重型SARS患者的转归及胸部影像学随访观察研究

目的 探讨重型SARS患者的转归并随访观察其恢复期胸部影像学表现。方法 回顾性分析54例重型SARS患者的转归，随访观察25例重型SARS患者恢复期的胸片、CT扫描表现。结果 54例重型SARS患者，死亡15例(其中1例尸检)，临床治愈39例。随访观察的25例中21例随访时间为发病后158—238d，CT扫描发现8例有肺间质增生(38．10％)；4例有纤维性病灶(19．05％)；12例有磨玻璃样密度病变残留(57．14％)；7例双肺未见异常改变(33．33％)。结论 肺间质增生、纤维性病灶、磨玻璃样密度病变残留是重型SARS患者恢复期的主要胸部表现，其发生率高于普通型SARS患者。

The outcome and follow-up research on the chest imaging appearances in critical SARS patients

Objective To investigate the outcome of critical SARS patients and to follow up the occurrence of the complications on chest films in convalescent cases.Methods The outcome of 54 cases with critical SARS was retrospectively analyzed, and the chest films and CT images were tracking researched in convalescent critical SARS patients.Results Among the 54 patients with critical SARS, 15 cases died (autopsy was done in 1 case) and 39 cases were cured. 21 cases were followed up from 158 to 238 days after onset. CT findings revealed pulmonary interstitial hyperplasia in 8 cases (38.1%), fiber shadows in 4 cases (19.05%), ground-glass shadows in 12 cases (57.14%), and normal in 7 cases (33.33%), respectively.Conclusion Pulmonary interstitial hyperplasia, fiber shadow, and ground-glass shadow are the main complications in the lung in convalescent critical SARS patients. The occurrence rate is higher than common SARS.
