Successful stent-graft placement for the treatment of a superior gluteal artery pseudoaneurysm in a patient following complex pelvic surgery.

Aneurysms of the gluteal arteries are rare and were previously managed with open surgical procedures. Recently percutaneous embolisation techniques have helped reduce morbidity and mortality. A case is presented of a 63-year-old man who presented with haemorrhage and had developed a superior gluteal artery aneurysm following treatment for an invasive squamous cell carcinoma in the sacral area. There was concern that embolisation of the aneurysm might compromise the survival of the myocutaneous buttock rotation flaps that had been used for reconstruction. To overcome this, an endovascular stent was deployed to successfully close off the aneurysm whilst at the same time maintaining blood flow through the superior gluteal artery. Aneurysms in larger peripheral vessels have been managed with stents. However, this is the first reported case of this method of treatment being used in the management of gluteal artery aneurysms.
