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

Qian-hui Tang's research dataset investigates hemodynamic factors associated with aortic dilatation following thoracic endovascular aortic repair (TEVAR) for type-B aortic dissection. The dataset includes computational fluid dynamics (CFD) simulation results, such as oscillatory shear index (OSI) and pressure measurements at arterial branch ostia, derived from computed tomography angiography (CTA) images of patient groups. The data was last updated on 2026-04-22.

Use Cases

• Identify hemodynamic risk factors for aortic dilatation based on oscillatory shear index (OSI) values in the false lumen.
• Compare post-operative pressure changes at arterial branch ostia between patient groups.
• Validate computational fluid dynamics (CFD) models for predicting surgical outcomes in type-B aortic dissection.

Strengths

• Data includes CFD simulation results from patient CTA images at multiple time points (pre-TEVAR, 1-week post-TEVAR, follow-up).
• The study design includes a control group (Group F) for comparison.
• Dataset is licensed under CC-BY-4.0 for open sharing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (25.1 KB), indicating limited scope.
