Ulnar vein

The Ulnar vein is a vein that carries deoxygenated blood from the lower lateral (ulnar) part of the forearm to the heart. It runs parallel to the ulnar artery and is often visible through the skin in individuals with low body fat.

Anatomy[edit | edit source]

The ulnar vein begins at the hand, where it is formed by the confluence of the superficial and deep venous palmar arches. It then ascends along the ulnar side of the forearm, deep to the flexor carpi ulnaris muscle. At the elbow, it joins the radial vein to form the brachial vein.

Clinical significance[edit | edit source]

The ulnar vein is often used for venipuncture (the process of obtaining intravenous access for the purpose of intravenous therapy or for blood sampling). However, due to its location, it can be more difficult to access than other veins in the arm.
