Acute Kidney Injury Secondary to Aortic Dissection Following Transcatheter Aortic Valve Implantation: Perspectives from Nephrologists.

Aortic dissection (AD) is a rare but serious complication of transcatheter aortic valve implantation (TAVI) and should be considered in the differential diagnosis of acute kidney injury (AKI). We herein report an older man who developed AKI secondary to Stanford type B AD after transfemoral TAVI. Non-contrast computed tomography (CT) revealed inward displacement of the calcified intima, which is a key early finding. Contrast-enhanced CT confirmed AD extending to the renal artery. As endovascular intervention was not feasible, conservative management was selected. Nephrologists should recognize AD as an important cause of AKI following TAVI and carefully assess CT images for early subtle signs.
