ABSTRACT
OBJECTIVE:
Fenestrated endovascular aneurysm repair (FEVAR) has become one of the standard treatment options for complex abdominal aortic aneurysms (cAAAs) and thoraco-abdominal aortic aneurysms (TAAAs). Despite technological advances in the main endograft design, the lack of dedicated bridging stent-grafts (BSGs) is still the Achilles heel of the procedure. The aim of this study was to evaluate the mid-term outcomes of the BeGraft stent-graft as a dedicated bridging stent for FEVAR and to review the current evidence in literature.METHODS:
Retrospective single center study, including all consecutive FEVARs performed between September 2018 and December 2022 for the treatment of cAAAs and TAAAs with implantation of at least one BeGraft peripheral as the main BSG in one of the target vessels (TVs). Primary endpoints were technical success and TV instability of TV bridged with a BeGraft stent, as well as 30-day mortality and re-intervention rates. Secondary endpoints were follow-up TV instability, re-interventions, and mortality.RESULTS:
A total of 113 patients (93 male, mean age 71.1±9.7) and 440 TV (14 scallops and 426 fenestrations) were included. Of the 440 TV, 406 received primary stenting. Be Grafts were used in 88.9% of these (n=361; celiac trunk [CT]=67, superior mesenteric artery [SMA]=98, right renal artery [RRA]=97, and left renal artery [LRA]=99). The technical success rate was 99.4% (359/361). The 30-day TV instability rate was 0.27% (1/361) with one early renal artery occlusion. During a median follow-up of 20 months (6-32), TV instability rate was 0.8% (3/361). Freedom from TV instability was 99.3%, 98.8%, and 98.8% at 1, 2, and 3 years, respectively.CONCLUSION:
Early-term and mid-term results regarding TV instability are satisfactory and support the use of BeGraft as BSG in FEVAR for cAAAs and TAAAs. CLINICAL IMPACT The findings of the current study show that the use of the BeGraft stent graft as bridging stent in FEVAR is associated with a high technical success and low early and mid-term instability rate and support the standard use as a bridging stent in fenestrated aneurysm repair.
