升主动脉

Background— Bicuspid aortic valve is a heritable condition that has been linked by an unknown mechanism to a predisposition for ascending aortic aneurysm.

背景—二叶式主动脉瓣是一个易患升主动脉瘤的可遗传疾病，与升主动脉瘤连锁的机制还不清除。

In 15 anesthetized open-chest dogs, the responses of some regional vascular beds were examined by constant flow perfusion method during the 5-HT-induced aortic hypertensive chemoreflex.

在15只麻醉开胸犬中，用在体器官恒流灌注法研究了骨胳肌、皮肤、肾和心脏的血管在5-HT诱发的主动脉区化学感受性升血压反射中的反应，同时还观察了5-HT对这些器官血管的直接效应。

Objective To investigate the mechanical properties of ascending aorta in normal adult humans and different age pigs, and thus to provide essential biomechanical data for the vessels to be anastomosed in pig-to-human cardiac xenografts.

目的 ：探讨正常成人与不同月龄猪升主动脉一维载荷下的力学特性，为猪→人异种心脏移植吻合血管提供必要的生物力学基础。

ThomasⅡcardioplegic solution group:to establish CPB model via routine canulas, and ascending aorta was obstructed when temperature was reduced to 28-30℃,and the 4℃st.

ThomasⅡ停搏液组：常规插管转流，降温至28-30℃时阻断升主动脉，并于其根部注入4℃st。

Bentall's procedure can be effective in the treatment of ascending aortic aneurysm with aortic valve insufficiency. To improve surgical technique, reduce the CPB time, decreases the myocardial injury are the essential factors to the surgical success.

Bentall手术是治疗升主动脉瘤合并主动脉瓣关闭不全的有效办法，改善吻合技术、缩短体外循环及深低温停循环时间、保证移植后冠脉有效灌注是提高手术成功率的关键因素。
