摘要
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。
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 followup 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 stentgraft 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.
