螺旋CT在肺动脉栓塞中的临床应用

Clinical application of spiral CT in pulmonary artery embolism

目的探讨螺旋CT诊断在肺动脉栓塞中的临床应用价值。方法回顾我院2011年1月～2012年5月通过螺旋CT检查的肺动脉栓塞患者52例资料并进行分析。结果通过检查发现,双肺患病22例(42.31%),右肺20例(38.46%),左肺10例(19.23%),对比发现,右肺发病率明显增高,与其他肺部栓塞发生率比较,差异具有统计学意义(P<0.05)。共累及肺动脉436支。本组检查同时发现合并肺梗死12例,合并胸腔积液10例,合并肺炎4例,合并心包积液7例。不同轴面图像及MPR在左、右主肺动脉及肺叶动脉检查结果一致。肺段及肺亚段动脉存在差异,而层厚1 mm明显优于层厚3 mm,肺段动脉不同层厚及MPR对比差异无统计学意义(P>0.05);肺亚段动脉不同层厚对比差异有统计学意义(P<0.05);层厚1mm与MPR对比差异无统计学意义(P>0.05)。结论运用螺旋CT检查肺动脉栓塞准确率高、患者易接受。

Objective To explore the diagnosis of spiral CT in pulmonary artery embolism in clinical application. Methods From January 2011-May 2012 by spiral CT examination in 52 eases of acute pulmonary embolism with multislice spiral CT examination and analysis. Results The found by inspection, double lung prevalence of 22 （42.31%） eases, right lung in 20 （38.46%） cases, left in 10 （19.23%） eases, contrast, right pulmonary morbidity was increased, and the other lung em- bolism occurred rate comparison, the difference was significant, P 〈 0.05. A total of 436 pulmonary arteries involvement. The inspection also found associated with pulmonary infarction in 12 cases, 10 cases with pleural effusion, pneumonia in 4 eases,7 cases with pericardial effusion. Different axial images and MPR in the left, the right main pulmonary artery and pulmonary artery examination results. Segmental and subsegmental arterial pulmonary existence difference, and thickness of lmm was better than the thickness 3 mm, pulmonary artery of different thickness and MPR comparison （P 〉 0.05）; pul- monary segmental artery of different layer thickness contrast （P 〈 0.05）; thickness lmm in comparison with MPR （P 〉 0.05）. Conclusion Pulmonary embolism using spiral CT has high accuracy of examination, do not harm the patient etc.
