Quick Facts
Origin: Radial recurrent vein.
Course: Superiorly in the arm.
Tributaries: Medial collateral and radial recurrent veins.
Drainage: Posterior aspect of the arm.
Origin
The deep brachial vein is a continuation of the radial recurrent vein.
Course
The deep brachial vein courses superiorly along the arm.
Tributaries
In the distal arm, the middle collateral and radial recurrent veins join the deep brachial vein. In the proximal arm, it unites with the deltoid branch of the deep brachial vein, the brachial vein, and with the superficial venous drainage via the basilic vein.
Structures Drained
The deep brachial vein contributes to the drainage of the posterior aspect of the arm.
