Giacomini’s vein – a report on the invaluable importance of an anomalous short saphenous vein

Abstract

Abstract Variations in the drainage (termination) and course of the lower limb veins are not uncommon. When dissecting the left lower limb of the adult male cadaver in the vascular case described herein, a unique kind of unilateral short saphenous vein (SSV) termination was observed. It was found that the SSV had normal origin and course in the dorsum of the foot and the back of the leg, respectively. Most often the SSV terminates in the popliteal vein at the popliteal fossa. In this case, it extended upward into the back of the thigh, passing behind the sciatic nerve and then deep to it and the biceps femoris, and finally ended in the veins of the thigh. The SSV did not penetrate any structures along its course to the end, so this unusual vein appears unlikely to be associated with SSV varicose veins. For general, plastic, cardiothoracic, and vascular surgeons, our case would be of significant value.
