Anatomical terminology [edit on Wikidata]

Theexternal iliac arteries are two majorarteries which bifurcate off thecommon iliac arteries anterior to thesacroiliac joint of thepelvis.

The external iliac artery arises from the bifurcation of thecommon iliac artery. They proceed anterior and inferior along the medial border of thepsoas major muscles. They exit thepelvic girdle posterior and inferior to theinguinal ligament.^[1][2] This occurs about one third laterally from the insertion point of the inguinal ligament on thepubic tubercle.^[1] At this point they are referred to as thefemoral arteries.^[1][3]

The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the inguinal ligament in the lower part of the abdomen and becomes the femoral artery.

The external iliac artery is usually the artery used to attach the renal artery to the recipient of a kidney transplant.
