Patient-Specific CFD Analysis of Internal Jugular Vein Stenosis

Five patient cases with non-thrombotic internal jugular vein stenosis were analyzed using computational fluid dynamics derived from CT venography. The study quantifies segment-specific hemodynamic patterns, including trans-stenotic pressure gradients and wall shear stress. It was authored by Hui Li and published in 2026.

Use Cases

• Analyze trans-stenotic pressure gradients against stenosis severity to quantify hemodynamic impact.
• Model patient-specific wall shear stress and high-velocity jet patterns within narrowed J1-J3 vein segments.
• Compare hemodynamic metrics and venous morphology outcomes for J3 stenoses before and after decompression.
• Correlate clinical features and lesion morphology with segment involvement (J1, J2, J3) and etiology.

Strengths

• Includes five patient-specific computational fluid dynamics models for cross-case comparison.
• Quantifies specific hemodynamic metrics like pressure gradients and wall shear stress.
• Published in 2026, ensuring contemporary clinical and methodological relevance.

Limitations

• Small sample size of five patient cases limits statistical power and generalizability.
• Data is contained within a single 1.9 MB DOCX file, requiring manual extraction for computational analysis.
• Retrospective study design may introduce selection bias.
