurysm.
