The Superior Epigastric Vein and its branches

Anatomy

The superior epigastric vein is a continuation of the internal thoracic vein. It runs downward in the anterior abdominal wall and drains into the vena cava, the body's largest vein. It is accompanied along its course by a similarly named artery, the superior epigastric artery.

Function

The primary function of the superior epigastric vein is to carry deoxygenated blood from the lower part of the anterior abdominal wall and some of the diaphragm back to the heart.

Clinical Significance

The superior epigastric vein can be involved in several medical conditions. For example, it can be affected by varices, which are abnormally dilated vessels with a tortuous course. It can also be used in surgical procedures such as coronary artery bypass grafting.
