Popliteal artery aneurysm. Prompt intervention prevents tragic consequences

Popliteal artery aneurysm is an important, if uncommon, cause of lower extremity ischemia. About half of cases are asymptomatic. Untreated aneurysms may lead to embolization, rupture, thrombosis, and amputation. Diagnosis involves careful physical examination and use of ultrasound and arteriography. Prompt surgical intervention is essential.
