This study was conducted to identify specific abnormalities using the results from air plethysmography in legs with lymphedema. A routine air plethysmography exercise protocol was performed in 31 patients with unilateral leg lymphedema, and the results were compared with those of 53 patients with unilateral great saphenous vein reflux and 15 normal subjects. The venous filling index in legs with lymphedema (2.1 ± 1.2 mL/sec) was smaller than in legs with great saphenous vein reflux (6.4 ± 4.1 mL/sec, p < 0.05), but was not different from that in normal legs (1.9 ± 1.2 mL/sec). The ejection fraction was similar in all groups. The residual volume fraction in legs with lymphedema (35 ± 32%) was larger than that in normal subjects (13 ± 23%, p < 0.05), but was not significantly different from that in the contralateral leg of the lymphedema patients (32 ± 27%). In conclusion, we found no specific air plethysmography findings in uncomplicated lymphedema.
本研究旨在通过空气体积描记法在下肢淋巴水肿患者的结果中识别出特定的异常。对 31 例单侧下肢淋巴水肿患者进行了常规空气体积描记法运动方案，并将结果与 53 例单侧大隐静脉反流患者和 15 例正常受试者进行了比较。淋巴水肿腿的静脉充盈指数（2.1 ± 1.2 mL/sec）小于大隐静脉反流腿（6.4 ± 4.1 mL/sec，p < 0.05），但与正常腿无差异（1.9 ± 1.2 mL/sec）。各组的射血分数相似。淋巴水肿腿的残留容积分数（35 ± 32%）大于正常受试者（13 ± 23%，p < 0.05），但与淋巴水肿患者的对侧腿无显著差异（32 ± 27%）。总之，我们在单纯性淋巴水肿中未发现特定的空气体积描记法发现。
