One plethysmographic and two thermographic methods were evaluated against venography in 102 patients with suspected deep vein thrombosis (DVT). Seventy-one patients had venographically verified DVT, which in 21 cases was restricted to the calf. Plethysmography (PG) gave a sensitivity and specificity of 63% and 94%, respectively. The former was influenced by a limited sensitivity of 14% in the sub-group with distal DVT. The sensitivity and specificity of temperature profiles (TP) were 87% and 39%, respectively, while the corresponding values for thermo-camera (TC) were 83% and 55%, respectively. Using a combined diagnostic approach of PG and TP, additional evaluation of posterior and lateral profiles and pattern recognition, 96% sensitivity and 81% specificity were reached. The combination of PG and TP will be an essential diagnostic complement when venography is not possible or inconclusive, as well as having a role in diagnostic screening in a large number of patients.
对102例疑似深静脉血栓形成(DVT)的患者,将一种体积描记法和两种热成像方法与静脉造影术进行了对比评估。71例患者经静脉造影证实患有DVT,其中21例局限于小腿。体积描记法(PG)的敏感性和特异性分别为63%和94%。在远端DVT亚组中,前者受限于14%的低敏感性。温度曲线(TP)的敏感性和特异性分别为87%和39%,而热像仪(TC)的相应值分别为83%和55%。采用PG和TP的联合诊断方法,对后侧和外侧曲线进行额外评估并结合模式识别,敏感性达到96%,特异性达到81%。当无法进行静脉造影或结果不确定时,PG和TP的联合将是一种重要的诊断补充手段,并且在大量患者的诊断筛查中也能发挥作用。
