Late post-EVAR abdominal aortic aneurysm rupture: a meta-analysis study

Abstract

This study presents updated information on post-endovascular aneurysm repair (EVAR) late aortic rupture (LAR) as the data in the literature are limited. It comprises a meta-analysis based on the recent evidence regarding the incidence, causes, treatment outcomes, and prognosis of post-EVAR. A meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies were identified by searching electronic databases and scanning bibliographic references from 1991 to April 1, 2023. Our analysis provided evidence that the most common causes of rupture after EVAR were type Ia and Ib Endoleaks (Els). Post-rupture mortality after EVAR was high (35.6%) and comparable to the morbidity of de novo ruptures. Endovascular repair appears to have better results compared to conversion to open repair. A significant number of patients had prior endovascular reoperations and inadequate follow-up. Patient compliance with the surveillance protocol is mandatory.
