Small Saphenous Vein

The Small Saphenous Vein (Latin: vena saphena parva) is a significant vein in the human body that carries deoxygenated blood from the lower leg back to the heart. It is one of the two main superficial veins of the lower limb, the other being the Great Saphenous Vein.

Anatomy[edit | edit source]

The Small Saphenous Vein originates from the lateral end of the dorsal venous arch, which is located on the top of the foot. It ascends behind the lateral malleolus, a bony prominence on the outer aspect of the ankle, and then runs up the back of the leg.

In the lower third of the leg, it pierces the deep fascia, a layer of fibrous connective tissue, and continues its ascent in the company of the sural nerve, a sensory nerve in the calf. It drains into the Popliteal Vein at or above the level of the knee joint.

Clinical Significance[edit | edit source]

The Small Saphenous Vein is often affected by varicose veins, a common condition characterized by dilated and tortuous veins. This can lead to symptoms such as pain, swelling, and skin changes in the affected leg.

In addition, the vein can be used for venous access in medical procedures, such as the insertion of a peripheral venous catheter for the administration of fluids and medications.
