腔内修复术治疗有症状和无症状的腹主动脉瘤中期结果比较

Comparison of mid-term outcome after EVAR between symptomatic and asymptomatic AAAs

目的比较有症状性腹主动脉瘤(S-AAAs)和无症状性腹主动脉瘤(E-AAAs)腔内修复术后的中期结果。方法对2008年1月至2013年2月符合标准的230例非破裂性腹主动脉瘤腔内修复的患者进行随访。结果共160例患者完成有效随访,总有效随访率为70%,中位随访时间22.7个月。E-AAAs组心血管病患病率高于S-AAAs组(34.4%比11.5%,P=0.02),重症监护时间长于E-AAAs组[(1.26±3.13)d比(0.07±0.40)d,P<0.01]。两组技术成功率和临床成功率均为100%。两组中期死亡率S-AAAs和E-AAAs分别为25%和13.3%(P=0.12)。两组术后36个月生存率分别为81%(95%CI0.72~0.91)比72%(95%CI0.56-0.91)。结论腔内治疗S-AAAs和E-AAAs的中期结果相似。

Objective To compare the mid-term outcomes after endovascular repair of symptomatic abdominal aneurysms (S-AAAs)and elective non-symptomatic AAAs (E-AAAs).Methods A total of 230 non-ruptured AAA patients treated by EVAR who met the inclusion criteria from January 2008 to February 2013 were followed up.Results A total of 160 cases were followed-up,mean follow-up time was 22.7 months.The prevalence of cardiovascular disease in E-AAAs group was significantly higher than that in S-AAAs group.E-AAAs patients had shorter ICU stay time [(1.26±3.13)d vs.(0.07±0.40)d,P < 0.01]compared with S-AAAs patients.The 36 month survival rate was 81%(95%CI 0.72-0.91)vs. 72%(95%CI 0.56-0.91)respectively.Conclusions There is no difference in mid-term outcome between symptomatic AAA and elective non-symptomatic AAA patients treated by EVAR.
