Aim. There are few published studies measuring the hemodynamic effects of different pressures of medical compression stockings. The aim of our study was to measure using duplex ultrasound the effects of stockings on the hemodynamics within varicose veins of the leg.
Methods. The reflux in eight incompetent great saphenous veins has been studied by Duplex using the manual calf squeeze-release maneuvers. Baseline information has been recorded with no stockings in place. Then, three 30-35 mmHg below-knee stockings were applied sequentially: one and then two and then three. After each stocking has been added to the leg, a duplex examination for venous reflux was performed, measuring reflux in the great saphenous vein at the junction of the upper and middle thirds of the thigh.
Results. During this observational study it became evident that flux and reflux have decreased progressively. When the three medical compression stockings were put on in superimposition (maximum 90-100 mmHg), amplitudes and durations of reflux curves shortened and disappeared in three of eight cases.
Conclusion. With sequential increases in pressure using medical compression stockings, the flux and reflux decrease. They almost completely disappear when the applied pressure is about 100 mmHg. In practice it should be possible to determine an ideal externally applied pressure which eliminates venous reflux completely in a set of varicose veins. If that is the case, such a situation may stop the evolution of the varicose vein disease in that patient, using this simple treatment: Medical Compression Stockings with high pressure.
