In human anatomy, the cephalic vein (also known as the antecubital vein)is a superficial vein of the upper limb. It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle.ermanent pacemaker leads are often placed in the cephalic vein in the deltopectoral groove. The vein may be used for intravenous access, and is sometimes referred to as the 'House-man's Friend' because a large bore cannula may be easily placed.
Where it ends, near the neck of the pancreas, it forms the hepatic portal vein by coming together with the splenic vein. Other tributaries of SMV drain other organs such as the stomach, large intestine, and appendix. Some of these include the middle colic vein, right colic vein, veins from the ileum, and veins from the jejunum. Thrombosis is the only pathologic disorder associated with this vein and it is uncommon. Thrombosis is a blood clot in a blood vessel, which leads to restricted blood flow and circulation throughout the body.
