The small saphenous vein (SSV), also known as the short saphenous vein, is a superficial vein of the lower limb. It is one of the two major superficial veins of the leg, the other being the great saphenous vein.

Anatomy

The small saphenous vein originates from the dorsal venous arch of the foot and ascends along the posterior aspect of the leg. It typically drains into the popliteal vein at the level of the popliteal fossa. The vein is accompanied by the sural nerve in its course.

Tributaries

The small saphenous vein receives several tributaries along its course, including veins from the lateral and posterior aspects of the leg. It also communicates with the deep venous system through perforating veins.

Variations

There are several anatomical variations in the course and drainage of the small saphenous vein. In some individuals, it may drain into the great saphenous vein or directly into the femoral vein.

Clinical significance

The small saphenous vein is often involved in varicose veins, which are dilated and tortuous veins that can cause discomfort and cosmetic concerns. Treatment options for varicose veins include sclerotherapy, endovenous laser treatment, and surgical ligation.
