Supratrochlear vein

Supratrochlear Vein

The veins of the front of the right elbow. (Supratrochlear vein not labeled, but region is visible.)

The Supratrochlear Vein is a superficial vein of the upper limb. It is a part of the venous system of the forearm and hand, and it plays a crucial role in the venous return from these areas.

Anatomy

The Supratrochlear Vein originates from the dorsal venous network of the hand and runs up the anterior aspect of the forearm. It is located medial to the cephalic vein and lateral to the basilic vein. It drains into the median cubital vein at the elbow.

Clinical Significance

The Supratrochlear Vein is often used for venipuncture (the process of obtaining intravenous access for the purpose of intravenous therapy or for blood sampling). Its superficial location makes it an accessible site for venous access, especially in patients with difficult venous access.
