External iliac artery (Arteria iliaca externa)
Educational content only — not medical advice.
Anatomy
Passes beneath the inguinal ligament at mid-inguinal point to become the femoral artery; it gives the inferior epigastric and deep circumflex iliac branches, and its position defines Hesselbach triangle beneath the commonest inguinal hernia.
Clinical notes
Endurance athletes get inguinal-artery compression syndromes beneath the ligament; pseudoaneurysm after femoral catheterisation forms just below its course and needs thrombin injection or surgery.
