Hemodynamic Factors of Aortic Dilatation After TEVAR for Type-B Aortic Dissection

A retrospective study of patients who underwent thoracic endovascular aortic repair (TEVAR) for type-B aortic dissection, comparing those who developed aortic dilatation with those who did not and healthy controls. Computational fluid dynamics simulations were performed on 3D models reconstructed from computed tomography angiography images to analyze pressures and oscillatory shear index at arterial branch ostia. The dataset was authored by Qian-hui Tang and is available under a CC-BY-4.0 license, last updated on 2026-04-22.

Use Cases

• Analyzing the relationship between false lumen oscillatory shear index and aortic dilatation risk based on CFD simulation results.
• Comparing pre- and post-operative hemodynamic pressures at major arterial branch ostia across patient groups.
• Investigating the association between early post-TEVAR true lumen pressure reduction and subsequent aortic dilatation trends.

Strengths

• Includes data from multiple patient groups (dilatation, non-dilatation, healthy control) at defined time points.
• Analysis is based on 3D models from computed tomography angiography and computational fluid dynamics simulations.
• Specific hemodynamic endpoints are defined, such as oscillatory shear index at arterial branch ostia.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (16.8 KB), indicating limited scope, likely containing summary results rather than raw simulation data.
