Abstract：
UNASSIGNED: The aim of this study was to compare pressure resistance of the most common methods of vessel occlusion during thoracic surgical procedures: ligations, clips, and vascular endostaplers.
UNASSIGNED: Pulmonary vessels were obtained during routine thoracic surgeries. A ball-tipped cannula was inserted through an opening in the side wall and secured with a linen ligature from slipping out. Subsequently, saline was infused into the vessel. We recorded the pressure on which a leakage occurred.
UNASSIGNED: A total of 65 vessels, divided between 3 groups, were enrolled in the study. In the endostaplers group, median bursting pressures were 262.5 mmHg and 300 mmHg for arteries and veins, respectively. In the case of clips, it was over 750 mmHg in both types of the vessels. The same results were observed in the ligation group. Minimal bursting pressures in endostapler occlusion were 187.5 mmHg and 225 mmHg in arteries and veins, respectively. In the case of clips, it was 600 mmHg for arteries and 675 mmHg for veins. A total of 525 mmHg (arteries) and 750 mmHg (veins) were the minimal leaking values observed in vessels occluded with ligations. Comparative analysis showed statistically significant differences in endostapler-clips and endostapler-ligations pairs (p < 0.001). There were no differences between clips and ligations.
UNASSIGNED: The examined methods are capable of occluding pulmonary vessels under physiological conditions. Furthermore, ligations and clips are resistant to pressures highly exceeding physiological values.

摘要：
■这项研究的目的是比较胸外科手术中最常见的血管闭塞方法的耐压性：结扎，夹子,和血管内缝合器。
■在常规胸外科手术中获得肺血管。将球形套管插入侧壁中的开口，并用亚麻结扎线固定以免滑出。随后，盐水注入血管。我们记录了发生泄漏的压力。
■总共65艘船，分成三组，参加了这项研究。在内窥镜组中，动脉和静脉的中位爆裂压为262.5mmHg和300mmHg，分别。在夹子的情况下，这两种类型的血管都超过750mmHg。在连接组中观察到相同的结果。内缝合器闭塞的最小破裂压力为动脉和静脉的187.5mmHg和225mmHg，分别。在夹子的情况下，动脉为600mmHg，静脉为675mmHg。总共525mmHg（动脉）和750mmHg（静脉）是在结扎阻塞的血管中观察到的最小泄漏值。比较分析显示，内缝合器-夹子和内缝合器-结扎对的差异具有统计学意义（p<0.001）。剪辑和结扎之间没有区别。
■所检查的方法能够在生理条件下阻塞肺血管。此外，结扎和夹子对高度超过生理值的压力具有抵抗力。
