Reintervention Rate after Open Surgery and Endovascular Repair for Nonruptured Abdominal Aortic Aneurysms

In contrast to IFU EVAR group, the RFS and OS rates of non-IFU EVAR group were lower than in the OAR group during mid-term follow-up. Final endoleak was more frequent, and reintervention was more commonly performed in the non-IFU group than in the IFU group. Therefore, performing EVAR in non-IFU situations should be planned carefully.
