Penetrating injuries to abdomen and especially deep gluteal injuries causes vascular and non vascular injuries which necessitates emergency surgery. Surgical management of the penetrating injuries is very difficult, especially exploration of the gluteal region is very difficult. Management of the injury of iliac artery branches is extremelly difficult. Two cases with penetrating injury to the gluteal region in 1998 and 2000 one was operated emergently and the other was operated electivelly. Coil embolization was tried to be performed for elective case but intervention was unsuccsessful. In both cases internal iliac artery was ligatated and aneurism was repaired. There were no complications in postoperative period. In postoperative angiographic controls, aneurism in the internal iliac artery was regressed and there were no vascular complications at this region such as hematoma. Penetrating injuries at gluteal region causes injury to the internal iliac artery branches which seriously necessitates emergency management, internal iliac artery ligation and impairment.
