Common iliac artery (left) (Arteria iliaca communis)
Educational content only — not medical advice.
Anatomy
The paired branches of the aortic bifurcation at L4, descending briefly to divide at the sacroiliac joint into external (for the limb) and internal (for the pelvis) iliac arteries; ureters and autonomic plexuses accompany its course.
Clinical notes
Post-aortic-surgery common-iliac aneurysm threatens rupture; acute thrombosis devascularises the whole limb unless urgently revascularised, and chronic ureteric compression hydronephroses the kidney.
