Preoperative aortography, magnetic resonance imaging, and postoperative computed tomography. a Aortography showing the superior mesenteric artery (SMA) imaged by the well-developed collateral circulation from the celiac artery (CA). Bilateral renal arteriography was delayed. Severe stenosis is observed in the epigastric aorta of the renal artery (arrowhead). b T1 mapping images on visceral MRI shows a slight increase in the T1 value of the left ventricular wall and no fibrosis progression on the left ventricular wall. c Postoperative 3D-CT showing that the descending thoracic aorta-abdominal aorta bypass and bilateral renal artery bypass were patent
