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 (TEVAR) for type-B aortic dissection. It contains computational fluid dynamics (CFD) simulation results, including oscillatory shear index (OSI) and pressure measurements at arterial branch ostia, derived from patient CTA images. The dataset was last updated on 2026-04-22 and is licensed under CC-BY-4.0.

Use Cases

• Predicting post-TEVAR aortic dilatation risk based on oscillatory shear index (OSI) patterns in the false lumen.
• Analyzing pressure changes at major arterial branch ostia before and after TEVAR procedures.
• Validating computational fluid dynamics (CFD) models of aortic dissection using patient-specific CTA-derived 3D models.

Strengths

• Includes CFD simulation results for a specific clinical outcome (aortic dilatation).
• Compares data across three patient groups and multiple time points (pre-TEVAR, 1-week post-TEVAR, follow-up).
• Defines a primary CFD endpoint (oscillatory shear index at arterial branch ostia) as stated in the methods.

Limitations

• Dataset is very small at 27.3 KB, indicating limited scope.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The description is detailed but the actual data file format is a DOCX, which may not be structured for direct analysis.
