The great saphenous vein (GSV) or long saphenous vein (/ s ə ˈ f iː n ə s /) is a large, subcutaneous, superficial vein of the leg.It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot, leg and thigh to the deep femoral vein at the femoral triangle.
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible. The great saphenous vein is most

The femoral vein continues into the thigh as the continuation from the popliteal vein at the back of the knee. It drains blood from the deep thigh muscles and thigh bone. [2] Proximal to the confluence with the deep femoral vein, and the joining of the great saphenous vein, the femoral vein is widely known as the common femoral vein. [3]
The GSV, a superficial vein, is the longest vein in the body. It has its origin in the dorsal venous arch of the foot, a superficial vein which connects the small saphenous vein with the GSV. It travels up the leg and medial side of the thigh to reach the groin, where it drains into the common femoral vein. [32]
The anterior accessory saphenous vein is a special anterior tributary of the great saphenous vein (GSV), draining the antero-lateral face of the thigh. It becomes very often insufficient, causing important varicose veins with an autonomous course and often is the only insufficient vein present on a patient.
Procedures such as saphenous vein cutdown or orthopedic surgery that includes incisions or dissection over the distal tibia or medial malleolus can result in damage to the saphenous nerve, resulting in loss of cutaneous sensation in the medial leg. This is due to the intimate path that the saphenous nerve and the great saphenous vein travel.
Venous cutdown procedures most commonly target the great saphenous vein in the leg because it is superficial, easily accessible, and consistently in the same anatomical location. This procedure is used in certain populations such as critically ill patients or patients in hypovolemic shock or when less invasive methods such as peripheral ...
