Abstract：
The literature reports that there was a significant difference in the medical impact of the coronavirus disease (COVID-19) pandemic between European and East Asian countries; specifically, the mortality rate of COVID-19 in Europe was significantly higher than that in East Asia. Considering such a difference, our narrative review aimed to compare the prevalence and characteristics of residual lung abnormalities at one-year follow-up computed tomography (CT) after severe or critical COVID-19 in survivors of European and East Asian countries. A literature search was performed to identify articles focusing on the prevalence and characteristics of CT lung abnormalities in survivors of severe or critical COVID-19. Database analysis identified 16 research articles, 9 from Europe and 7 from East Asia (all from China). Our analysis found a higher prevalence of CT lung abnormalities in European than in Chinese studies (82% vs. 52%). While the most prevalent lung abnormalities in Chinese studies were ground-glass opacities (35%), the most prevalent lung abnormalities in European studies were linear (59%) and reticular opacities (55%), followed by bronchiectasis (46%). Although our findings required confirmation, the higher prevalence and severity of lung abnormalities in European than in Chinese survivors of COVID-19 may reflect a greater architectural distortion due to a more severe lung damage.
摘要：
文献报道，欧洲和东亚国家之间冠状病毒病（COVID-19）大流行的医疗影响存在显着差异；具体而言，欧洲的COVID-19死亡率明显高于东亚。考虑到这种差异，我们的叙述性综述旨在比较欧洲和东亚国家幸存者中严重或危重COVID-19后1年随访计算机断层扫描(CT)残留肺部异常的患病率和特征.进行了文献检索，以确定有关严重或危重COVID-19幸存者CT肺部异常的患病率和特征的文章。数据库分析确定了16篇研究文章，9来自欧洲，7来自东亚（全部来自中国）。我们的分析发现，欧洲的CT肺部异常患病率高于中国的研究（82％vs.52%)。虽然在中国研究中最普遍的肺部异常是毛玻璃混浊（35％），欧洲研究中最普遍的肺部异常是线性（59％）和网状混浊（55％），其次是支气管扩张(46%)。虽然我们的发现需要确认,与中国的COVID-19幸存者相比，欧洲人的肺部异常患病率和严重程度更高，这可能反映了由于更严重的肺损伤而导致的更大的结构扭曲。
