Dynamic changes of chest CT imaging in patients with corona virus disease-19 (COVID-19) / 浙江大学学报·医学版

OBJECTIVE@#To analyze the dynamic changes of chest CT images of patients with corona virus disease-19 (COVID-19).@*METHODS@#Fifty-two cases of COVID-19 were admitted in the First Affiliated Hospital of Zhejiang University School of Medicine. The consecutive chest CT scans were followed up for all patients with an average of 4 scans performed per patient during the hospitalization. The shortest interval between each scan was 2 days and the longest was 7 days. The shape, number and distribution of lung shadows, as well as the characteristics of the lesions on the CT images were reviewed.@*RESULTS@#The obvious shadows infiltrating the lungs were shown on CT images in 50 cases, for other 2 cases there was no abnormal changes in the lungs during the first CT examination. Ground-glass opacities (GGO) were found in 48 cases (92.3%), and 19 cases (36.5%) had patchy consolidation and sub-consolidation, which were accompanied with air bronchi sign in 17 cases (32.7%). Forty one cases (78.8%) showed a thickened leaflet interval, 4 cases (7.6%) had a small number of fibrous stripes. During hospitalization, GGO lesions in COVID-19 patients gradually became rare, the fibrous strip shadows increased and it became the most common imaging manifestation. The lesions rapidly progressed in 39 cases (75.0%) within 6-9 days after admission. On days 10-14 of admission, the lesions distinctly resolved in 40 cases (76.9%).@*CONCLUSIONS@#The chest CT images of patients with COVID-19 have certain characteristics with dynamic changes, which are of value for monitoring disease progress and clinical treatment.

CT imaging features of patients with different clinical types of coronavirus disease 2019 (COVID-19) / 浙江大学学报·医学版

OBJECTIVE@#To analyze the CT findings of patients with different clinical types of coronavirus disease 2019 (COVID-19).@*METHODS@#A total of 67 patients diagnosed as COVID-19 by nucleic acid testing were included and divided into 4 groups according to the clinical staging based on . The CT imaging characteristics were analyzed among patients with different clinical types.@*RESULTS@#Among 67 patients, 3 (4.5%) were mild cases, 35 (52.2%) were ordinary cases, 22 (32.8%) were severe cases, and 7 (10.4%) were critically ill. There were no abnormal CT findings in mild cases. In 35 ordinary cases, there were single lesions in 3 cases (8.6%) and multiple lesions in 33 cases (91.4%), while in severe case 1 case had single lesion (4.5%) and 21 had multiple lesions (95.5%). CT images of ordinary patients were mainly manifested as solid plaque shadow and halo sign (18/35, 51.4%); while fibrous strip shadow with ground glass shadow was more frequent in severe cases (7/22, 31.8%). Consolidation shadow as the main lesion was observed in 7 cases, and all of them were severe or critical ill patients.@*CONCLUSIONS@#CT images in patients with different clinical types of COVID-19 have characteristic manifestations, and solid shadow may predict severe and critical illness.

The CT imaging characteristics were analyzed among patients with different clinical types.@*RESULTS@#Among 67 patients, 3(4.5%) were mild, 35 (52.2%) were moderate, 22 (32.8%) were severe, and 7(10.4%) were critical ill. No significant abnormality in chest CT imaging in mild patients. The 35 cases of moderate type included 3 (8.6%) single lesions, the 22 cases of severe cases included 1 (4.5%) single lesion and the rest cases were with multiple lesions. CT images of moderate patients were mainly manifested by solid plaque shadow and halo sign (18/35, 51.4%); while fibrous strip shadow with ground glass shadow was more frequent in severe cases (7/22, 31.8%).

Pneumonectomy of right lung and carinal resection and reconstruction for lung cancer in 12 patients / 中国癌症杂志

Purpose:To discuss the treatments for lung cancer which involved carina of the bronchus and its complications. Methods:The surgical skill, airway management, postoperative complications of the pneumonectomy of right lung and reconstruction of carina and bronchus for lung cancer in 12 patients were discussed. Results:The 1.2.3 year survival rates are 100%(12/12),67%(8/12)and17%(2/12) respectively.There was no cases operative mortality and no severe past-operative complications. Conclusions:There is some value in this method but the indication must be strictly controlled.
