ABSTRACT

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.
