External iliac artery
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
The external iliac artery is a large artery in the pelvic region that carries blood to the lower limb.
The external iliac artery is a paired artery, meaning there is one on each side of the body: a right external iliac artery and left external iliac artery.
The external iliac artery arises from the bifurcation of the common iliac artery. It travels inferiorly, anteriorly, and laterally, making its ways to the lower limb:
| 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 external iliac artery is accompanied by the external iliac vein, which is located posterior to the artery.
