Popliteal artery entrapment syndrome (PAES) is a rare progressive vascular disease. The clinical presentation ranges from asymptomatic to intermittent claudication, cramping, swelling, and paresthesias due to compression of popliteal artery at the proximal posterior calf (1). Physical examination findings may be nonspecific, including muscular tenderness to palpation, leg swelling, decreased distal sensation, coolness to touch, and diminished dorsal pedis and posterior tibial artery pulses (1,2). Early diagnosis and treatment are important as PAES can be progressive and lead to distal ischemia. However, PAES is a diagnostic challenge andmay require one ormore imaging studies such as ultrasound, Duplex ultrasound (DUS), arterial-brachial indices (ABIs), angiography, magnetic resonance angiography (MRA), or computed tomography angiography (CTA) (1–3). Mild cases are monitored and conservatively managed with activity modifications. Popliteal artery release surgery, vascular bypass surgery, and endarterectomy are definitive surgical options (2).
