The first case of atrial fibrillation-related graft kidney infarction following acute pyelonephritis

Abstract

Native renal infarction is uncommon in patients with atrial fibrillation (AF)-related thromboembolism. Graft infarction is also rare, with such cases mostly occurring in the main graft artery postoperatively. To date, there have been no studies of AF-related graft kidney infarction. We herein describe the first case of AF-related graft kidney infarction. The clinical manifestations of this condition mimic and follow those of acute pyelonephritis; therefore, these diseases should be differentially diagnosed as early as possible using lactic dehydrogenase testing and computed tomography. Aggressive treatment with intravascular thrombolysis should be administered, even when the diagnosis is delayed, in order to restore a viable renal function. © 2014 The Japanese Society of Internal Medicine.
