Hemodynamic Factors of Aortic Dilatation After Thoracic Endovascular Aortic Repair

Qian-hui Tang's research dataset investigates hemodynamic factors associated with aortic dilatation following thoracic endovascular aortic repair for type-B aortic dissection. The dataset likely contains computational fluid dynamics simulation results, including oscillatory shear index and pressure measurements at arterial branch ostia, derived from computed tomography angiography images of patient and control groups. It was last updated on 2026-04-22.

Use Cases

• Identify hemodynamic risk factors for aortic dilatation based on oscillatory shear index values in the false lumen.
• Analyze post-surgical pressure changes at major arterial branch ostia mentioned in the description.
• Compare computational fluid dynamics simulation outcomes between patient groups with and without aortic dilatation.

Strengths

• Dataset includes longitudinal computed tomography angiography images from three distinct time points for the dilatation group.
• Analysis is based on three-dimensional reconstructed models and computational fluid dynamics simulations, suggesting a detailed biomechanical approach.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is 29.9 KB, indicating a very limited scope or summary-level data.
