title: Pseudoaneurysm of the superior gluteal arterial system: an unusual cause of pain after a pelvic fracture.
abstract: This case report describes a complication after treatment of a rotationally unstable pelvic fracture: a pseudoaneurysm of the superior gluteal arterial system. The patient sustained an anterior-posterior compression pelvic fracture that was stabilized with anterior symphyseal plating and percutaneous iliosacral screw insertion. The etiology of the pseudoaneurysm was likely multifactorial, including the injury (anterior-posterior compression pelvic fracture), prolonged coagulation parameters during administration of warfarin, and the percutaneous insertion of an iliosacral lag screw. A pseudoaneurysm of the superior gluteal arterial system should be included in the differential diagnosis of unexplained pelvic or buttock pain after a pelvic fracture.
