Patient Specific Changes in Aortic Haemodynamics Are Associated with Thrombotic Risk After Fenestrated Endovascular Aneurysm Repair with Large Diameter Endografts

Objective: The long term durability of fenestrated endovascular aneurysm repair (fEVAR) is threatened by thrombotic complications.1,2 Previous studies have shown a differential risk of adverse events associated with implantation of large diameter fEVAR endografts.3 This study sought to use patient specific computational fluid dynamic (CFD) simulation to investigate the effect of endograft diameter on haemodynamics after fEVAR and explore the hypothesis that diameter dependent alterations in aortic haemodynamics predict future thrombotic events.
