A previous history of deep venous thrombosis (DVT) must be carefully evaluated in every patient affected by chronic venous insufficiency (CVI); the assessment of deep venous system patency is the goal of preoperative diagnosis. Air plethysmography examination allows an outpatient noninvasive testing of calf pump function and deep venous outflow. The authors report the results of a study on 37 patients (40 limbs) with a previous history of DVT, suffering from CVI; in 18 limbs air plethysmography showed a marked increase of calf volume on test exercise, suggesting residual venous obstruction. The authors believe that air plethysmography examination is mandatory before operation in patients with a previous history of DVT.
对于每一位患有慢性静脉功能不全（CVI）的患者，都必须仔细评估其既往深静脉血栓形成（DVT）病史；评估深静脉系统通畅情况是术前诊断的目标。空气体积描记法检查可对小腿泵功能和深静脉流出情况进行门诊无创检测。作者报告了一项针对37例（40条肢体）有DVT病史且患有CVI患者的研究结果；在18条肢体中，空气体积描记法显示测试运动时小腿体积显著增加，提示存在残余静脉阻塞。作者认为，有DVT病史的患者在手术前必须进行空气体积描记法检查。
