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 computed tomography angiography (CTA) images of patients and healthy controls. The dataset is 25.7 KB in size and was last updated on 2026-04-22.

Use Cases

• Predicting aortic dilatation risk based on oscillatory shear index (OSI) values in the false lumen.
• Analyzing post-TEVAR pressure changes at major arterial branch ostia to identify hemodynamic patterns.
• Training models to correlate computational fluid dynamics (CFD) simulation outputs with clinical outcomes in aortic dissection.

Strengths

• Dataset includes CFD simulation results from patient CTA images at multiple time points (pre-TEVAR, 1-week post-TEVAR, and follow-up).
• Specific hemodynamic endpoints are defined, such as oscillatory shear index (OSI) at arterial branch ostia.
• Data is licensed under CC-BY-4.0, allowing for open reuse and sharing.

Limitations

• The dataset is very small at 25.7 KB, indicating limited scope.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The description does not specify the number of patients or controls included in the study.
