[Measuring venous pressure with the Doppler technic: standardization of the method]

Area of Science:

• Vascular Medicine
• Diagnostic Ultrasound
• Phlebology

Context:

• Assessing venous pressure is crucial for diagnosing venous disorders.
• Traditional methods may be invasive or less accessible.
• The Doppler ultrasound offers a non-invasive approach to measure venous hemodynamics.

Purpose:

• To evaluate the diagnostic accuracy and clinical utility of Doppler ultrasound for measuring venous pressure.
• To compare Doppler-derived venous pressure with established conditions like varicose veins and post-phlebitic syndrome.
• To establish reference values for venous pressure in normal subjects.

Summary:

• Doppler ultrasound was used to measure standing venous pressure in 6,172 legs.
• Normal subjects showed average pressures of 59 mmHg (posterior tibial vein) and 58 mmHg (long saphenous vein).
• Patients with varicose veins exhibited pressures of 90 mmHg (deep veins) and 96 mmHg (superficial veins).
• Post-phlebitic syndrome cases presented with average pressures of 101 mmHg (deep veins) and 102 mmHg (superficial veins).

Impact:

• The study validates Doppler ultrasound as a credible and useful tool in phlebological practice.
• Findings provide objective pressure data for diagnosing and managing venous diseases.
• This non-invasive method enhances patient care and diagnostic capabilities in venous insufficiency assessment.
