Epigastric veins

Epigastric veins

The epigastric veins, as illustrated in Gray's Anatomy.

The epigastric veins are a network of blood vessels that drain the abdominal wall and pelvis. They are part of the systemic circulation, which carries oxygenated blood from the heart to the body's tissues and returns deoxygenated blood back to the heart.

Anatomy

The epigastric veins are divided into two main branches: the superior epigastric vein and the inferior epigastric vein. The superior epigastric vein drains the upper part of the abdominal wall, while the inferior epigastric vein drains the lower part.

The superior and inferior epigastric veins.

Function

The epigastric veins play a crucial role in the venous return of blood from the abdominal wall and pelvis to the heart. They also serve as important collateral circulation pathways in conditions that obstruct the inferior vena cava or portal vein.

Clinical significance

Abnormalities of the epigastric veins, such as varices or thrombosis, can lead to serious medical conditions. They are also important landmarks in various surgical procedures, including laparoscopic surgery and abdominal wall reconstruction.
