目的总结血栓试验联合16层螺旋CT检查在急性肺血栓栓塞症早期诊断中的应用价值。方法将2008年3月—2010年3月收治的疑似肺血栓患者60例,及选取的20例健康人员分为两组,每组40例,疑似患者与健康者均为3∶1,进行检查准确性的验证。对照组采用血栓试验进行检查,观察组采用血栓试验结合CT检查,对两组患者的准确率、诊断敏感性、特异性、阳性预测值、阴性预测值、诊断指数及可用度等数据进行比较。结果对照组的准确率为67.5%,观察组准确率为90.0%,两组差异有统计学意义(χ2=6.050,P=0.014)。CT肺动脉造影可以清楚显示血栓部位、形态、与管壁的关系及内腔受损状。结论血栓试验联合螺旋CT检查在急性肺血栓栓塞症早期的诊断中具有重要价值。
Objective To summarize the value of thrombosis combined with 16-slice spiral CT in the early diagnosis of acute pulmonary thromboembolism. Methods Sixty patients with suspected pulmonary thromboembolism who were admitted from March 2008 to March 2010 were selected and divided into two groups, 40 cases in each group and 3: 1 in suspected patients and healthy subjects Verification of accuracy. The control group was tested by thrombus test. Thrombus test and CT examination were used in the observation group to compare the accuracy, diagnostic sensitivity, specificity, positive predictive value, negative predictive value, diagnostic index and availability of the two groups. Results The accuracy rate of the control group was 67.5%, and the observation group was 90.0%. The difference between the two groups was statistically significant (χ2 = 6.050, P = 0.014). CT pulmonary angiography can clearly show the location of thrombus, morphology, and the relationship between the wall and the lumen impaired. Conclusion Thrombus test combined with spiral CT examination is of great value in the early diagnosis of acute pulmonary thromboembolism.
