The subclavian vein is the major vein of the arm, shoulder and neck. Its name means ‘under the clavicle’, due to the course it takes when entering the thorax. We will discuss the detailed anatomy of this vein in order to give a three dimensional understanding.
The subclavian veins are the major veins that drain the upper limbs. Gross anatomy Origin and course. The subclavian vein is the continuation of the axillary vein as it crosses the lateral border of the 1 st rib.
The subclavian vein is a paired large vein, one on either side of the body, that is responsible for draining blood from the upper extremities, allowing this blood to return to the heart.
The subclavian vein (SVC) is classified as a deep vein and is the major venous channel that drains the upper extremities. Other deep veins of the upper extremity that accompany the major arteries include the radial, ulnar, brachial, axillary veins.
The subclavian vein is a large, deep, paired vein that drains blood from the arms and shoulders, transporting blood back to the heart.
The subclavian veins will merge with the internal jugular veins from the head to form the brachiocephalic veins. The brachiocephalic vein from each upper extremity will merge to form the superior vena cava.
Quick Facts. Origin: Axillary vein. Course: Superomedially, to the internal jugular vein where it forms the brachiocephalic vein. Tributaries: External jugular vein and thoracic duct (left) or right lymphatic duct (right). Drainage: Entire upper limb.
Anatomy. Anatomically, the subclavian vein is the most anterior vascular structure of the thoracic outlet. It is bound anteriorly by the subclavius muscle and posteriorly by the anterior scalene muscle.
Subclavian vein. (v. subclavia) It begins at the level of the lateral edge of the first rib and passes in front of the anterior scalenus muscle (m. scalenus anterior) to the sternoclavicular joint, behind which it communicates with the internal jugular vein forming the brachiocephalic vein.
