Popliteal vein entrapment syndrome associated with an accessory slip of the lateral head of the gastrocnemius muscle

Popliteal vein entrapment syndrome (PVES) is a rare subtype of popliteal entrapment syndrome that leads to symptoms of chronic venous stasis. Herein, we report a case of isolated PVES in a young patient associated with an accessory slip of the lateral head of the gastrocnemius muscle. The patient underwent resection of the anomalous muscle, and the symptoms relieved postoperatively. PVES should be considered in young patients with unexplained symptoms or signs of venous stasis. Surgical resection of the causative lesion compressing the popliteal vein is indicated for selected patients.
