Deep Brachial Vein

vena brachialis profunda

The deep brachial vein accompanies the profunda brachii artery in the spiral groove of the humerus and drains the deep structures of the posterior upper arm including the triceps. It joins the brachial venous system or the radial collateral vein at the lateral intermuscular septum.

Region: Upper Arm

Clinical Relevance

Clinical Notes

The deep brachial vein is not routinely imaged but is an important consideration during posterior humeral approaches, where injury to the profunda brachii vessels in the spiral groove produces significant haemorrhage. Upper extremity deep vein thrombosis occasionally involves the deep brachial vein, producing arm swelling and pain requiring anticoagulation. It is included in comprehensive upper limb venous duplex studies.

Common Injuries & Conditions

Posterior Humeral Approach Haemorrhage

Profunda brachii vessel injury in the spiral groove during posterior humeral plating, producing significant haematoma formation in the posterior arm compartment.
