RESUMO
PURPOSE: To report the successful percutaneous treatment of renal artery stenosis that precipitated renal failure following surgical repair of a thoracoabdominal aortic aneurysm (TAAA). METHODS AND RESULTS: A 70-year-old woman with a solitary kidney became anuric 2 hours after urgent repair of a symptomatic true aneurysm of the Carrel patch from an 8-year-old TAAA repair. After medical treatment failed, aortography was performed, identifying complete occlusion of the solitary renal artery. Balloon dilation and implantation of a Palmaz stent restored renal perfusion and improved function. At 6-month follow-up, she was normotensive and her creatinine within normal limits. CONCLUSIONS: Renal artery stenosis or occlusion is a treatable cause of acute renal failure after TAAA repair. Percutaneous treatment options are likely to be better tolerated than surgical revascularization in this patient population.
