Objectives The purpose of this pilot study was to examine and compare the effects of graduated compression stockings, local vibration, and combined graduated compression stockings and local vibration on popliteal venous blood velocity. Method Twenty-four healthy subjects received four 15 min interventions (control, graduated compression stockings alone, local vibration alone, and combined graduated compression stockings and local vibration), while resting inactive in the prone position. Popliteal vein blood velocity was investigated before (PRE) and at the end (POST) of each intervention using Doppler ultrasound. Results At POST, peak velocity was reported to be 26.3 ± 53.5% ( p <  0.05) greater for local vibration than control (CONT). Peak velocity was 46.2 ± 54.6% ( p <  0.001) and 21.1 ± 37.6% ( p <  0.01) higher for graduated compression stockings than CONT and local vibration, respectively. Graduated compression stockings + local vibration presented 64.1 ± 58.0% ( p <  0.001), 38.4 ± 52.4% ( p <  0.001) and 15.0 ± 31.6% ( p <  0.05) greater values than CONT, local vibration and graduated compression stockings, respectively. Conclusions This study demonstrated an increase in popliteal venous blood velocity after graduated compression stockings and local vibration application. Their combination provided the greatest effects.

SummaryThe effects of graduated compression stockings (GCS) on venous blood velocity have not been established. In healthy subjects, most investigations showed no effect on blood velocity, but mixed results have been reported. In this investigation we to test the hypothesis that popliteal blood velocity is increased by properly fitted GCS. Time average peak velocity in the popliteal vein, as well as time average mean velocity, vein diameter and mean volumetric flow were measured by pulsed wave Doppler ultrasound in 25 healthy male volunteers without compression stockings and repeated with fitted thigh-length compression stockings. Measurements were obtained while supine and while sitting at rest and during ankle exercise. Thigh-length GCS did not increase popliteal vein blood velocity, diameter, or volumetric blood flow while supine or sitting, with or without ankle exercise.

Background Previous studies reported graduated compression stockings can reduce the calibre of deep veins in the standing subjects. However, the literature has been inconclusive on the effect of graduated compression stockings on superficial veins in standing subjects. Objectives To assess the effect of two layers of graduated compression stockings on the diameter of saphenous veins in healthy subjects. Materials and methods In 17 legs of nine healthy subjects, we studied the effect of single layering and double layering of graduated compression stockings (23–32 mmHg, Thigh High Belted Sigvaris, Switzerland) on the diameter of the great saphenous vein mid-thigh, great saphenous vein mid-calf and small saphenous vein mid-calf. The measurements were taken using duplex ultrasound (Toshiba Aplio XG 500, 18-7 MHz transducer), through the fabric using a generous amount of ultrasound gel, on subjects both supine or prone and standing. Results Two layers of Class II graduated compression stockings reduced the calibre of great saphenous vein mid-thigh from (4.1 mm to 3.3 mm, p < 0.05), great saphenous vein mid-calf (2.8 mm to 2.2 mm, p < 0.01) and small saphenous vein (2.7 mm to 1.9 mm, p < 0.01) in the standing position. In the supine or prone position, great saphenous vein showed narrowing but there was no measurable change in the calibre of the small saphenous vein. The degree of narrowing was measurable, but insufficient to approximate the vein walls. Conclusion Superimposition of two Class II graduated compression stockings reduced the calibre of the saphenous veins in the standing position but did not approximate the vein walls. In the supine or prone position, the addition of a second layer of graduated compression stockings did not result in further narrowing of the saphenous veins.

Underlying Mechanisms

Oedema remains one of the most common causes of hand stiffness. Local venous return is intimately associated with oedema formation and management. To elucidate, the underlying mechanisms of venous return, the venous pumping systems in the hand were objectively and quantitatively investigated using Doppler ultrasound, cadaveric dissection and venography. It was demonstrated that functionally there are three independent venous systems: the superficial palmar, deep palmar and dorsal veins, which are activated by palm compression, isometric intrinsic muscle contraction, and dorsum compression, respectively. Each system was investigated independently and found to increase venous blood velocity in both the cephalic and ulnar veins. These systems were also shown to act in synergy, producing the greatest velocity increase when concurrently activated during fist-clenching. The volume of blood pumped during fist-clenching could also be potentiated by preloading by digit abduction. The clinical applications of these findings are discussed.

Background. The prone position is applied to facilitate surgery of the back and to improve oxygenation in the respirator-treated patient. In particular, with positive pressure ventilation the prone position reduces venous return to the heart and in turn cardiac output (CO) with consequences for cerebral blood flow. We tested in healthy subjects the hypothesis that rotating the head in the prone position reduces cerebral blood flow.Methods. Mean arterial blood pressure (MAP), stroke volume (SV), and CO were determined, together with the middle cerebral artery mean blood velocity (MCAVmean) and jugular vein diameters bilaterally in 22 healthy subjects in the prone position with the head centered, respectively, rotated sideways, with and without positive pressure breathing (10 cmH2O).Results. The prone position reduced SV (by5.4±1.5%;P<0.05) and CO (by2.3±1.9%), and slightly increased MAP (from78±3to80±2 mmHg) as well as bilateral jugular vein diameters, leaving MCAVmeanunchanged. Positive pressure breathing in the prone position increased MAP (by3.6±0.8 mmHg) but further reduced SV and CO (by9.3±1.3% and7.2±2.4% below baseline) while MCAVmeanwas maintained. The head-rotated prone position with positive pressure breathing augmented MAP further (87±2 mmHg) but not CO, narrowed both jugular vein diameters, and reduced MCAVmean(by8.6±3.2%).Conclusion. During positive pressure breathing the prone position with sideways rotated head reduces MCAVmean~10% in spite of an elevated MAP. Prone positioning with rotated head affects both CBF and cerebrovenous drainage indicating that optimal brain perfusion requires head centering.

SummaryAnkle exercise increases venous blood velocity while supine, but the effect of ankle exercise on venous blood velocity while sitting is not known. In this investigation, we test the hypothesis that venous blood velocity can be increased while sitting by repetitive dorsiflexion of the foot. Time-averaged peak velocity (TAPV) in the popliteal vein of 20 healthy male volunteers was measured by pulsed Doppler ultrasound at rest and during ankle exercise in the supine and sitting positions. Right popliteal vein TAPV while supine at rest was 11 cm/second (sec) (95% confidence interval [CI] =9–13 cm/sec) and with ankle exercise it increased to 24 cm/sec (95% CI =20–28 cm/sec) (p<0.0001). With sitting at rest, right popliteal vein blood TAPV decreased from 11 cm/sec to 3 cm/sec (95% CI = 2–4 cm/sec) (p<0.0001). With ankle exercise while sitting, right popliteal vein TAPV increased to 18 cm/sec (95% CI =15–21 cm/sec) (p<0.0001). In conclusion, in both the supine and sitting positions, ankle exercise increased venous blood velocity, thereby transiently reducing a tendency toward venous stasis. Such ankle exercise might be useful in the prevention of stasis-induced deep venous thrombosis.
