Great
Saphenous Vein.
Great Saphenous Vein (pronunciation: /ˈsæfɪnəs/ veɪn) is the largest vein in the human body, extending from the foot to the groin. It is often used in coronary artery bypass surgery.
Etymology
The term "saphenous" is derived from the Greek word "saphēnós," meaning "clearly visible." The "great" in Great Saphenous Vein refers to the vein's size and length, distinguishing it from the Lesser Saphenous Vein, which is smaller and shorter.
Anatomy
The Great Saphenous Vein originates from the dorsal venous arch in the foot, travels up the medial side of the leg, and empties into the Femoral Vein in the groin. It has numerous tributaries, including the Anterior Accessory Saphenous Vein and the Posterior Accessory Saphenous Vein.
Clinical Significance
The Great Saphenous Vein is often used in Coronary Artery Bypass Grafting (CABG) because of its size and accessibility. It can also be affected by Varicose Veins, a condition where the vein becomes enlarged and twisted due to weak or damaged valves.
