Blinded Computational Hemodynamic Prediction of Long-Term Postoperative Outcomes in Aortic Dissections Treated with Thoracic Endovascular Aortic Repair

Single-center retrospective observational study Key Findings: Six patients with chronic Type B aortic dissection underwent endovascular repair with blinded computational fluid dynamics analysis.Proximal remodeling was predicted with 83% accuracy (PPV 100%, sensitivity 80%).Significant postoperative pressure reduction across the primary tear correlated with successful false lumen thrombosis/remodeling.Take home Message: The combination of preoperative and immediate postoperative patient-specific hemodynamic simulations can reliably predict long-term remodeling after endovascular repair of chronic Type B aortic dissection, supporting their potential use in surgical planning and individualized outcome prediction.
