囊性纤维化 (CF) 中的气道改造是多样化的,支气管切除症的严重程度不能预测肺功能. 小型气道疾病在晚期CF中至关重要,无论有明显的气道变化.
科学领域:
- 肺部医学 肺部医学
- 放射学 放射学是一门学科.
- 病理学 病理学 病理学
背景情况:
- 囊性纤维化 (CF) 已知会导致支气管切除和阻塞性功能障碍.
- 小气道改造在CF中的作用,特别是它与支气管切除症的联系,尚不清楚.
研究的目的:
- 通过详细的成像和组织学,在晚期CF中对大小呼吸道疾病进行形态测量分析.
- 调查气道改造和CF中的功能障碍之间的关系.
主要方法:
- 使用ex-vivo高分辨率计算机断层扫描 (HRCT) 和微计算机断层扫描 (μCT) 对已扩展的CF和对照肺部.
- 进行了气道体积,气道细分,远距离气道直径和气道崩的形态分析.
- 补充成像与组织学分析的远端气道崩.
主要成果:
- 在HRCT上,气道体积百分比 (AV%) 显示了CF和对照肺之间的重叠,表明异质支气管切除.
- 微型CT显示CF肺部 (9-16代) 均的小气道损失.
- AV%与肺功能 (FEV1) 或开放的远距离气道无关;然而,开放的远距离气道与肺功能相关. 倒塌的远距离气道在组织学上显示扩张和收缩性支气管炎.
结论:
- 末期CF的气道改造是异质的,有不同程度的支气管切除和小气道扩张.
- 支气管切除症的严重程度与功能障碍或小气道损失的程度无关.
- 小型气道疾病在晚期的CF中起着重要作用,独立于可见的支气管病变.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
