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

A 20.2 KB dataset from a retrospective study investigating hemodynamic factors linked to aortic dilatation following thoracic endovascular aortic repair (TEVAR). Computational fluid dynamics simulations were performed on 3D models reconstructed from computed tomography angiography images across patient groups. The dataset, authored by Qian-hui Tang and licensed under CC-BY-4.0, was last updated on April 22, 2026.

Use Cases

• Analyzing the relationship between oscillatory shear index (OSI) in the false lumen and aortic dilatation risk.
• Comparing pressure changes at major arterial branch ostia between pre- and post-operative time points.
• Investigating hemodynamic differences between patients who developed aortic dilatation and those who did not after TEVAR.

Strengths

• Data is derived from computational fluid dynamics simulations on patient-specific 3D models.
• Includes measurements from multiple time points: pre-TEVAR, 1-week post-TEVAR, and follow-up.
• Explicitly compares a dilatation group, a non-dilatation group, and a healthy control group.

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 at 20.2 KB, indicating limited scope.
