1·Invasion of main bronchus.

侵犯主支气管。

2·Objective To review the experience in surgical treatment for tumors of trachea, carina and main bronchus.

目的总结气管、隆凸主支气管肿瘤手术治疗经验，探讨合理的手术方法及治疗措施。

3·The tumor seen here has caused obstruction of the main bronchus to left lung so that the distal lung is collapsed.

图示肿瘤导致左主支气管阻塞，因此远端肺组织塌陷。

4·Results Multi-slice helical CT show all 14 foreign bodies, included 8 in trachea, 4 in left main bronchus, 2 in right main bronchus.

结果14例患者中，多层螺旋ct均直接显示气道异物。其中：气管异物8例，左主支气管异物4例，右主支气管2例。

5·Conclusions: The animal study shows that it is feasible to repair tracheal defects with main bronchus by a 2-stage autotransplantation procedure.

结论：本动物实验表明，采用分期自体左主支气管移植、修复气管缺损是可行的。

6·This is a squamous cell carcinoma of the lung that is arising centrally in the lung (as most squamous cell carcinomas do). It is obstructing the right main bronchus.

发生于肺中央（与绝大多数鳞状细胞癌一样）的鳞状细胞癌，刚好阻挡右主支气管。

7·Objective To design the trachea main bronchus covered embranchment stent and study the primary treatment for thoracostomach main bronchial fistula and main bronchial stenosis.

目的设计治疗胸腔胃主支气管瘘和主支气管狭窄的气管主支气管覆膜分支状内支架。

8·IN THE hierarchy of transplant surgery,replacing a bronchus (the passage from the main windpipe, the trachea, into alung) does not sound difficult compared with, say, plumbing in a new heart.

在移植级别的手术室中，替换一个支气管（主气管的分支，通入到肺中）听起来与在一个新的心脏中搭桥相比，一点也不困难。

9·Conclusion Medical history and imaging manifestation were the main approaches to diagnose nonmetal foreign body in trachea and bronchus.

结论病史及影像学表现是诊断气管、支气管非金属异物的主要手段。
