CT检查应用于肺源性心脏病肺动脉高压的临床价值

The Clinical Value of CT Examination Applied to Cor Pulmonale Pulmonary Hypertension

目的:研究CT胸部平扫加增强扫描检查应用于肺源性心脏病肺动脉高压的临床价值。方法:选择2012年11月-2013年11月本院诊断为肺源性心脏病住院患者40例作为研究对象,其中放射线检查组20例采用放射线胸部检查,CT检查组20例采用CT胸部平扫加增强扫描检查,两组患者均在治疗前后进行检查。比较两组患者治疗前后主肺动脉,左、右肺动脉直径变化。结果:肺总动脉、左右肺动脉的直径比较:放射线检查组治疗前后各径线有显著性差异(P<0.01),但右下肺动脉干直径≥15 mm为12例(60%),说明胸片测量右下肺动脉干直径对与诊断肺心病肺动脉高压虽有一定的临床价值,但其特异性较差。CT检查组平扫加增强扫描检查结果各径线比较有显著性差异(P<0.01);右下肺动脉干直径全部≥15 mm,显著高于放射线检查组(P<0.01),特异性强。结论:CT检查应用于肺源性心脏病肺动脉高压的诊断及治疗效果评价具有临床价值。

Objective： To study the clinical value of the CT plain scan and enhanced scan is applied to cor pulmonale pulmonary hypertension.Method ： 40 patients with cor pulmonale in the hospital from November 2012 to November 2013 were selected as the research object, one of the group of 20 patients with radiation chest check the radio- graphic inspection group, another group of 20 cases by chest CT scan and enhanced scan CT inspection group, two groups of patients were checked before and after therapy, before and after treatment the main pulmonary artery, left and right pulmonary artery diameter changes of the two groups were compared.Result： The diameter of the pulmonary artery, leg and fight pulmonary artery： diagnosis by radiation t results compared before and after the treatment lines had significant difference （ P〈0.01 ）, but lower right pulmonary artery of stem diameter of 15 mm were 12 cases （ 60% ）, show the X-ray measurement fight pulmonary artery stem diameter for diagnosis of lung pulmonary hypertension was of certain clinical value, but its specificity was poor. CT plain scan and enhanced scan results all lines had significant difference （ P〈0.01 ）, in the lower fight pulmonary artery all stem diameter 15 mm or higher, significantly higher than that of radio- graphic inspection group （P〈0.01）, and strong specificity.Conclusion： CT examination is applied to the diagnosis of pulmonary hypertension and cor pulmonale therapeutic effect evaluation of clinical value.
