Great Saphenous Vein
The Great Saphenous Vein (GSV) is the largest vein in the human body, and is also known as the long saphenous vein. It is a superficial vein, meaning it is close to the surface of the body, and it runs along the length of the lower limb, returning blood from the foot, leg and thigh to the deep femoral vein at the femoral triangle.
Anatomy[edit | edit source]
The GSV originates from where the dorsal vein of the first digit (big toe) merges with the dorsal venous arch of the foot. After this junction, it runs up in front of the medial malleolus (part of the tibia bone) and along the medial side of the leg. At the knee, it runs over the posterior border of the medial epicondyle of the femur bone. The vein then courses up the medial side of the thigh to ultimately join with the femoral vein.
Clinical Significance[edit | edit source]
The Great Saphenous Vein is often used in coronary artery bypass surgery. The vein is harvested from the leg and used to bypass blocked coronary arteries. This is possible because veins can handle the lower pressure environment found in veins as compared to arteries.
In addition, the GSV can become varicose, a condition known as varicose veins. This is when the vein becomes enlarged and overfilled with blood, causing it to appear raised and swollen. Varicose veins can cause aching pain and discomfort, and in some cases, can lead to more serious problems.
