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.
