Measurement of lower limb volume in patients with chronic venous disease (CVD) is necessary for assessing severity at the time of diagnosis and evaluating response to therapy administered. Existing methods have some limitations in clinical application and accuracy. The study aimed to investigate the reliability and validity of a three-dimensional laser scanner (3DLS) in measuring the lower limb volume of patients with CVD.
A total of 30 patients with CVD (mean age, 55.6 ± 8.07 years; mean body mass index, 24.61 ± 1.87) were recruited in a vascular surgery clinic. The lower limb volumes of all participants were measured using the 3DLS and circumferential method (CM). Statistical analysis was conducted to compare the 3DLS and CM.
There was a strong correlation between the CM and 3DLS method (r = 0.9065). The 3DLS had a high intraoperator and interoperator reliability. A Bland-Altman plot showed satisfactory agreement between the two methods. The 3DLS demonstrated greater bilateral limb differences than CM.
There was satisfactory agreement between the two investigated methods. The 3DLS method was confirmed to be accurate, repeatable, and rapid in measuring the lower limb volume in patients with CVD and is, therefore, suitable for clinical use.
测量慢性静脉疾病（CVD）患者的下肢容积对于诊断时评估疾病严重程度以及评估所给予治疗的反应是必要的。现有方法在临床应用和准确性方面存在一些局限性。本研究旨在探讨三维激光扫描仪（3DLS）测量CVD患者下肢容积的可靠性和有效性。
在一家血管外科诊所招募了30例CVD患者（平均年龄55.6±8.07岁；平均体重指数24.61±1.87）。使用3DLS和周径法（CM）测量所有参与者的下肢容积。进行统计分析以比较3DLS和CM。
CM与3DLS方法之间存在强相关性（r = 0.9065）。3DLS具有较高的操作者内和操作者间可靠性。Bland-Altman图显示两种方法之间具有令人满意的一致性。3DLS显示出比CM更大的双侧肢体差异。
两种研究方法之间具有令人满意的一致性。3DLS方法被证实测量CVD患者下肢容积准确、可重复且快速，因此适用于临床应用。
