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 5 4例重型SARS患者的转归 ,随访观察 2 5例重型SARS患者恢复期的胸片、CT扫描表现。结果 5 4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 2 5例中 2 1例随访时间为发病后 15 8～ 2 38d ,CT扫描发现 8例有肺间质增生 (38 10 % ) ;4例有纤维性病灶 (19 0 5 % ) ;12例有磨玻璃样密度病变残留 (5 7 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。
Objective To investigate the outcomes of patients with severe acute respiratory syndrome (SARS) and to observe their chest radiographic performance at follow-up. Methods The clinical data of 54 severe SARS patients were retrospectively analyzed. The chest X-ray and CT scan findings of 25 patients with severe SARS at follow-up were observed. Results Fifty-four patients with severe SARS died in 15 cases (one of them was autopsied) and 39 cases were clinically cured. Among the 25 follow-up cases, 21 cases were followed up for 15 8 to 2 38 days after the onset of disease. Eight cases had pulmonary interstitial hyperplasia (38 10%) on CT scan, 4 cases had fibrous lesion (19 0 5%), Twelve cases had residual glass-like density lesions (57.14%); no abnormal changes were observed in 7 cases (33.33%). Conclusions Pulmonary interstitial fibrosis, fibrous lesion and ground-glass density lesion are the main chest manifestations in convalescence of severe SARS patients, and their incidence is higher than that of common SARS patients.
