Superior epigastric artery

In human anatomy, the superior epigastric artery is a blood vessel that carries oxygenated blood to the abdominal wall,[1][2] and upper rectus abdominis muscle.[1]

Anatomical terminology

StructureEdit

The superior epigastric artery arises from the internal thoracic artery (referred to as the internal mammary artery in the accompanying diagram).[3][4] It anastomoses with the inferior epigastric artery at the umbilicus.[3] Along its course, it is accompanied by a similarly named vein, the superior epigastric vein.[citation needed]

FunctionEdit

Where it anastomoses, the superior epigastric artery supplies the anterior part of the abdominal wall,[1][2] upper rectus abdominis muscle,[1] and some of the diaphragm.[citation needed]

Collateralization in diseaseEdit

Vascular diseaseEdit

The superior epigastric arteries, inferior epigastric arteries, internal thoracic arteries and left subclavian artery and right subclavian artery / brachiocephalic are collateral vessels to the thoracic aorta and abdominal aorta. If the abdominal aorta develops a significant stenosis and/or blockage (as may be caused by atherosclerosis), this collateral pathway may develop sufficiently, over time, to supply blood to the lower limbs.[5]

Coarctation of the aortaEdit

A congenitally narrowed aorta, due to coarctation, is often associated with a significant enlargement of the internal thoracic and epigastric arteries.[6]
