Vena saphena

Vena Saphena is a term used in anatomy to refer to two large superficial veins of the leg, the Vena Saphena Magna and the Vena Saphena Parva. These veins are significant in the circulatory system and are often used in medical procedures such as coronary artery bypass surgery.

Vena Saphena Magna

The Vena Saphena Magna, also known as the great saphenous vein, is the longest vein in the body. It originates from the dorsal vein of the big toe and runs up the medial side of the leg, the thigh, and the groin. It drains into the femoral vein, which carries blood back to the heart.

Vena Saphena Parva

The Vena Saphena Parva, or small saphenous vein, originates from the lateral side of the foot and runs up the back of the leg. It drains into the popliteal vein behind the knee.

Clinical Significance

The vena saphena veins are often used in medical procedures due to their size and accessibility. In coronary artery bypass surgery, a segment of the vena saphena magna is often harvested and used to bypass a blocked coronary artery. The vena saphena veins can also be affected by varicose veins, a condition where the veins become enlarged and twisted.
