Abstract

Background: Endovascular technology has advanced rapidly in the development of fenestrated endovascular aneurysm repair (FEVAR). Current evidence for endovascular aneurysm repair is limited to infra-renal aortic aneurysms. With increased costs and complexity of FEVAR, its current role is unclear. A national multicentre, cross-disciplinary consensus model was developed to propose indications for FEVAR. Methods: All UK FEVAR centres and a wide selection of high-volume aneurysm treatment centres were invited to participate. The RAND appropriateness methodology was used. Five key steps were undertaken: meta-analysis of current literature; survey of current UK practice; nominal group establishment and definition of key clinical attributes; round 1-online survey of case vignettes; and round 2-nominal group consensus meeting. Results: More than 90 per cent of UK FEVAR centres participated. Literature review showed heterogeneous case series with no clear indications for use of FEVAR. Survey of current practice showed wide variations in aneurysm management. Consensus agreement on the role of FEVAR was achieved in 68·8 per cent of cases. Consensus for FEVAR was agreed in areas of moderate risk from open repair and need for suprarenal clamping, but it was less likely to be indicated in patients aged 85 years or more with 5·5-6-cm aneurysms, or short-necked infrarenal aortic aneurysms. Conclusion: These data record areas of agreement and define the grey area of equipoise. Consequently, guidelines and recommendations can be developed on the indications for FEVAR to inform clinicians, commissioners and health economists.
