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

Qian-hui Tang's retrospective study investigates hemodynamic factors linked to aortic dilatation following thoracic endovascular aortic repair for type-B aortic dissection. It includes computational fluid dynamics simulations derived from computed tomography angiography images of patients and healthy controls. The dataset was last updated on April 22, 2026.

Use Cases

• Analyzing the relationship between oscillatory shear index in the false lumen and post-operative aortic dilatation.
• Comparing pressure changes at major arterial branch ostia before and after thoracic endovascular aortic repair.
• Modeling hemodynamic changes using computational fluid dynamics simulations based on patient CT angiography.

Strengths

• Data includes patient groups with aortic dilatation, without dilatation, and healthy controls.
• Computational fluid dynamics simulations were performed on 3D models reconstructed from CT angiography.
• The dataset is licensed under CC-BY-4.0, allowing for open reuse.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
