国产覆膜支架治疗Stanford B型主动脉夹层

目的评价国产主动脉覆膜支架治疗Stanford B型主动脉夹层患者的院内及中期临床疗效。方法应用国产覆膜支架行主动脉腔内隔绝术治疗B型主动脉夹层患者34例,经股动脉置入覆膜支架封堵胸主动脉破裂口,置入Aegis或Hercules国产支架后,造影检查证实疗效。术后平均随访(19±17)个月。结果34例手术均获成功。32例置入1枚支架,2例分别置入主体和短支架各1枚,平均支架直径(33.5±3.5)mm,平均支架长度(96.5±17.6)mm。1例术后2h死于夹层破裂。3例术后存在原发性内漏。2例肾功能不全。出院后随访,2例分别于术后5个月和9个月发生继发性内漏,1例1年时升主动脉再次发现夹层,1例6个月后发生截瘫,2例死亡。结论国产主动脉覆膜支架治疗Stanford B型主动脉夹层患者具有良好的临床疗效。

Endovascular repair of type B aortic dissection using China-made stent

Objective To evaluate results of endovascular repair of type B aortic dissection by China-made stent implantation.Methods Thirty-four patients with type B aortic dissection underwent implantation of China-made stent.All patients were followed up for(19±17)months.The devices used included Aegis or Hercules China-made stents.Results Thirty-two cases were implanted with one main stent and 2 cases with both main and cuff stents.The average diameter of the stents was(33.5±3.5)mm and the length was(96.5±17.6)mm.Primary technical success was achieved in all patients.Major complications included 3 cases of primary endoleak,1 in-hospital death and 2 acute renal insufficiency.Secondary endoleak occurred in 2 patients during follow-up period.After three months,CT scan documented widely patent stent grafts and complete thrombosis of the false lumen in all patients,no evidence of migration or twisting of the stent-graft was noted.Ascending aortic dissection occurred in one patient after one year.Two patients died within the follow-up period.Conclusions In-hospital and mid-term results showed that the China-made stent graft was effective in treatment of acute type B aortic dissection.
