Abstract

Knowledge of anatomical variations is important so as to avoid potential iatrogenic injury or misdiagnosis on imaging. Here we report an unusual finding and relationship between the tibial nerve and popliteal vein. During the routine dissection of an adult cadaver, it was noted that a branch of the tibial nerve in the popliteal fossa pierced the most distal part of the popliteal vein. This unusual finding is described and relevant reports in the literature discussed. Our hopes are that such a report might help surgeons avoid injury to such a fenestrated popliteal vein and the tibial nerve branch traveling through it therefore decreasing patient morbidity.
