Traction bronchiectasis

中文百科

支气管扩张 Bronchiectasis

(重定向自Traction bronchiectasis)

支气管扩张英语:Bronchiectasis)指的是肺脏中支气管永久性的扩张。患者的常见症状包括有痰的慢性咳嗽,其他还有呼吸困难、咳血与胸痛等,有些患者同时也有喘鸣与杵状指的情形。患者也常罹患肺部(下呼吸道)感染

支气管扩张症可能源自于一些后天因素或是感染(包括肺炎、结核、免疫系统问题、以及囊肿纤维症等)。几乎所有囊肿纤维症的患者最后都会患上这种病症,而未患囊肿纤维症的支气管扩张症患者中,有10%到50%的病因不明。支气管扩张症的机转是呼吸道组织因不受控制的发炎反应而崩解,受疾病影响的支气管管径扩张,清除分泌物的能力也因此受损。支气管中的分泌物使肺中的细菌量增加、造成气道阻塞和进一步的破坏。在分类上,支气管扩张症与气喘和慢性阻塞性肺病同属于阻塞性肺病。当求诊者的症状符合此疾病的病症时,可由电脑断层检查确诊。至少每年进行一次痰液细菌培养,对诊断快速恶化的患者也可能有效。
