Hemodynamic Factors of Aortic Dilatation After Thoracic Endovascular Aortic Repair

A 25.7 KB dataset from a retrospective study investigating hemodynamic factors associated with aortic dilatation following thoracic endovascular aortic repair (TEVAR) for type-B aortic dissection. The study, authored by Qian-hui Tang and published on figshare in 2026, used computational fluid dynamics (CFD) simulations on 3D models reconstructed from computed tomography angiography (CTA) images. Patient groups included those with and without aortic dilatation post-TEVAR and healthy controls, with CTA images acquired at multiple time points.

Use Cases

• Analyzing the relationship between oscillatory shear index (OSI) in the false lumen and subsequent aortic dilatation based on CFD endpoints.
• Comparing pressure changes at major arterial branch ostia between patient groups with and without aortic dilatation post-TEVAR.
• Investigating hemodynamic patterns from pre-TEVAR to follow-up using 3D models reconstructed from CTA images.

Strengths

• Data is derived from patient-specific 3D models reconstructed from CTA images, providing anatomical detail.
• CFD simulations were performed with a defined primary endpoint (oscillatory shear index at branch ostia).
• Includes longitudinal data with CTA images acquired at multiple time points for patient groups.

Limitations

• The dataset is very small at 25.7 KB, suggesting limited scope or summary-level data.
• Row count and column-level documentation are unknown, limiting suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
