The anterior accessory saphenous vein is a small vein that runs along the lateral side of the lower leg. It arises from the dorsal venous arch and descends superficially to join the great saphenous vein just below the knee. It is used in surgical procedures as a bypass graft for coronary artery disease and as a conduit for dialysis access. Variations exist in its course and connections with other veins, and it receives tributaries from the anterolateral leg. It plays a role in venous insufficiency, a condition characterized by impaired blood flow in the veins, leading to leg swelling and pain. Treatment options for venous insufficiency include non-surgical measures like compression therapy and sclerotherapy, as well as surgical interventions such as vein stripping and ligation.
