64排螺旋CT造影对肺栓塞表现和严重性判断的临床价值
[摘要] 目的 探讨64排螺旋CT造影对肺栓塞表现和严重性判断的临床价值。 方法 选择30例确诊的肺栓塞患者并与30例拟诊但后来经临床排除肺栓塞的患者比较，CT显示支气管动脉扩张和中央肺动脉受累情况，计算栓塞指数判断CT造影在肺动脉栓塞中的诊断价值。 结果 肺动脉栓塞组CT造影显示支气管动脉扩张和中央肺动脉受累的比例显著高于非肺动脉栓塞组，差异有统计学意义（P<0.05），而合并有基础心肺疾病的比例亦显著高于非肺动脉栓塞组，差异有统计学意义（P<0.05），肺动脉栓塞组的栓塞指数显著高于非肺动脉栓塞组，差异有统计学意义（P<0.05）。 结论 64排螺旋CT肺血管造影对于肺栓塞患者的检查，具有无创、快捷、可重复等特点，且其敏感性高，是一种初诊急性肺动脉栓塞的首选方法。

[Abstract] Objective To investigate the 64 row helical CT angiography diagnose for pulmonary embolism and judgment of severity of pulmonary embolism. Methods 30 cases with pulmonary embolism and 30 cases with suspected but after clinical to excluse of pulmonary embolism，used CT to judge bronchial artery dilatation and central pulmonary artery involvement and calculated embolism index of CT angiography for diagnosing of pulmonary embolism. Results The pulmonary embolism group with CT angiography showed that it"s bronchial artery dilatation and central pulmonary artery involvement were higher than non pulmonary embolism group （P<0.05），the basic cardiopulmonary disease combined ratio was higher than non pulmonary embolism group（P<0.05）， pulmonary embolism group plug index was significantly higher than non pulmonary embolism g...
