Venous drainage of the distally based lesser saphenous-sural veno-neuroadipofascial pedicled fasciocutaneous flap: a radiographic perfusion study.

Abstract

The drainage pathway of the distally based lesser saphenous-sural veno-neuroadipofascial pedicled fasciocutaneous flap using accompanying arteries of the lesser saphenous vein and sural nerve as nutrient vessels of the flap was radiographically investigated using five fresh cadavers. Small long veins existed along the lesser saphenous vein, and they were considered to be concomitant veins of the accompanying arteries of the lesser saphenous veins. They anastomosed with the lesser saphenous vein in some places and played a role in bypassing valves in the lesser saphenous vein.
