Popliteal artery entrapment syndrome.

Abstract

Popliteal artery entrapment syndrome is an uncommon cause of peripheral vascular disease in young fit individuals, presenting as progressive claudication or sudden limb ischaemia. It can also present later in life with insidious symptoms relating to popliteal thrombosis or aneurysm. As a local cause of atherosclerosis in the popliteal artery it is probably under-diagnosed, as clinical and radiological features are subtle and varied. Early diagnosis and surgical division of aberrant muscular relations result in an excellent clinical result. Late surgical treatment with vein grafting is less durable. The disease incidence, clinical features, pathology, investigations, treatment and prognosis are reviewed.
