目的探讨螺旋CT肺血管造影联合D-二聚体在肺栓塞(PE)诊断中的价值。方法对85例疑似PE患者进行检查。分别评价螺旋CT肺血管造影、D-二聚体及两者联合检测对PE的诊断价值。结果螺旋CT肺血管造影诊断PE的灵敏度、特异性分别为87.8%、95.2%,血浆D-二聚体诊断PE的灵敏度、特异性分别为95.4%、63.7%,两者联合检测的灵敏度、特异性分别提高到88.9%和85.7%。结论螺旋CT肺血管造影联合D-二聚体可明显提高诊断PE的灵敏度和特异性。
Objective To investigate the value of spiral CT pulmonary angiography combined with D-dimer in the diagnosis of pulmonary embolism (PE). Methods 85 cases of suspected PE patients were examined. The diagnostic value of spiral CT pulmonary angiography, D-dimer and their combination in the diagnosis of PE were evaluated. Results The sensitivity and specificity of spiral CT pulmonary angiography in diagnosing PE were 87.8% and 95.2%, respectively. The sensitivity and specificity of plasma D-dimer in diagnosing PE were 95.4% and 63.7% respectively. The sensitivity and specificity of combined detection Sex increased to 88.9% and 85.7% respectively. Conclusion Spiral CT pulmonary angiography combined with D-dimer can significantly improve the sensitivity and specificity of PE.
