Correlation Between Popliteal Vein Compliance and Venous Clinical Severity Score

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).

Inclusion Criteria:

• C1 to C6 disease using the CEAP (clinical, etiologic, anatomic, pathophysiologic) classification.

Exclusion Criteria:

• acute or chronic thrombosis of deep veins, previously received intravenous surgery or injection sclerotherapy, ankle brachial index<0.90, and concomitant cardiovascular, pulmonary, renal, or metabolic diseases.
