Subclavian

Subclavian refers to structures in the human body that are located beneath the clavicle (collarbone). The term is most commonly used in relation to the Subclavian artery and the Subclavian vein, which supply blood to and from the upper limb, respectively.

Subclavian Artery

The Subclavian artery is a major artery of the upper body, supplying blood to the head, neck, and arms. It originates from the aortic arch on the left side of the body and from the brachiocephalic trunk on the right side. The subclavian artery is divided into three parts, with different branches arising from each part.

Subclavian Vein

The Subclavian vein is a large vein that drains blood from the upper limb, chest wall, and neck. It is formed by the union of the axillary vein and the cephalic vein, and it empties into the superior vena cava.

Clinical Significance

The subclavian structures are important in a number of clinical procedures, including central venous catheterization and subclavian steal syndrome. Damage to the subclavian artery or vein can result in significant blood loss and potentially life-threatening complications.
