TODO - Background: There are a number of stent-grafts in the market, designed to handle difficult anatomies during endovascular aortic repair. The aim of this study is to determine which stent-graft is the most appropriate to accommodate the majority of infra-renal aortic aneurysms cases. An additional aim is to determine what stent-graft characteristics influence the suitability of the stent-graft. Research design and methods: Retrospective cohort study on the suitability of available stent-grafts for infrarenal aneurysm (AAA) repair based on real-life anatomic data. The anatomical characteristics of 235 AAA were measured manually using specialized software. All measurements were compared to the official instructions-for-use (IFU) using a purpose-specific server-side script. The proper function of the script was additionally confirmed. Results: The highest suitability rate was achieved by Medtronic Endurant. The majority of stent-grafts failed to meet the respective AAA anatomy by one IFU characteristic. Stent-grafts that failed by only one IFU characteristic by ≥80% of unsuitable cases tend to have higher suitability rates. Neck dimensions and CIA diameter are the two characteristics significantly influencing the suitability rate. Conclusions: Any stent-graft with high suitability rates should be available off-the-shelf in any vascular department in order to cover the majority of cases. For challenging cases, special advantages of the stent-grafts should be taken under consideration. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.
