The application of individual open fenestrated stent graft in type A aortic dissection / 实用医学杂志

ABSTRACT

Objective To observe the recent clinical effect of application of individual open fenestrated stent graft in type A aortic dissection without developing the greater curve of the arch. Method From December 2014 to November 2016,15 patients of type A aortic dissection without developing the greater curve of the arch un-derwent endovascular total arch replacement using individual open fenestrated stent graft in the Anhui Province Hospital.Among them,8 cases were only operated with open fenestrated stent graft in aortic arch, 7 cases with open fenestrated stent graft in aortic arch added 1 or 2 small stent graft.Result There was 1 postoperative death caused by severe low cardiac output. The rest of the patients were successfully discharged from the hospital, without ner-vous system and related complications. Follow-up computerized tomographic angiography showed all implanted stents were wide expansion and in a good position. No endoleaks and thrombus obliterated of the corresponding false lumen was found. Conclusion Individual open fenestrated stent graft is suitable for type A aortic dissection without developed the greater curve of the arch.Its significantly simplify the total arch replacement operation steps, reduce anastomotic and shorten the lower body arrest time. Consequently, reduce the risk of operation difficulty, postoperative blood loss and other viscera damage probability significantly. The early and middle term clinical re-sults is satisfactory.
