摘要

背景:严重COVID-19肺炎的罕见但令人不安的后果是肺组织进行性降解,表现为大疱性肺气肿改变或肺消失综合征(VLS)。目的:探讨重症COVID-19肺炎患者肺综合征消失的CT特征。方法:对新冠肺炎急性期重症肺炎患者67例,发病后3 ~ 6个月内因呼吸衰竭需要反复住院的病例进行回顾性分析。所有患者均行CT扫描。分析VLS患者的CT扫描结果。结果。年龄31 ~ 68(52.6±3.3)岁的67例患者中有16例(12例(75%)男性)出现VLS。CT特征见表1。表1。结论:重症COVID-19肺炎后不仅出现GGO、ILST、纤维化样改变和肺实变,而且出现VLS。VLS主要表现为多发、单发大疱,罕见的为直径大于30mm的大疱性肺气肿,占一半。VLC的危险并发症是气胸。

Computed tomography (CT) characteristics of vanishing lung syndrome in patients after severe COVID-19 pneumonia
Background: The rare but disturbing consequence of the severe COVID-19 pneumonia is progressive degradation of lung tissue as bullous-emphysematous changes or vanishing lung syndrome (VLS). Aim: to investigate the CT characteristics of vanishing lung syndrome in patients (pts) after severe COVID-19 pneumonia. Methods. 67 pts who suffered severe pneumonia during the acute period of COVID-19 and need repeated hospital admission due to respiratory failure in the term 3–6 month after disease start were examined. All pts underwent CT scan. CT scans of pts with VLS were analyzed. Results. VLS was revealed in 16 (12 (75%) men) from 67 pts aged 31 to 68 (52.6±3.3) years. The CT characteristics are shown in Table 1. Table 1. VLS CT scan changes and their frequency (n, %) Conclusion: After severe COVID-19 pneumonia not only GGO, ILST, fibrosis-like changes and lung consolidation, but the VLS occurs. Mainly VLS appears as the multiple bullas, solitary bullas and rare as bullous emphysema with diameter more 30 mm in a half of cases. The threatening complication of VLC is pneumothorax.
