Abstract

Popliteal artery aneurysms (PAAs) account for approximately 70% of all peripheral artery aneurysms. Despite the exact prevalence of PAAs being unknown, it is thought to be present in about 1% of the elderly male population. Acute thrombus in a PAA can increase the risk of lower limb ischemia and amputation. We present a case documenting an incidental finding of an asymptomatic "floating" or pedunculated thrombus within a left PAA on duplex ultrasound. This thrombus resolved following a period of anticoagulation with intravenous Heparin followed by oral administration of apixaban.
