Abstract：
Truncus arteriosus (TA, also known as common arterial trunk) consists of only one great artery (\"the truncus\") with a semilunar valve (truncus valve) arising from the heart and an additional ventricular septal defect and (Fig. 50.1). This great artery is positioned above the ventricular septal defect and gives rise to the coronary arteries, the pulmonary arteries, and the aortic arch. Historically, TA has been classified by Collet and Edwards in three types, where in type I there was a common pulmonary artery truncus, in type II the left and right PA arise separately but close to each other, in type III both PA arise independently; in addition, there was a type IV that was later characterized as pulmonary atresia with VSD and major aortopulmonary collateral arteries arising from the descending aorta.
摘要：
动脉干（TA，也称为普通动脉干）仅由一条大动脉（“干”）和一个由心脏引起的半月瓣（干瓣膜）和一个额外的室间隔缺损组成（图。50.1).这条大动脉位于室间隔缺损上方，并产生冠状动脉，肺动脉,和主动脉弓.历史上,科莱和爱德华兹将TA分为三种类型，在I型中有一个常见的肺动脉干，在II型中，左PA和右PA分别出现，但彼此靠近，在III型中，两个PA都独立出现；此外，有一种IV型,后来表现为肺动脉闭锁伴VSD,主要主肺侧支动脉起因于降主动脉.
