摘要
目的探讨老年无症状吸烟者的肺部高分辨CT(HRCT)表现并与非吸烟老年肺进行对比,以便提高吸烟对肺部损害的认识。方法对38例老年无症状吸烟者及63例非吸烟正常老年人的肺部HRCT表现进行配对分析。结果老年无症状吸烟者异常肺部HRCT表现明显高于非吸烟正常老年人(χ2=26.255,P<0.001),主要异常改变有:局限性或弥漫性肺气肿(18/38)、肺实质微结节(21/38)、空气潴留(11/38)、支气管壁增厚扩张(13/38)、小叶间隔增厚(8/38)及磨玻璃影(6/38)。结论吸烟对人体的损害是显而易见的,虽然没有临床症状,但吸烟对人体的潜在危害是不容忽视的,HRCT是早期显示X线及常规CT无法显示的肺损害的有效方法。
Objective To assess the HRCT findings of smoking-induced lung lesions in asymptomafic elderly subjects and compare with those in no-smoking elderly control subjects, so as to increase our knowledge of smoking-related lung damages. Methods Thirty-eight cases of asymptomatic smokers and 63 cases of no-smoking elderly volunteers were performed HRCT examination and their imagings were analyzed independently with at least 2 doctors. Results The rat of lung lesions of HRCT in asymptomatic elderly subjects was significantly higher than that in no-smoking elderly subjects (X^2= 26.255, P〈0.001). The lung lesions include: limiting or extensive emphysema (18/38), parenchymal micronodules (21/38), air trapping (11/38), bronchial wall thickening and / or brochiectasis (13/38), interlobular septal thickening (8/38) and ground- glass attenuation (6/38). Conclusion Cigarette smoking has several pathological effects on the lung, even though asymptomatic, the potential impairments should not be neglected. HRCT is considerably more sensitive than X-ray film and routine CT in the detection of early-stage smoking-related damage.
