[Pseudoaneurysm of the gluteal artery: 2 case reports].

Abstract

According to our knowledge, only 8 cases of gluteal artery pseudoaneurysms are reported in literature in the last 11 years (including the first three months of this year) [4-8]. The lesions of the gluteal arteries, especially pseudoaneurysms, have no specific symptoms and signs. usually, they appear as haematoma pulsans and neurologic deficiency due to compression. (One of our patients). The gluteal abscess can be a differential diagnostic problem. Duplex ultrasonography, CT and selective angiography can be used in the diagnosis [5]. The standard surgical treatment of gluteal artery pseudoaneurysms consists of the ligature of the internal iliac artery (using transperitoneal or extraperitoneal approach) and pseudoaneurysmal resection and ligation of nutrient vessels by gluteal approach [9]. The second procedure is the temporary clamping of the internal iliac artery and transgluteal ligation of the nutrient vessels [7]. The microcatheter embolization of the nutrient vessels using standard invasive radiologic approaches via femoral artery is the method of choice in the treatment of gluteal artery pseudoaneurysms [10]. A buttock pulsatile mass and neurological deficiency in a patient with history of penetrating gluteal trauma, suggest the existence of gluteal artery pseudoaneurysm and require diagnostic evaluation.
