Short-term Curative Effect Of The Distal Restrictive Stent In Endovascular Repair For Stanford Type B Aortic Dissection

Objective:To evaluate the early outcomes of the distal restrictive stent in endovascular repair of Stanford type B aortic dissection.Methods:A retrospective analysis of clinical data of74patients who were diagnosed as Stanford B-type aortic dissection and repair in cavity in the First Affiliated Hospital of Xinjiang Medical University between March2012and April2013.Analysis and comparison of efficacy of the standard endovascular repair and the joint remote restrictive stent of standard endovascular repair in type B aortic dissection.Results:46patients with TEVAR treatment,28patients with EVAR+RS treatment. The incidence of SIDR of standard endovascular repair group was significantly higher than the joint restrictive standard endovascular repair stent group. The proportion of renal insufficiency of EVAR+RS group was significantly greater than the EVAR group during hospitalization (28.6%VS13.0%; P=0.043). The proportion of distal stent of the false lumen complete thrombosis of stent graft group was significantly greater than the full bare-metal stent group. The true lumen plane4(28.3±3.5mm VS30.3±3.4mm, P<0.05) and the true lumen plane7(18.1±6.4mm VS20.1±6.2mm, P <0.05) of EVAR+RS group was significantly expanded.2patients died in EVAR group,1patient died in EVAR+RS group.Conclusion:The near and mid-term effect of the joint restrictive stent Stanford B aortic dissection surgery is better than conventional endovascular repair. The long-term effect remains to be seen.
