探讨多排螺旋CT肺动脉造影检查在肺动脉栓塞诊断中的应用价值

Clinical Value of Multislice Spiral CT Pulmonary Angiography on the Diagnosis of Pulmonary Embolism

目的探讨多排螺旋CT肺动脉造影(MSCTPA)检查技术对肺动脉栓塞(PE)诊断的应用价值。方法选择本院2013年9月~2016年5月临床诊断为PE并行MSCTPA的72例患者,通过影像表现分析该检查对PE诊断的价值。结果 72例患者共发现肺动脉栓子346个,其中中央型肺动脉栓子106个,周围型肺动脉栓子240个。多排螺旋CT肺动脉造影表现直接征象为中心型栓塞(129支)、偏心型栓塞(151支)、附壁环形栓塞(24支)、完全闭塞型栓塞(43支),间接征象常有肺动脉高压(30例)、肺梗死(20例)、心影增大(14例)、胸腔积液(32例)、心包积液(10例)。结论多排螺旋CT肺动脉造影检查具有无创、快速的优点,可作为诊断高原地区肺动脉栓塞的首选影像学检查手段。

Objective： To investigate the clinical value of multislice spiral CT pulmonary angiography on the diagnosis of pulmonary embolism.Methods： Totally, 72 Tibetan patients with pulmonary embolism were examined by multislice spiral CT pulmonary angiography from September 2013 to May 2016 as the objects of study. Through imaging presentation, the clinical value of multislice spiral CT pulmonary angiography on the diagnosis of pulmonary embolism was reviewed and analyzed.Results： A total of 346 pieces of emboli were found in 72 ca ses, among which 106 pieces of central emboli, 240 pieces of peripheral emboli were found. The multislice spiral CT direct signs of pulmonary angiography were central type （ 19 counts）, septal type （151 counts ）, mural type （43 counts）, and total-occlusion type （43 counts）. In addition, the indirect signs were pulmonary hypertension （30 cases）, pulmonary infarction （20 cases）, cardiac enlargement （14 cases）, pleural effusion （32 cases）, and pericardial effusion （10 cases）. Conclusions： The examination of multislice spiral CT pulmonary angiography is featured with non- invasive, and rapid, etc., which is a preferred imaging examination in detection of pulmonary embolism.
