Correlation Between Popliteal Vein Compliance and Venous Clinical Severity Score

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).

Treatment and study plan

Popliteal Vein Compliance

Other

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