The Marginal Vein is a superficial vein that is not always present in the human body. It is also known as the Vein of Servelle. This vein is typically found in the upper limb and runs along the radial margin of the forearm when the palm is facing forward.

Structure

The Marginal Vein, when present, originates from the dorsal venous network of the hand. It then ascends along the radial side of the forearm and drains into the Cephalic Vein near the elbow. It is a superficial vein, meaning it is close to the surface of the body.

Clinical Significance

The Marginal Vein can be used for venipuncture, the process of obtaining intravenous access for the purpose of intravenous therapy or for blood sampling. However, due to its variable presence, it is not always a reliable site for venipuncture.
