ORIGIN: Left common iliac artery


COURSE/DISTRIBUTION: The left external iliac artery arise from the left common iliac artery its termination in front of the sacroiliac joint. It runs immediately downwards and forwards along the medial border of psoas major. At the mid-inguinal point on the inguinal ligament (i.e. midway between the anterior superior iliac spine and pubic tubercle, it enters the thigh under the inguinal ligament to become the femoral artery. It lies on the parietal peritoneum that separates it from the appendix and the terminal ileum. It is crossed by the ureter, the gonadal vessels, genital branch of genitofemoral nerve, the deep circumflex iliac vein and the ductus deferens in the male (and round ligament of the uterus in the female). Posteriorly, it lies on the iliac fascia that separates it from psoas major and its medial border.



  • Right inferior epigastric artery
  • Right deep circumflex iliac artery
  • Right femoral artery which is its continuation
  • Right superficial circumflex iliac artery
  • Right superficial epigastric artery
  • Right superficial external pudendal artery


The last three branches mostly arise from the femoral artery.
