Lesser saphenous vein

The small saphenous vein (also short saphenous vein or lesser saphenous vein), is a relatively large superficial vein of the posterior leg.Cross-section through middle of leg.Nerves of the dorsum of the foot. The small saphenous vein (also short saphenous vein or lesser saphenous vein), is a relatively large superficial vein of the posterior leg. The origin of the small saphenous vein, (SSV) is where the dorsal vein from the fifth digit (smallest toe) merges with the dorsal venous arch of the foot, which attaches to the great saphenous vein (GSV). It is a superficial vein being subcutaneous, (just under the skin). From its origin, it courses around the lateral aspect of the foot (inferior and posterior to the lateral malleolus) and runs along the posterior aspect of the leg (with the sural nerve), where it passes between the heads of the gastrocnemius muscle. This vein presents a number of different draining points: Usually it drains into the popliteal vein, at or above the level of the knee joint. Sometimes the SSV joins the common gastrocnemius vein before draining in the popliteal vein.
