Hemodynamic Factors of Aortic Dilatation After Thoracic Endovascular Repair

A retrospective study comparing hemodynamic factors in patients with and without aortic dilatation following thoracic endovascular aortic repair (TEVAR) for type-B aortic dissection. Computational fluid dynamics simulations were performed on computed tomography angiography images from patient groups at pre-TEVAR, 1-week post-TEVAR, and follow-up time points. The dataset was authored by Qian-hui Tang and published on figshare in April 2026.

Use Cases

• Analyze associations between oscillatory shear index (OSI) and aortic dilatation based on CFD endpoint data
• Compare pressure changes at arterial branch ostia across different post-operative time points
• Investigate hemodynamic patterns in false lumen versus true lumen following TEVAR

Strengths

• Data includes measurements from three distinct patient groups (dilatation, non-dilatation, healthy control)
• Computational fluid dynamics simulations provide derived hemodynamic metrics
• Images were acquired at multiple time points for longitudinal comparison

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is very small (32.5 KB), indicating limited scope
