Technical success and outcomes using a flexible bifurcated stent graft (Aorfix^TM) in abdominal aortic aneurysms: a...

Introduction: The Aorfix aortic stent graft is a modular device with greater compliance and flexibility. This systematic review aims to assess the evidence regarding the technical success and outcomes of the Aorfix^TM stent graft.Methods: Electronic bibliographic databases were searched. We conducted our review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards.Results: This review of the 442 documented cases of Aorfix^TM EVAR demonstrates assisted technical success to be achieved in 97.7% of cases. The need for unplanned adjunct maneuvers was low at 9.8% and was most commonly required for resolving an intra-operative type I endoleak. The need for secondary intervention in the 1-year follow up period was even lower, at 1.3% in the same eight studies, while Malas et al reports a re-intervention rate of 7.8% at 1-year.Conclusion: The Aorfix^TM device has been used in AAA with highly angulated proximal necks with success, with acceptable short- and midterm results. But larger multi-center comparative studies, and registry data is needed to be to compare the safety of different stent grafts and for optimal graft selection. This will increase the likely number of patients considered suitable for EVAR.
