After-exercise thermography of the legs was carried out on 50 patients before undergoing major abdominal surgery (group 1) and on 59 patients before elective hip surgery (group 2). The incidence of postoperative deep vein thrombosis (DVT)--diagnosed by the 125I-fibrinogen uptake test in group 1 and phlebography in group 2--was significantly higher in patients whose after-exercise thermogram (AET) had been abnormal. Out of 19 patients in group 1 and 30 in group 2 with a normal AET, two and nine repsectively developed postoperative DVT. Among patients with a unilaterally abnormal AET the incidences were 12 out of 19 patients in group 1 and five out of nine in group 2. The incidences among patients with a bilaterally abnormal AET rose to 11 out of 12 patients in group 1 and 15 out of 20 in group 2. Preoperative after-exercise thermography is a simple, objective test that identifies patients at high risk of developing postoperative thromboembolic disease.
对50例接受腹部大手术前的患者（第1组）和59例择期髋关节手术前的患者（第2组）进行了腿部运动后热成像检查。术后深静脉血栓形成（DVT）的发生率——第1组通过¹²⁵I-纤维蛋白原摄取试验诊断，第2组通过静脉造影诊断——在运动后热成像图（AET）异常的患者中显著更高。在第1组19例和第2组30例AET正常的患者中，分别有2例和9例发生术后DVT。在单侧AET异常的患者中，第1组19例中有12例，第2组9例中有5例。双侧AET异常的患者中，第1组12例中有11例，第2组20例中有15例。术前运动后热成像检查是一种简单、客观的检查方法，可识别术后发生血栓栓塞性疾病风险较高的患者。
