目的探讨应用64层螺旋CT肺动脉造影(CTPA)技术在诊断肺动脉栓塞中的临床价值。方法对商丘市第三人民医院2009年3月一2011年8月患者临床资料进行回顾性分析。结果本组31例患者经CTPA检查图像均显示良好,左右肺动脉、肺动脉主干及肺叶、段、亚段动脉的显示也令人满意。共累及亚段及亚段以上肺动脉252条,受累部位的直接征象为不同大小和不同程度的充盈缺损,间接征象则为肺梗死及胸腔积液等。受累的252条肺动脉中右肺动脉栓塞155条,左肺肺动脉栓塞97条。结论 CTPA对肺动脉栓塞的部位、范围及管腔狭窄程度显示良好,肺动脉阻塞指数可判断肺动脉栓塞的严重程度,为临床选择治疗方法及判定预后提供帮助。
Objective To investigate the clinical value of 64-slice spiral CT pulmonary angiography (CTPA) in the diagnosis of pulmonary embolism. Methods A retrospective analysis was performed on the clinical data of patients in Shangqiu Third People ’s Hospital from March 2009 to August 2011. Results The CTPA images of the 31 patients in this group showed good results. The left and right pulmonary arteries, the main pulmonary arteries and the lobes, segments and sub-arteries showed satisfactory results. A total of 252 sub-segments and sub-pulmonary artery involvement, the direct involvement of the affected parts of different sizes and different degrees of filling defects, indirect signs of pulmonary infarction and pleural effusion. Of the 252 pulmonary arteries involved, there were 155 right pulmonary embolism and 97 left pulmonary embolism. Conclusion The location and extent of pulmonary embolism and the extent of stenosis of CTPA are good. The severity of pulmonary embolism can be judged by the index of pulmonary artery occlusion, which can be helpful to choose the treatment method and prognosis.
