ABSTRACT
OBJECTIVE:
Assess subsequent cardiovascular events and all-cause mortality in patients with intact AAA treated by EVAR according to the existence of isolated EL2 at 1 year after EVAR implantation.METHODS:
This retrospective, single-centre study included patients treated with EVAR between 2010 and 2017 in the vascular surgery department of the University Hospital of Lyon with a infrarenal AAA > 50 mm. The baseline clinical characteristics collected just before EVAR were retrieved from electronic patient records of our institution. AAA characteristics, procedure and the one-year post-operative CTA were reported. Study endpoints, major adverse cardiovascular events (MACE), major adverse lower extremity events (MALE) and all-cause mortality, were recorded during follow-up. Patients were divided into 2 groups according to the presence of isolated EL2 (EL2 +) or absence (EL2 -) of any endoleak on CTA at 1 year. MACE, MALE and all-cause mortality were compared between both groups.RESULTS:
During the study period, 589 patients were treated by endovascular surgery and 207 were included. According to the CTA results at 1 year, 60 patients (29%) were included in the EL2 + group, and 147 patients (71%) in the EL2 - group. A total of 109 patients (53%) experienced a MACE or MALE; significantly fewer patients in the EL2 + than in the EL2 - group did so (p = .009). There were 47 patients (23%) who experienced at least one MALE, and the frequency was significantly lower in the EL2 + group (p = .017).CONCLUSION:
Patients with AAA treated by EVAR who did not develop EL2 at one year, were at higher risk of MALE during follow-up. This might be explained by more frequent symptomatic LEPAD at baseline in this group. These patients therefore require a closer follow-up and strict control of cardiovascular risk factors to prevent cardiovascular morbi-mortality.
