The effect of incremental increases in external pressure, applied to the leg, on blood volume flow in the femoral vein was studied in dogs. Clinical investigation of external pressure increases was also carried out on nine patients undergoing surgery for varicose veins. An external pressure between 5 and 15 mm. Hg caused a sustained increase in mean femoral vein flow both in a control and in the compressed limb. Above 15 mm. Hg external pressure flow decreased in the compressed limb but was maintained at an increased level in the control limb.If external compression is to be used to prevent and treat deep vein thrombosis its application must be carefully controlled.
在狗身上研究了逐渐增加施加于腿部的外部压力对股静脉血容量流动的影响。还对9名接受静脉曲张手术的患者进行了外部压力增加的临床研究。5至15毫米汞柱的外部压力使对照肢体和受压肢体的股静脉平均血流持续增加。外部压力超过15毫米汞柱时，受压肢体的血流减少，但对照肢体的血流维持在增加水平。如果要用外部压迫来预防和治疗深静脉血栓形成，其应用必须得到仔细控制。
