The median antebrachial vein arises from the superficial veins of the palmar aspect of the hand.


The median antebrachial vein courses superiorly and drains into the median cubital vein or directly into the basilic vein. However, in up to a quarter of individuals, it may divide distal to the elbow where one branch joins the cephalic vein and the other joins the basilic vein (Tubbs et al., 2016, Standring, 2016).


There are no named tributaries.

Structures Drained

The median antebrachial vein contributes to the venous drainage of the palmar aspect of the hand and anterior forearm.
