Abstract

OBJECTIVE: Bridging stentgrafts (BSGs) are one of the primary limiting factors regarding long-term results after fenestrated endovascular aortic repair (fEVAR). This study aims to report for the first time the outcome of a novel BSG called iCover from a national, multicentric retrospective database.

METHODS: A cohort of 58 patients received 212 BSGs for the renovisceral arteries in fEVAR. Patients were followed-up clinically and with computed-tomography angiography. Study end points were mortality, occurrence of complications, technical success of the BSG implantation, defined as successful deployment with vessel patency and absence of type 1c, 3b, and 3c endoleak, and stability over the follow-up.

RESULTS: Three BSG unrelated mortalities (5.1 %), four BSG unrelated major complications (6.8 %) and five minor complications (8.6 %) occurred. The technical success of iCover was 207/212 (97.6 %), target vessel patency was 100 % over a follow-up of 4.0 months, and no late BSG related endoleak was detected. In two cases, the BSG was dislodged from the balloon and could be parked in a safe position without further sequelae (0.9 %).

CONCLUSION: The iCover represents a feasible BSG for fEVAR with an excellent safety profile and technical success rate in the early phase. Prudent post-dilatation and monitoring of the proximal and distal stent ends can potentially further improve outcome. Longer follow-up series are necessary.
