纤支镜选择性支气管造影对肺部疾病的诊断意义

Significance of Fibero-bronchoscopic Selective bronchography in the Diagnosis of Lung Disorders

对39例肺疾病患者应用纤支镜选择性支气管造影检查。结果显示肺癌组病变处支气管呈不规形扁平,刀鞘与鼠尾状狭窄,造影缺损、阻塞、管壁僵硬如枯技状;肺泡癌有肺泡充盈不良、缺损和造影剂不能进入肺泡。肺炎组病变支气管均充盈显影。肺结核组支气管呈变形扭曲、扩张和狭窄。支气管扩张、肺良性肿瘤、肺结节病、病灶处支气管均清晰显影。部分病例有压迫支气管推移变形。对肺部周围性病变未确诊者进行选择性造影可提高诊断率。

Fibero—bronchoscopic selective bronchography was performed in 39 patients with various lung disorders. The results revealed that in lung cancer the lesions showed irregular flattening, sword—sheath shaped or rat—tail shaped stricture, filling defects, obstruction and rigidity of the bronchial wall; in alveolar carcinona the lesions were characterized by filling defects or failure into bronchio alveolar duct; in pulmonary tuberculosis the bronchi demonstrated various dysmorphosis such as twisting, narrowing and or dilating, in bronchiectasis, benign tumor of the lungs and pulmonary sarcoidosis the bronchi around the lesions were well filled, and distortion of the bronchi was found in certain patients. The selective broncho graphy may be of diagnostic value in patients with peripheral lesions of the lungs.
