Inferior epigastric artery

The inferior epigastric artery (latin: arteria epigastrica inferior) arises from the external iliac artery behind the inguinal ligament.

The inferior epigastric artery curves forwards and passes obliquely upwards along the medial margin of the deep inguinal ring, where it continues as an artery of the anterior abdominal wall.

The inferior epigastric artery gives off several side branches:

  • pubic branch,
  • cremasteric artery (for male),
  • artery of round ligament of uterus (for female).

There is also an anastomosis formed between the inferior epigastric artery and the superior epigastric artery (from the internal thoracic artery).

The inferior epigastric artery supplies blood to the muscles of the anterior abdominal wall, such as the rectus abdominis muscle, and to the deep abdominal wall of the pubic and the lower umbilical regions.
