What is the left innominate vein?

The left and right brachiocephalic veins (or innominate veins) are major veins in the upper chest, formed by the union of each corresponding internal jugular vein and subclavian vein. This is at the level of the sternoclavicular joint. The left brachiocephalic vein is nearly always longer than the right.

Where is the left innominate vein?

The brachiocephalic veins also referred to as the innominate veins, are large venous structures located within the thorax and originate from the union of the subclavian vein with the internal jugular vein. The left and right brachiocephalic vein join to form the superior vena cava on the right side of the upper chest.

What is Retroaortic innominate vein?

The retro-aortic left brachiocephalic vein is a rare vascular variant where the left brachiocephalic vein passes more inferiorly through the superior mediastinum, coursing inferior to the aortic arch and posterior to the ascending aorta to join the right brachiocepahilc vein forming the superior vena cava.

Is there a right innominate vein?

The right and left innominate veins terminate in the superior vena cava, which opens into the upper posterior portion of the right atrium.

What does the innominate vein do?

Brachiocephalic vein (Innominate vein) The brachiocephalic vein, also known as the innominate vein, is a paired vein of the superior mediastinum that drains the venous blood from the head and neck, upper limbs and the upper part of the thorax.

Is the innominate vein a deep vein?

A deep vein in the lower limb that accompanies the posterior tibial artery; the vein drains the region supplied by the artery.

Is innominate vein a deep vein?

A deep vein in the lower limb that accompanies the posterior tibial artery; the vein drains the region supplied by the artery. The posterior tibial vein merges with the anterior tibial vein to form the popliteal vein in the popliteal fossa behind the knee.

Does the innominate vein have a valve?

The average distance from the valve to the junction with the innominate vein was 1.7 cm for the subclavian vein and 0.3 cm for the internal jugular vein. Valves were bicuspid in 347 (90%) and unicuspid in 39 (10%); unicuspid valves were more common in the internal jugular vein than in the subclavian vein.

Is brachial vein a DVT?

Deep vein thrombosis of the upper extremity (DVT-UE) can occur in any of the veins of the upper extremity or thoracic inlet. These include the jugular, brachiocephalic, subclavian, and axillary veins as well as the more distal brachial, ulnar, and radial veins.

What does the innominate artery do?

The brachiocephalic artery, brachiocephalic trunk, or more commonly referred to clinically as the innominate artery, is one of the three great vessels of the aortic arch that supplies blood to the head, neck and upper extremities.

What is innominate artery stenosis?

Innominate artery disease is caused by a buildup of plaque inside the walls of the artery. The innominate artery brings blood to your right arm, head, and neck. It’s the first branch from the aortic arch that carries blood away from the heart. A blockage slowing blood flow in this artery can put your life at risk.
