Entrapment of the popliteal artery

Popliteal artery entrapment is a rare but recognized cause of vascular insufficiency of the lower extremity. The authors describe the condition in a 26-year-old man. Diagnosis depends on arteriographic demonstration of the lesion. Treatment is surgical and should consist of either a bypass procedure or excision with graft interposition. Acute onset of peripheral vascular symptoms in a young person should arouse suspicion of such a lesion.
