Median antebrachial vein

The median antebrachial vein is a superficial vein of the upper limb. It is located in the forearm and is responsible for draining blood from the hand and forearm. This vein is often used for venipuncture and intravenous access due to its accessibility.

Anatomy

The median antebrachial vein originates from the venous plexus on the palmar surface of the hand. It ascends on the anterior aspect of the forearm, typically running alongside the median nerve. The vein may vary in its course and can sometimes be absent or replaced by other superficial veins.

Tributaries and Connections

The median antebrachial vein receives blood from the superficial veins of the hand and forearm. It often communicates with the cephalic vein and the basilic vein through the median cubital vein at the level of the elbow. These connections are important for the venous return from the upper limb.

Clinical Significance

The median antebrachial vein is frequently used for medical procedures such as venipuncture, where blood samples are drawn, and for the insertion of intravenous catheters. Its superficial location makes it an accessible site for these procedures. However, variations in its anatomy can sometimes pose challenges.
