摘　　要：目的探讨动态CT增强扫描在重症肝炎合并肺部感染诊断中的应用。方法回顾性分析我院2016年1月-2018年1月收治的120例重症肝炎患者的临床资料,依据是否肺部感染分为感染组(65例)与对照组(55例),比较两组患者的一般临床资料以及肺部CT表现,分析感染组肺部感染病原菌的构成情况,并比较不同病原菌所致肺部感染的CT表现特征。结果两组在磨玻璃影的CT表现差异无统计学意义(P>0.05);感染组的肺结实、肺结节、胸膜及胸腔病变的比例明显高于对照组(P<0.05);65例重症肝炎合并肺部感染患者中,共分离细菌7株,真菌58株,其中念珠菌占比最大,为53.85%;曲霉菌与念珠菌在CT表现结节个数、结节分型以及肺实变范围方面具有统计学意义(P<0.05),而在结节范围、胸膜及胸腔病变方面比较,差异无统计学意义(P>0.05)。结论重症肝炎合并肺部感染患者运用动态CT增强扫描诊断具有一定临床价值,其能早期检出病灶,并鉴别各种菌群感染。Objective To explore the application of dynamic CT enhanced scan in the diagnosis of severe hepatitis complicated with pulmonary infection.Methods The clinical data of 120 patients with severe hepatitis admitted to our hospital from January 2016 to January 2018 were retrospectively analyzed.According to whether the pulmonary infection occurred or not,the patients were divided into infection group (65 cases) and control group (55 cases).The general clinical data and pulmonary CT findings were compared between the two groups.And the compositions of pathogenic bacteria of pulmonary infection were analyzed in infection group,and the CT findings features of pulmonary infection caused by different pathogenic bacteria were compared.Results There was no significant difference in the ground-glass opacity between the two groups (P>0.05).The proportions of pulmonary consolidation,pulmonary nodules,pleural and thoracic lesions in infection group were significantly higher than those in control group (P<0.05).Among 65 patients with severe hepatitis and pulmonary infection,7 strains of bacteria and 58 strains of fungi were isolated,of which Candida accounted for the largest proportion,of 53.85%.There were significant differences in the nodules quantity,nodule classification and lung consolidation range between aspergillums and Candida from the aspect of CT findings (P<0.05),but there was no significant difference in the nodules range,pleural and thoracic lesions (P>0.05).Conclusion Dynamic CT enhanced scan for patients with severe hepatitis complicated with pulmonary infection has certain clinical value,and it can detect the lesions early and identify various bacterial infections.
