Chimney grafts (CG) have been used in the repair of juxtarenal aortic aneurysm (JAA) as a pure endovascular approach, which involve the concurrent deployment of an aortic endograft with covered stents in the renal arteries. In the present study, we report a rare but significant complication of chimney grafting in a case of JAA with iliac artery ectasia. During the placement of CG, one of the covered stents was dislodged in a distal branch of the right renal artery, resulting in segmental infarct of the right kidney.
