普通型COVID-19的胸部CT预后转归特征

Prognostic Characteristics of Chest CT in Common COVID-19

目的探讨普通型新型冠状病毒肺炎(COVID-19)的胸部CT预后转归特点。资料与方法纳入74例普通型COVID-19,首次CT呈典型肺部磨玻璃影(单发或≤3处多发灶为主),居家隔离治疗并复查CT,分析其预后特点及与发热的相关性。结果 44例(59.5%)呈好转趋势,复查间隔(9.0±3.5)d,发热消失,其中27例(61.4%)病灶完全吸收,10例(22.7%)大部分吸收;13例(17.6%)呈现游走趋势,复查间隔(8.0±2.8)d,发热反复;17例(22.9%)呈不良进展趋势,复查间隔(5.0±1.8)d,病灶范围增大或增多,且持续发热;CT预后转归与发热程度具有相关性(r=0.278,P=0.016)。结论 CT诊断为普通型COVID-19者,居家隔离治疗,发热持续缓解10 d以上可提示临床好转;1周内发热无缓解则提示进展。

Purpose To explore the prognostic characteristics of chest CT in common COVID-19.Materials and Methods Seventyfour patients with common COVID-19 were included.The first CT showed a typical ground glass shadow of lung(single or≤3 multiple foci).The patients were treated in isolation at home and followed up by chest CT to analyze their prognostic characteristics.Results 44 cases(59.5%)showed a trend of improvement.The reexamination interval was(9.0±3.5)days,and the sign of fever disappeared.Among them,27 cases(61.4%)completely absorbed the lesions,10 cases(22.7%)mostly absorbed;13 cases(17.6%)showed the trend of migration,the reexamination interval was(8.0±2.8)days,and the sign of fever repeated;17 cases(22.9%)showed a trend of poor progress,and the reexamination interval was(5.0±1.8)days,the range of lesions increased,and sign of fever continued;CT prognosis and the degree of fever were statistically correlated(r=0.278,P=0.016).Conclusion For common COVID-19 diagnosed by chest CT and treated with isolation treatment at home,continuous remission of fever for more than 10 days may indicate clinical improvement;if there is no remission within one week,it should indicate the progress and need to be hospitalized.
