BlogWhat is the saphenous vein?
A saphenous vein is a vein in the leg that drains blood out of the leg and back to the heart. Each leg has a great saphenous vein, which travels along the front of the leg, and a small saphenous vein (also called the lesser saphenous vein), which travels along the back of the calf. Saphenous veins are part of the superficial venous system. The legs also have a deep venous system. Most problems related to varicose veins and venous insufficiency are related to leaky valves in the saphenous veins.
