支气管三维CT成像技术在小儿支气管扩张中的临床应用

摘要

目的:分析支气管三维CT成像技术在小儿支气管扩张中的临床应用.方法:随机选取2015年4月至2017年4月期间在芜湖市第二人民医院门诊就诊的40例支气管扩张小儿患者,均行64排螺旋CT三维成像扫描确诊,分别对囊状、柱状、静脉曲张型及混合型进行分析.结果:40例患者支气管的动脉主干部位均表现有明显的不同程度的扩张及弯曲、迂回,扩张部位累及肺部下方,支气管内供血动脉的分支间存在交叉沟通现象,诊断囊状型6例,柱状型10例,静脉曲张型15例,混合型9例.结论:64排螺旋CT三维成像技术对支气管扩张患者的诊断准确、清楚、全面,且操作简便、无创,值得在临床诊断中进一步推广及应用.%Objective To analyze the clinical value of three-dimensional CT imaging of the bronchus in the diagnosis of bronchiectasis in children.Methods Forty children with bronchiectasis visiting the Outpatient Department of Second People's Hospital of Wuhu between April,2015 and April,2017 underwent examinations by three-dimensional 64-slice spiral CT for a definite diagnosis.Different types of bronchiectasis were identified including cystic,columnar,varicose veins and mixed types.Results In all the cases,the bronchial arterial trunk showed obvious expansion,bending,and twisting.The expanded artery involved the lower lungs,and cross-communication was found among the artery branches supplying the bronchus.Bronchiectasis of the cystic type was diagnosed in 6 cases,columnar type in 10 cases,varicose veins in 15 cases,and mixed type in 9 cases.Conclusion Three-dimensional 64-slice spiral CT imaging can accurately diagnose bronchiectasis in children with minimal invasiveness.
