Objective: In advanced cases of cervical carcinoma, the tumor may cause massive bleeding requiring blood transfusion. When conservative management is ineffective, internal iliac arterial embolization (IIAE) may be life-saving. Case Report: The case of lumbosacral neuropathy and buttock necrosis that developed after IIAE. The posterior branch of the internal iliac artery gives the superior gluteal artery, ilio-lumbar artery, and lateral sacral artery. It was anticipated that the gluteal necrosis and neuropathy in this case developed due to ischemic damage with the occlusion of the posterior branch of the internal iliac artery by the embolizing agent. The use of selective embolization where nutrition of the posterior branch of internal iliac artery is preserved, will prevent similar complications.
