目的　探讨老年高危腹主动脉瘤患者的微创治疗方法。　方法　 18例应用腔内搭桥技术治疗的老年腹主动脉瘤患者 ,动脉瘤分型 :A型 1例 ,B型 11例 ,C型 6例。术前以CT、MR及血管造影检查评估腔内治疗的可行性并测量相关数据 ;设计并选择合理带膜支架 ;取双侧腹股沟小切口 ,在X线透视下将支架通过股动脉放置在腹主动脉瘤的恰当位置上 ,实现动脉瘤腔内搭桥。　结果　18例接受腹主动脉瘤腔内搭桥患者成功率 10 0 %。手术时间 1～ 6h ,平均 (3 40± 0 34 )h。出血量5 0～ 6 2 0ml,平均 (35 0± 10 4)ml。并发症 :内漏血 2例 ,截瘫 1例 ,腹股沟血肿 1例。　结论　动脉瘤腔内搭桥是一种新的微创治疗方法 ,具有创伤小、恢复快、技术操作可行、近期效果肯定的优点 ,尤其适合全身状况不能耐受传统手术的老年患者。但该技术远期疗效有待进一步观察。 Objective To investigate the minimally invasive treatment of elderly patients with high-risk abdominal aortic aneurysm. Methods 18 cases of elderly patients with abdominal aortic aneurysm treated by endovascular embolization were divided into three groups: type A in 1 case, type B in 11 cases and type C in 6 cases. Preoperative evaluation of CT, MR and angiography to assess the feasibility of endovascular treatment and measurement of relevant data; design and select a reasonable stent with a stent; take a small bilateral inguinal incision, under the X-ray stent placed through the femoral artery in the abdomen Aortic aneurysm in the right place, to achieve intracavitary aneurysm bypass. Results 18 cases of patients undergoing abdominal aortic aneurysm bypass with a success rate of 10%. The operation time was 1 ~ 6 h, with an average of (340 ± 0 34) h. Bleeding volume 50 ~ 6 20ml, with an average (35 0 ± 10 4) ml. Complications: internal bleeding in 2 cases, paraplegia in 1 case, 1 case of groin hematoma. Conclusions Aneurysm endovascular graft bypass is a new minimally invasive treatment, which has the advantages of small trauma, rapid recovery, feasible technique operation and positive effect in the near future. It is especially suitable for elderly patients whose general condition can not tolerate traditional surgery. However, the long-term efficacy of the technology remains to be further observed.
