title: Pseudoaneurysm of the inferior gluteal artery following polytrauma: diverse presentation of a dangerous complication: a report of two cases.
abstract: Gluteal artery aneurysms are rare, and the majority of them are pseudoaneurysms secondary to blunt or penetrating trauma. The superior gluteal artery is normally affected. Inferior gluteal artery pseudoaneurysms are uncommon, and review of the literature revealed only 10 cases in the last 30 years. The mainstay of diagnosis is angiography, but these aneurysms may not be visible on an aortic flush angiogram, and super selective angiography may be required to delineate the anatomy. Treatment is either by surgical therapy or minimally invasive techniques, such as embolization, during angiography. We report two cases of pseudoaneurysms of the inferior gluteal artery following pelvic and acetabular trauma, presenting very differently in time and clinical picture. A review of the relevant literature is also presented.
