Two-stage Operation for Stanford Type B Acute Aortic Dissection with Renal Blood Flow Reduction

Abstract

We performed an initial emergency axillobifemoral bypass in a patient with a Stanford type B dissection who showed diminished renal blood flow and could thereby avoid the institution of dialysis. After the initial operation, dilatation of the false lumen in the descending aorta caused narrowing of the true lumen, and compression of the left atrium by the wide false lumen resulted in uncontrollable heart failure. Additionally, thoracic endovascular aortic repair was performed, which led to the improvement of cardiac and renal function.
