ABSTRACT
The great and small saphenous veins are bounded by muscular fascia below and saphenous fascia above. The small saphenous vein drains the subcutaneous tissues from the medial malleolus and then stays posteriorly as it rises to the saphenopopliteal junction, although this connection is variable (1). The great saphenous vein lies medially as it drains the medial calf and then ascends the thigh to join the common femoral vein. The superficial veins can be easily visualized sonographically in most patients. Perforating veins connect the deep and superficial veins at multiple levels in the calf. There are fewer perforators in the thigh. These veins drain blood from the skin to the deep veins.
