Abstract：
Lower extremity edema is a symptom of chronic venous disease and venous insufficiency. However, clinical evaluations rely on the qualitative evaluation of the pitting depth, which is neither well-defined nor quantitative. We created a novel three-dimensionally printed edema ruler as a quantitative method to measure pitting depth. Twenty-five patients (50 legs) with chronic venous disease were evaluated for ankle edema using the edema ruler. The results demonstrate excellent intraclass correlation for both single (0.944, P < .001) and average (0.971, P < .001) measurements. The edema ruler is a noninvasive, useful, and objective tool for the clinical measurement of lower extremity edema.
摘要：
下肢水肿是慢性静脉疾病和静脉功能不全的症状。然而,临床评价依赖于点蚀深度的定性评价，既不明确也不定量。我们创建了一种新颖的三维打印水肿尺，作为测量点蚀深度的定量方法。使用水肿尺评估了25例慢性静脉疾病患者（50条腿）的踝关节水肿。结果证明了单个(0.944,P<.001)和平均(0.971,P<.001)测量的优异的组内相关性。水肿标尺是一种非侵入性的，有用的,和客观工具，用于下肢水肿的临床测量。
