Vienna Unnamed Right

The right innominate vein (lat. v. anonyma dextra) is one of the veins of the human forearm.

The right innominate vein belongs to the superficial veins of the upper limb. It is located on the palmar surface of the right forearm.

The right innominate vein begins from the palmar venous plexus. Then it runs up the forearm lateral to the artery of the same name. In the upper third of the forearm, the innominate vein flows into the ulnar vein, being one of its tributaries.

The diameter of the right innominate vein is about 2-3 mm. Like other superficial veins, it contains valves that prevent blood from flowing back.

The right innominate vein plays an important role in the outflow of venous blood from the hand to the deep veins of the forearm. Damage to this vessel can disrupt venous blood flow and lead to the development of edema.
