The external iliac artery (EIA) is the larger of the two terminal branches of the common iliac artery (CIA).
Gross anatomy
Origin
The common iliac artery bifurcates into the internal iliac artery and external iliac artery at the level of the pelvic brim anterior to the sacroiliac joint.
Course
The external iliac artery courses medially along the iliopsoas muscle 1. After it enters the thigh under the inguinal ligament, it changes name and continues as the common femoral artery, supplying the lower limb.
Branches
Relations
- anteriorly (at origin): gonadal arteries and veins, genital branch of the genitofemoral nerve, deep circumflex iliac vein, round ligament 1
- posteriorly: iliac fascia, psoas muscle 1
