Hemodynamic Factors of Aortic Dilatation After Thoracic Endovascular Aortic Repair

Computational fluid dynamics (CFD) simulation results from a retrospective study of patients with type-B aortic dissection. The data includes oscillatory shear index (OSI) and pressure measurements at arterial branch ostia from computed tomography angiography (CTA) images at multiple time points. Author Qian-hui Tang published this dataset under a CC-BY-4.0 license on figshare in April 2026.

Use Cases

• Predicting aortic dilatation risk based on oscillatory shear index (OSI) values in the false lumen.
• Analyzing pressure changes at major arterial branch ostia before and after thoracic endovascular aortic repair (TEVAR).
• Training models to correlate computational fluid dynamics (CFD) endpoints with long-term patient outcomes.
• Comparing hemodynamic profiles between patients who developed aortic dilatation and those who did not post-TEVAR.

Strengths

• Dataset includes CFD simulation results derived from 3D models reconstructed from patient CTA images.
• Analysis is based on a multi-group study design with pre- and post-operative time points for comparison.
• The primary CFD endpoint, oscillatory shear index (OSI), is a well-defined hemodynamic metric.

Limitations

• Dataset size is only 27.3 KB, indicating very limited scope or summary-level results.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The retrospective study design may reflect inherent selection bias from the source institution.
