摘　　要：目的　长期随访SARS后遗症-肺纤维化的变化,观察预后。方法　分别于SARS患者发病后6、9、12个月,采用螺旋CT行胸部扫描随访检查SARS康复人员肺纤维化变化。结果　6个月:5 6例患者中2 2例胸部CT显示局部磨玻璃和(或)网格状影,肺纤维化发生率39.2 9%。9个月:6 3例患者中2 2例胸部CT显示局部磨玻璃样或(和)网格状影,肺纤维化发生率34.92 %。12个月:74例患者中2 8例胸部CT显示局部磨玻璃样或(和)网格状影,肺纤维化发生率37.84 %。3组间比较无显著性差异( χ2 =0 .6 88,P >0 0 5 )。比较不同时间CT检查所见的侵及肺叶数目,随时间延长逐渐减少,3组之间差异显著( χ2 =5 .898,P <0 0 5 )。结论　1年随访结果表明SARS后遗症-肺纤维化病情稳定。Objective To follow up the changes in pulmonary fibrosis,a sequela of SARS.Methods Pulmonary fibrosis in 56,63 and 74 patients was followed up by spiral CT 6,9,and 12 months,respectively,after onset of SARS.The scans were analyzed by three experts .Results At 6 months after onset,the frosted-glass-like and (or) grid-form shadow was seen in 22 of 56 SARS patients (39.29%).At 9 months,frosted-glass-like and (or) grid -form shadow was shown in 22 of 63 SARS patients (34.92%).And at 12 months,the frosted-glass-like and (or) grid-form shadow remained in 28 of 74 SARS patients (37.84%);There was no significant difference between the three groups(χ 2= 0.688 ,P>0.05).But the number of the affected lung lobes decreased with time with a significant difference between the three groups(χ 2= 5.898 ,P<0.05).Conclusion The pulmonary fibrosis in the SARS patients is stable and tends to be alleviated with increasing time.
