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

Qian-hui Tang's dataset investigates hemodynamic factors linked to aortic dilatation following thoracic endovascular aortic repair for type-B aortic dissection. It contains computational fluid dynamics simulation results, including oscillatory shear index and pressure measurements at arterial branch ostia, derived from computed tomography angiography images of patient and control groups. The dataset was last updated on 2026-04-22 and is licensed under CC-BY-4.0.

Use Cases

• Identify hemodynamic predictors of aortic dilatation based on oscillatory shear index in the false lumen.
• Compare post-operative pressure changes at major arterial branch ostia between patient groups.
• Validate computational fluid dynamics models for aortic dissection using clinical imaging data.

Strengths

• Data is derived from computed tomography angiography images and 3D model reconstructions.
• Includes measurements from multiple patient groups at defined time points (pre-TEVAR, 1-week post-TEVAR, follow-up).
• Primary endpoint is a defined computational fluid dynamics metric: 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.
• Dataset is very small at 29.7 KB, indicating limited scope.
