Effect of thoracic endovascular aortic repair on renal artery blood supply and renal function in type B aortic dissection patients
Abstract：Objective To study the effect of thoracic endovascular aortic repair (TEVAR) on renal artery blood supply and renal function in type B aortic dissection patients .Methods One hundted and ten B type aortic dissection patients were divided into ⅠA group (with dynamic ischemia of bi-lateral renal arteries ,n=10) ,ⅠB group (with static ischemia of unilateral renal artery ,n=36) ,ⅠC group(with static ischemia of bilateral renal arteries ,n=34)according to the involved renal arteries in male patients ,and intoⅡA group(without involvement of bilateral renal arteries ,n=20) ,ⅡB group (with involvement of unilateral renal artery ,n=38) ,ⅡC group(with involvement of bilateral renal arteries ,n=34) according to the involved renal arteries in female patients .Ische-mia in bilateral renal arteries and renal function before and after operation were observed and compared .Results Of the 220 renal arteries ,42 (19 .1% ) had dynamic ischemia and 80 (36 .4% ) had static ischemia .Both dynamic and static ischemia were improved after operation .The renal function progressively dcereased in male or female patients with the involvement of their renal ar-teries .Conclusion Thoracic endovascular aortic repair can enlarge the aortic lumen ,improve the renal artery blood supply and renal function in type B aortic dissection patients .
