Why the study?
Aortic dissection is a rare but serious complication of TAVI that should be considered in the differential diagnosis of acute kidney injury.
Aortic dissection should be considered in the differential diagnosis of acute kidney injury following TAVI, highlighting the importance of careful CT image assessment for early signs.
Post-TAVI AKI warrants aortic dissection consideration; single case extends known complications but leaves practice implications open.
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.
