起源于主支气管、叶支气管的肺癌称为中央型肺癌。
Originated in the main bronchi, the bronchial lung cancer known as central lung cancer.
病变支气管范围长，多为主支气管、叶支气管、段支气管连续或间断受累；
The main bronchi, lobar bronchi and segmental bronchi were usually invaded continuously or intermittently, with a longer extension;
CT均显示叶支气管腔内结节状或栓子状影像 ，以及不同程度的阻塞征象。
The nodules or emboluses within lobaris bronchus were showed by CT in all cases and the obstructive signs on each patient in its degrees.
前言： 目的：探讨支气管肺癌侵犯叶支气管以上及隆凸的手术适应证和并发症。
Purpose:To discuss the treatments for lung cancer which involved carina of the bronchus and its complications.
结果发现2 3例患者粘稠痰液阻塞一侧主支气管或叶支气管，为阻塞性肺不张；
Results Unilateral bronchus or lobar bronchus was obstructed by thick sputum in 23 patients, where the atelectasis was obstructive.
目的总结叶支气管腔内癌的CT征象及其临床特点，提高对本病的认识和诊断水平。
Objective to summarize the ct signs and clinic characteristics to improve the ct diagnoses ability on the lobar bronchial intraluminal cancer and provide a well comprehension for it.
结果：MRI显示叶支气管闭塞准确率16／20例，显示叶支气管狭窄准确率4／4例。
Result:MRI accuracy rate was 16/20 in cases showing lobar bronchial obstruction, 4/4 for cases showing stenosis.
大叶性肺气肿可由于局部小支气管梗阻所引起。
Lobar emphysema may result from partial bronchial obstruction.
结果典型结节并具有深分叶征，毛刺征，小泡征，含气支气管征，胸膜凹陷征，血管集束征对恶性结节的诊断具有较高价值。
Results Typical nodules with deep lobulated sign, spiculated sign, vacuole sign, air bronchogram, pleural indentation, and vessel convergence has great value in the diagnosis of malignant SPN.
接着空气通过喉下至气管，气管分为两根，称为主支气管，每一根主支气管通入一叶肺。
The air then passes through the larynx and down the trachea. The trachea splits into two tubes, called the primary bronchi. One bronchus passes into each lung.
