Abstract

Aim: This study aimed to compare the differences in perioperative outcome after endovascular repair of symptomatic abdominal aneurysms (S-AAAs) and elective non-symptomatic AAAs (E-AAAs). Data from the ENGAGE Registry were used for the analysis. Methods: Between March 2009 and December 2010, 1200 AAA patients were enrolled from 79 sites in 30 countries and treated with an Endurant Stent Graft. S-AAAs defined as AAAs accompanied by abdominal or back pain, without rupture, were present in 185 (15.4%) patients and E-AAAs in 1015 (84.6%) patients. Multivariate logistic regression was used to compare results. Results: At baseline, E-AAA patients had larger aneurysms on average (P = 0.006) and scored higher ASA classification more often (P = 0.001). Further analyses were corrected for baseline differences. Operation time and technical success were comparable, and S-AAAs were admitted to the Intensive Care Unit (ICU) as often as E-AAAs (35.7% vs. 33.4%, P = 0.479). Post-operative hospitalisation was similar (4.83 +/- 5.29 in E-AAAs and 4.37 +/- 3.49 in S-AAAs, P = 0.360). No differences in the occurrence of major adverse events, including mortality, within the 30-day post-implantation were seen between S-AAA and E-AAA patients, respectively, 3.2% and 4.2% (P = 0.572). Conclusion: With contemporary devices and technical proficiency, there is no difference in outcome between symptomatic AAA and elective non-symptomatic AAA patients if treated with endovascular techniques.
