Acute Embolic Occlusion of Renal Artery after the Bentall Procedure: the Role of Primary Renal Angioplasty.

Abstract

Acute renal occlusion is an uncommon emergency problem in daily practice. The diagnosis is often missed or delayed not only because of its rarity but also nonspecific of clinical presentation. Sudden and complete termination of arterial blood supply to the kidney may lead to renal infarction and a complete loss of renal function. Although the need of early revascularization is uniformly recommended, but the methods has not been established. We presented a case of acute thromboembolic renal artery occlusion in patient who had a history of Bentall's surgery. Renal infarction and artery occlusion were clearly visualized by computed tomography angiogram (CTA). The patient was successfully treated with angioplasty and stenting of main renal artery with complete disappearance of symptoms and recovery of his renal function.
