The Right Innominate Vein (also known as the Right Brachiocephalic Vein) is a large vein in the upper chest and neck region of the human body. It is formed by the union of the Internal Jugular Vein and the Subclavian Vein on the right side of the body.

Structure

The Right Innominate Vein is typically around 2.5 cm in length and is located anterior to the Right Innominate Artery. It runs obliquely downward and medially, passing in front of the Trachea to join the Left Innominate Vein and form the Superior Vena Cava.

Function

The primary function of the Right Innominate Vein is to return deoxygenated blood from the head, neck, and upper limb on the right side of the body to the heart.

Clinical Significance

Due to its location and size, the Right Innominate Vein can be involved in various medical conditions, such as Deep Vein Thrombosis and Superior Vena Cava Syndrome. It is also a common site for the placement of Central Venous Catheters and Pacemakers.
