However, its anatomic features, accepted treatment approaches, and clinical outcomes after treatment supported its role as a truncal vein, similar to the great saphenous vein (gsv) and small saphenous vein (ssv). Discover the accessory saphenous vein's origin, course, and drainage in the human body. Incompetence of the aasv, often without gsv incompetence, is found in about 10% of limbs with varicose veins As to the clinical appearance of isolated aasv incompetence, this typically presents as varicose veins, coursing from the anterior thigh to the lateral knee and calf. Understanding the anatomy, tributaries, and clinical significance of the accessory saphenous vein is crucial for accurate diagnosis and effective treatment of venous disorders. Finally, the last revision of the ceap classification introduced the anterior (accessory) saphenous vein and clearly discriminated it from other superficial veins.
It runs upward behind the medial condyles of the tibia and femur and along the medial side of the thigh and, passing through the fossa ovalis, ends in the femoral vein. The accessory saphenous vein refers to either the posterior or anterior tributary that joins the great saphenous vein in the lower portion of the leg The anterior accessory saphenous vein is a common vein that drains the skin and superficial fascia of the medial side of the thigh. By definition, the accessory saphenous veins, their collateral tributaries, and communicating veins the saphenous compartment However, the anterior “accessory” saphenous vein is not superficial but has been found to lie in a defined interfascial compa subcutaneous layer, and parallel to the gsv
