Popliteal Aneurysm

Popliteal aneurysm is the most common peripheral arterial aneurysm, often bilateral and associated with abdominal aortic aneurysm. It may be asymptomatic or cause distal embolism/thrombosis leading to limb ischemia. Treatment: elective repair (open bypass/endovascular) for aneurysms >2 cm, symptomatic, thrombosed, or embolic; acute limb ischemia - urgent thrombectomy/revascularization; screen for contralateral popliteal and abdominal aortic aneurysm; control atherosclerosis risk factors.

Common Symptoms

Pulsatile popliteal mass; distal embolism/thrombosis; limb ischemia; often bilateral/associated AAA

Causes and Pathogenesis

Atherosclerotic degenerative dilatation of the popliteal artery with mural thrombus and distal embolism risk.

Treatment

Elective repair for >2 cm/symptomatic; urgent revascularization for acute ischemia; screen associated aneurysms

Preventive Measures

Screen associated aneurysms; control atherosclerosis; repair before thrombosis.

Department to Visit

It is recommended to visit the Vascular-surgery department; an appointment can be booked on this platform before the visit.
