|Source||dorsal venous arch of the foot|
|Drains to||popliteal vein|
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:
Sometimes the SSV joins the common gastrocnemius vein before draining in the popliteal vein.
Sometimes it doesn't make contact with the popliteal vein but goes up to drain in the GSV at a variable level.
