The dorsal metacarpal vein IV (lat. vena metacarpalis dorsalis IV) is a large vein that is located in the area of the fingers on the hand and arm. It is a branch of the palmar arch, and is directed to the fingers through the palmar surface of the limb. In general, the function of the metacarpal dorsal IV vein is to supply the tissues of the hands and fingers with blood and oxygen, as well as remove metabolic waste from this area. Negative effects on this area can lead to impaired blood flow and ischemic diseases.
The vein passes through the skin and fascia, reaching the dorsum of the fingers. It is formed after the confluence of veins coming from the back of the pads of all four fingers and one part
