Internal Thoracic Vein

The Internal Thoracic Vein (also known as the Internal Mammary Vein) is a vein that runs parallel to the Internal Thoracic Artery. It is responsible for draining the anterior thoracic wall and the upper part of the abdominal wall.

Anatomy

The Internal Thoracic Vein originates from the superior epigastric vein and the musculophrenic vein. It runs along the inner surface of the anterior thoracic wall, parallel to the Internal Thoracic Artery. It drains into the Brachiocephalic Vein.

Function

The main function of the Internal Thoracic Vein is to drain the anterior thoracic wall and the upper part of the abdominal wall. It also serves as a pathway for blood to return to the heart.

Clinical Significance

The Internal Thoracic Vein is often used in Coronary Artery Bypass Grafting (CABG) surgery. It is harvested and used as a conduit to bypass blocked coronary arteries. This vein is preferred due to its size, length, and ease of harvest.
