Arteria epigastrica inferior

In human anatomy, inferior epigastric artery refers to the artery that arises from the external iliac artery.

It anastomoses with the superior epigastric artery.

Along its course, it is accompanied by a similarly named vein, the inferior epigastric vein.

These epigastric vessels form the lateral border of Hesselbach's triangle, which outlines the area through which direct inguinal hernias protrude.
