To evaluate capillary filtration a group of normal subjects and two groups of subjects with venous incompetence (50 with deep and 50 with superficial incompetence) were studied with the vacuum suction chamber (VSC) device applied onto the internal perimalleolar region. This method was compared with straingauge plethysmography rate of ankle swelling (RAS). By the VSC the time taken for the weal to disappear (VSC time) was considered indicative of capillary filtration. The values obtained with the two methods were well related (r < 0.742) and there was a good separation between patients and normals. The separation between the two groups of patients was significantly better (p < 0.05) with the VSC time. In conclusion VSC time is a good indication of capillary filtration in comparison with straingauge plethysmography RAS. It may be used to assess variations in capillary filtration in venous hypertension and possibly to follow up the effects of treatments.
为评估毛细血管滤过情况，对一组正常受试者以及两组静脉功能不全患者（50例深静脉功能不全患者和50例浅静脉功能不全患者）进行了研究，使用真空吸引室（VSC）装置作用于内踝区域。将该方法与应变片体积描记法测量的踝部肿胀率（RAS）进行比较。通过VSC，风团消失所需时间（VSC时间）被认为可指示毛细血管滤过情况。两种方法获得的值相关性良好（r < 0.742），患者与正常受试者之间有明显区分。两组患者之间的区分在VSC时间方面明显更好（p < 0.05）。总之，与应变片体积描记法RAS相比，VSC时间是毛细血管滤过的良好指标。它可用于评估静脉高压时毛细血管滤过的变化，并可能用于随访治疗效果。
