External iliac artery - wikipedia External iliac artery External iliac artery Bifurcation of the aorta and the right common iliac artery - side view. ( External iliac artery is artery at upper left, seen splitting from common iliac artery at top. ) The relations of the femoral and abdominal inguinal rings, seen from within the abdomen. Right side. ( External iliac artery is large artery at center, and inguinal ligament runs from upper right to lower left. When the artery crosses the ligament, it becomes the femoral artery. ) Details Source common iliac arteries Branches femoral arteries, inferior epigastric arteries Vein external iliac veins Identifiers Latin arteria iliaca externa Dorlands / Elsevier a_61 / 12154552 TA A12. 2.16. 002 FMA 18805 Anatomical terminology ( edit on Wikidata ) The external iliac arteries are two major arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint of the pelvis. They proceed anterior and inferior along the medial border of the psoas major muscles. They exit the pelvic girdle posterior and inferior to the inguinal ligament about one third laterally from the insertion point of the inguinal ligament on the pubic tubercle at which point they are referred to as the femoral arteries. The external iliac artery is usually the artery used to attach the renal artery to the recipient of a kidney transplant.

It travels inferiorly, anteriorly, and laterally, making its way to the lower limb : Branches Branch Description Inferior epigastric artery Goes upward to anastomose with superior epigastric artery ( a branch of internal thoracic artery ). Deep circumflex iliac artery Goes laterally, travelling along the iliac crest of the pelvic bone. Femoral artery Terminal branch. When the external iliac artery passes posterior to the inguinal ligament, its name changes to femoral artery. The abdominal aorta divides to form the `` common iliac arteries '' in the lower abdomen, and these vessels supply blood to the pelvic organs, gluteal region, and legs. Each common iliac artery descends a short distance and divides into an internal and an external branch. 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. Additional images The internal mammary artery and its branches.
