Inferior Epigastric Artery

The Inferior Epigastric Artery and its branches (shown in red).

The Inferior Epigastric Artery is an artery that supplies blood to the lower part of the anterior abdominal wall and some of the pelvic organs. It is a branch of the external iliac artery and runs upward on the inside of the abdominal wall to the level of the umbilicus.

Origin and Course

The Inferior Epigastric Artery originates from the external iliac artery just above the inguinal ligament. It ascends obliquely upward and medially, behind the transversalis fascia and the rectus abdominis muscle, up to the umbilicus.

Branches and Supply

The Inferior Epigastric Artery gives off several branches which supply the lower part of the anterior abdominal wall, the peritoneum, and the lower part of the rectus abdominis muscle. It also anastomoses with the superior epigastric artery and the lower intercostal arteries.

Clinical Significance

The Inferior Epigastric Artery is of clinical importance in several surgical procedures, including hernia repair and flap surgery. It is also used as a landmark in laparoscopic surgery.
