Saphenous vein

The Saphenous vein is the largest vein in the human body, extending from the foot to the upper thigh and groin. It is a superficial vein, meaning it is close to the surface of the body. The saphenous vein is often used in coronary artery bypass surgery and is the most commonly used vein for this procedure.

Anatomy

The saphenous vein is divided into two main branches: the Great saphenous vein (GSV) and the Small saphenous vein (SSV). The GSV begins at the foot and extends up the inner side of the leg, thigh, and groin. The SSV starts at the foot and runs up the back of the calf and thigh.

Function

The primary function of the saphenous vein is to transport deoxygenated blood from the foot back to the heart. It also plays a crucial role in thermoregulation, helping to cool the body down when it is overheated and warm it up when it is cold.

Clinical significance

The saphenous vein is often used in Coronary artery bypass surgery to bypass blocked coronary arteries and improve blood flow to the heart. It is also used in Varicose veins treatment, where it is often removed in a procedure called Saphenous vein stripping.
