Summary

When the liquid flow increases, the luminal caliber's stretching amplitude decreases, leading to a higher hydraulic pressure according to Poiseuille's law. In this study, investigators measured the caliber change of the popliteal vein under a rated pressure gradient and evaluated the relationship between popliteal vein compliance and venous clinical severity score (VCSS).

Conditions

• Chronic Venous Disease (CVD), Vein Compliance, Venous Clinical Severity Score (VCSS)

Interventions

Type	Name	Description
OTHER	Popliteal Vein Compliance	Compliance of the popliteal vein is calculated as the distensibility, with the ratio of functional caliber/native caliber/cuff pressure value ( mmHg-1 ).
