Internal iliac artery (Arteria iliaca interna)
Educational content only — not medical advice.
Anatomy
The mother tree of the pelvis: a posterior trunk (superior gluteal, iliolumbar, lateral sacral) and an anterior trunk (vesical, obturator, middle rectal, uterine/vaginal or inferior vesical, inferior gluteal, internal pudendal) supplying bladder, rectum, genitals and gluteal muscles.
Clinical notes
Internal iliac ligation controls catastrophic pelvic haemorrhage after birth or trauma; post-prostatectomy pseudoaneurysm bleeds recurrent haematuria, and its pudendal branch anchors perineal surgery.
