目的：采取彩色多普勒超声对慢性阻塞性肺疾病急性加重期的患者进行检查，判断其对于患者出现下肢静脉血栓的诊断价值。方法从我院确诊为慢性阻塞性肺疾病的患者中随机抽出100例分为对照组和试验组各50例，试验组患者采取彩色多普勒超声对患者的下肢深静脉血栓情况进行检查，对照组患者采取D-二聚体检测，比较两组患者检查的灵敏度及特异度、准确率情况。结果试验组患者检查的灵敏度为62.00%，对照组患者为72.00%，比较不具有统计学意义（P>0.05），而在检查的特异度方面，试验组患者为94.00%，明显高于对照组的34.00%，在统计学上有意义（P<0.05），试验组患者检查的准确度为84.00%，对照组患者仅为44.00%，P<0.05，差异具有统计学意义。结论彩色多普勒超声检查在慢性阻塞性肺疾病患者的急性加重期，可以特异的检测出患者下肢静脉血栓的情况，并且具有很高的准确性，具有诊断意义，可以作为首选检查应用于临床。%Objective To check patients with acute exacerbation of chronic obstructive pulmonary disease and determine its diagnostic value for patients with venous thrombosis. Methods 100 patients diagnosed as chronic obstructive pulmonary disease in our hospital were randomly divided into control group and test group, each group with 50 cases. Patients with deep venous thrombosis in experimental group were taken on color Doppler ultrasound, patients of control group were taken on Ddimer testing. The sensitivity, accuracy and specific degrees were observed. Results Sensitivity of experimental group was 62.00%, in the control group was 72.00%, there was no statistically significance (P>0.05). Specific degree of inspection in treatment group patients was 94.00%, significantly higher than the control group 34.00%, there was statistically significant (P<0.05). In terms of specificity inspection, the test group of patients was 94.00%,significantly higher than control group (34.00%), the difference was statistically significant. Conclusion Color doppler ultrasound in the acute aggravating period of patients with chronic obstructive pulmonary disease, can be specific to detect patients with venous thrombosis of the lower extremities, and has high accuracy and diagnostic significance, can be used as a preferred examination of clinical applications.
