A gravimetric plethysmograph, the technique of its use and its evaluation in vascular surgical practice are described. The instrument measures flow by the increase in leg weight (rather than volume) produced by an increase in blood content resulting from venous occlusion. The instrument was found to be convenient to use and satisfactory records were obtained in 88% of patients. Values for flow at rest and during reactive hyperaemia were clearly related to the presence of indications for surgical treatment and were similar to those reported by other workers. It is suggested that a peak hyperaemic flow of greater than 15 g 100 ml-1 min-1 may indicate that there are no indications for surgical treatment. The changes in hyperaemic flow values after treatment were clearly related to the symptomatic improvement resulting from it. It is concluded that the gravimetric plethysmograph is suitable for use in the assessment of patients with obliterative arterial disease of the legs.
本文描述了一种重量体积描记器及其在血管外科实践中的使用技术和评估。该仪器通过测量静脉阻塞导致血液含量增加而引起的腿部重量增加（而非体积增加）来测定血流量。结果发现该仪器使用方便，88%的患者获得了满意的记录。静息和反应性充血时的血流值与手术治疗指征的存在明显相关，且与其他研究人员报告的结果相似。有人提出，充血峰值血流大于15 g 100 ml-1 min-1可能表明无手术治疗指征。治疗后充血血流值的变化与由此导致的症状改善明显相关。结论是，重量体积描记器适用于评估腿部闭塞性动脉疾病患者。
