摘　　要：目的探讨原发性水痘肺炎(PVP)的危险因素及CT表现,为PVP早期诊断提供临床依据。方法回顾性选取99例水痘患者,分为肺炎组(53例)和对照组(46例),分析性别、年龄、住院前发热天数、最高体温、呼吸系统症状、白细胞(WBC)计数、淋巴细胞绝对值(ALC)等因素与PVP的相关性。采用多因素logistic分析确定PVP的危险因素,并总结PVP患者的CT特征表现。结果肺炎组和对照组在年龄、呼吸系统症状、ALC差异有统计学意义(P<0.05);年龄、呼吸系统症状是PVP的独立危险因素(P<0.05);CT主要特征为双肺散在小实性结节伴晕征,可以合并磨玻璃影或小实变影,同时可见腋窝淋巴结增大。结论年龄、呼吸系统症状可作为预测水痘患者并发PVP的独立危险因素,结合患者CT特征表现,对PVP早期诊断具有重要价值。Objective To investigate the risk factors and CT manifestations of primary varicella pneumonia(PVP),and to provide clinical evidence for early diagnosis of PVP.Methods A total of 99 patients with varicella were retrospectively selected,and all patients were divided into pneumonia group(53 cases)and control group(46 cases).The correlations between factors such as gender,age,febrile days before hospitalization,maximum body temperature,respiratory symptoms,white blood cell(WBC)count,absolute lymphocyte count(ALC)and PVP were analyzed.Multivariate logistic analysis was used to determine the risk factors of PVP,and the CT features of PVP patients were summarized.Results There were significant differences in age,respiratory symptoms and ALC between pneumonia group and control group(P<0.05).Age and respiratory symptoms were independent risk factors for PVP(P<0.05).The main features of CT were scattered small solid nodules in both lungs with halo sign,which could be combined with ground glass shadow or small solid shadow,and axillary lymph node enlargement.Conclusion Age and respiratory symptoms can be used as independent risk factors for predicting PVP in varicella patients,and combined with CT features of patients,it is of great value for the early diagnosis of PVP.
