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

A retrospective study of patients who underwent thoracic endovascular aortic repair for type-B aortic dissection, comparing those who developed aortic dilatation with those who did not and healthy controls. Computational fluid dynamics simulations were performed on 3D models reconstructed from computed tomography angiography images acquired at multiple time points. The dataset was authored by Qian-hui Tang and is available under a CC-BY-4.0 license.

Use Cases

• Identify hemodynamic risk factors for aortic dilatation based on oscillatory shear index values in the false lumen.
• Compare post-operative pressure changes at arterial branch ostia between patient groups.
• Validate computational fluid dynamics models for predicting surgical outcomes in aortic dissection.

Strengths

• Dataset includes longitudinal computed tomography angiography images from multiple patient groups.
• Computational fluid dynamics simulations provide derived hemodynamic metrics like oscillatory shear index.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 26.7 KB file size suggests the dataset is a document describing the study rather than the raw simulation data.
