Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Intraprosthetic thrombus (IPT) formation and its progression to limb graft occlusion (LGO) are significant complications following endovascular aneurysm repair (EVAR). Morphological metrics based on preoperative CTA have limited predictive value for these complications. This study aims to assess the potential of computational fluid dynamics (CFD) in predicting IPT formation and its progression to LGO after EVAR.
