BACKGROUND Venous anomalies of the lower extremity are a challenge when found as rare variations. Physicians should be aware of morphological variations in this region for correct diagnosis and management of diseases such as deep vein thrombosis. MATERIALS AND METHODS During the routine dissection of the lower extremities of a Caucasian male cadaver, a case of persistent sciatic vein was found. RESULTS A persistent sciatic vein originating from the saphenopopliteal junction coursed proximally and laterally to enter into the adductor magnus muscle, at the right side. Running through the fibers of the adductor magnus anteriorly, the variant vein drained into the deep femoral vein just medial to the vastus medialis muscle. CONCLUSIONS As being a rare congenital vascular anomaly, the persistent sciatic vein should be correctly diagnosed and defined during the radiologic assessments, surgical interventions and blockades for better outcomes and lesser complications.
