In two hypoxia groups VEGF expression in vascular smooth muscle cells of pulmonary artery trunk and pulmonary arteriole increased significantly while no difference was found in smooth muscle cells of aorta .

缺氧组大鼠肺动脉 主干及 肺内小动脉平滑肌细胞内VEGF的表达明显增强并随着缺氧时间的延长而增加；

Methods : The main trunk of the pulmonary artery was dissected in the male Sprague-Dawley rat and cut into arterial ring in 3 ~ 4 mm width .

方法：从雄性 Sprague-Dauley大鼠中分离出 肺主动脉，切成3～4mm的血管环。

Invasion of pulmonary artery trunk by pulmonary carcinoma : review of 19 cases

肺癌侵犯肺动脉 干19例

On the section through bifurcation of pulmonary trunk apicoposterior and anterior segmental arteries arised from left pulmonary artery . The apicoposterior and anterior segmental bronchi lay on the lateral side of left pulmonary artery .

在肺动脉 杈层面上，左 肺动脉发出尖后段动脉和前段动脉，其外侧可见尖后段支气管和前段支气管。

Results Both the ventricular septum and its defect were best demonstrated on transverse scans while overriding aorta was best seen on coronal scans and pulmonary trunk and right pulmonary artery on sagittal scans .

结果30例室间隔及其缺损均在横断面扫描显示最佳，25例 主动脉骑跨在冠状面扫描显示清晰，5例显示不清。

Conclusions : pulmonary artery can be adopted sleeve and lateral wall resections when lung neoplasms invades the trunk or the root of its branches of pulmonary artery .

结论：（1）如肿瘤侵犯 肺动脉 主干及其分支根部，动脉切除后可采用袖式吻合及侧壁扩大成形术；

The interlobar trunk of right pulmonary artery and the summit of the righthilar angle were observed and measured on30 adult cadavers .

在30例成尸标本上对右肺门角顶点的位置和右 肺动脉叶间 干进行了观测。

Twenty-four hours after thrombolytic therapy 1 of 8 cases presented enlarging embolism area in left pulmonary artery trunk and fresh thrombosis was found in the posterior basal branch of the left pulmonary artery in another case .

溶栓治疗后24h行CT血管造影（CTA）复查的8例患者中1例左肺动脉 干栓塞加重，1例左下 肺后基底段新出现栓塞；

47.5 % of pulmonary artery trunk main pulmonary artery and interlobar artery 63.3 % of lobar artery and 59.7 % of segmental artery had PE .

47.5%肺叶以上动脉（主 肺动脉、左右肺动脉 主干及双侧中间段动脉）、63.3%肺叶动脉及59.7%肺段动脉受累。

Results 97 pulmonary arteries ( 51 % ) were involved including 40 % pulmonary artery trunk main pulmonary and 61 % interlobular arteries and segment arteries .

结果12例病例，分析190支 肺段以上 肺动脉，共累及97支肺动脉（51%），其中40%的肺动脉 主干和叶以上 肺动脉受累，61%的叶 肺动脉和段 肺动脉受累。

The donor brachiocephalic trunk ( innominate ) and pulmonary artery were anastomosed to the recipient right common carotid artery and right external jugular vein respectively .

将供心的无名 动脉 和 肺动脉分别与受体的右颈总动脉和右颈外静脉行套管法连接。
