The effect of limb elevation and the design of the thigh cuff outflow system on venous capacitance and venous outflow, as determined by strain gauge plethysmography, was reviewed in a group of normal limbs without evidence of deep venous thrombosis. We improved the reliability of plethysmography in evaluating venous outflow, particularly in the early period after cuff deflation, by using uniform leg elevation, large diameter outflow tubing, and single rather than simultaneous limb examinations. Based on this experience, an optimum technique of examination emphasizing precise limb elevation, sequential limb examination and proper design of the cuff outflow system was used to evaluate 21 patients with acute venous thrombosis. The results obtained were compared with previously reported results of strain gauge plethysmography in patients with acute venous thrombosis. This technique significantly reduced the incidence of false-positive results.
通过应变式容积描记法，对一组无深静脉血栓形成证据的正常肢体，研究了肢体抬高和大腿袖带流出系统设计对静脉容量和静脉流出的影响。我们通过采用统一的腿部抬高、大口径流出管道以及单肢而非同时检查双下肢，提高了容积描记法在评估静脉流出方面的可靠性，尤其是在袖带放气后的早期。基于这一经验，采用一种强调精确肢体抬高、逐肢检查以及袖带流出系统合理设计的最佳检查技术，对21例急性静脉血栓形成患者进行了评估。将所得结果与先前报道的急性静脉血栓形成患者的应变式容积描记法结果进行了比较。该技术显著降低了假阳性结果的发生率。
