MSCT肺动脉造影在肺动脉栓塞的诊断应用研究(附22例分析)

摘要

目的 探讨多层螺旋CT肺血管造影(MSCTPA)诊断肺动脉栓塞(PE)的临床应用价值.方法 回顾性分析22例PE患者的MSCTPA图像.结果 22例PE患者中,累及肺动脉及其分支共285支,其中左、右PE 14支,叶PE 61支,段PE 152支,亚段PE 58支.PE的直接征象为肺动脉充盈缺损,包括中心型、锐角附壁型、钝角附壁型和完全闭塞型.结论 MSCTPA是快速、无创、安全检查PE的有效检查方法,对PE的诊断、指导治疗及判断疗效具有重要临床应用价值.%Objective To explore the clinical value of multi-slice spiral CT pulmonary angiography(MSCTPA) in the diagnosis of pulmonary embolism(PK).Methods The imaging of MSCTPA in 22 cases with pulmonary embolism were analyzed retrospectively.Results In 22 cases of PE patients,14 branch were diagnosed with around PE,61 branch were diagnosed with lobe PE,152 branch were diagnosed with segmental PE,and 58 branch were diagnosed with sub-segmental PE.Direct characteristic of PE was filling defects of pulmonary artery,central type,acute angle with wall type,obtuse angle with wall type and totally occluded type.Conclusion MSCTPA is a fast,non-invasive and safety method for examing pulmonary embolism effectively,it has important clinical application value for the diagnosis of pulmonary embolism,guide therapy and judgment of curative effect.
