PURPOSE: To describe the percutaneous treatment of a ruptured renal artery aneurysm (RAA) using a stent-graft. CASE REPORT: An 86-year-old woman had sudden onset of right-sided back pain and a swollen left leg. Computed tomography disclosed a right retroperitoneal mass involving the kidney; the inferior vena cava was compressed, with thrombus in the left common iliac artery. There was a suggestion of RAA associated with contrast extravasation. Angiography confirmed a saccular aneurysm of the distal right main renal artery immediately proximal to the first segmental branch. A Jostent peripheral stent-graft was implanted with complete exclusion of the lesion. At 6-month follow-up, the patient remained asymptomatic, but there was a suggestion of in-stent restenosis, which is being followed closely. CONCLUSIONS: In elderly patients who are hemodynamically stable and have aneurysm anatomy that is suitable for stent-graft placement, the endovascular approach may allow rapid and definitive treatment of the hemorrhage.
