Overview
Late endovascular abdominal aneurysm repair (EVAR) complications not amenable to endovascular correction can undergo either late open conversion (LOC) or semi-conversion (SC).
LOC is defined as a total or partial endograft explantation >30 days after the initial EVAR.
SC is defined as open or laparoscopic surgery for endoleak (EL) correction with complete endograft preservation.
The aim of this study is to collect in a prospective database the technical aspects of a multicenter experience of LOC and SC, and to analyse early and long-term outcomes of these two treatments.
Eligibility
Inclusion Criteria:
- open or laparoscopic surgery for EVAR complications, with or without endograft explantation
Exclusion Criteria:
- endovascular reinterventions
- extra-anatomical bypass surgery (e.g. femoro-femoral crossover bypass) not associated with direct aorta/endograft surgery
