Correlation Between Popliteal Vein Compliance and Venous Clinical Severity Score

December 17, 2023 updated by: Hao Liu
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).
