Popis: INTRODUCTION: The Abdominal aortic aneurysm (AAA) module of the Portuguese National Vascular Registry (RNPV) is a prospective, voluntary, population-based registry, that encompasses more than 90% of portuguese vascular departments. The aim of this study was to evaluate the results of the first 1000 infra-renal AAA included in the Portuguese RNPV. METHODS: Data were collected from November 2019 to December 2022 and analyzed for demographic aspects, treatment indication, aneurysm anatomic characteristics, type of intervention (EVAR and open surgical repair - OSR), outcome at 30-days and 1-year. EVAR and OSR were compared within elective and urgent settings. RESULTS: A total of 1122 patients were included in the period of study. After applying the exclusion criteria, we analyzed the first consecutive 1000 patients with infra-renal aneurysm submitted to EVAR or OSR, in elective or urgent settings. Elective procedures were perfomed in 79.2% of cases. Patients were predominantly male (91.8%), with a mean age of 74.1 ± 10.6 years. The overall 30-day mortality was 2.7% (EVAR 1.8% and OSR 5.9%; p=0.003). Pos- operative complications were more frequent in the OSR group, with significant repercussion in hospital length, reinterventions and early mortality. Baseline AAA diameter was identified as a predictor of 30-day mortality. Intra- hospital mortality was inversely related with the caseload of the center (p=0.032), mainly due to higher mortality in OSR (p=0.04). The center caseload did not impact the intra-hospital mortality in elective standard EVAR procedures. Urgent repair was performed in 205 patients with significantly larger AAA-diameter (70.5 ± 21.5 mm versus 57.5 ± 14.3 mm, p
