The radio- and angiocardiographic characteristics of 19 infants with an interrupted aortic arch were reviewed. There were three with type A (distal to the left subclavian artery), 15 with type B (between the left carotid and subclavian arteries), and one with type C (between the innominate and left carotid arteries). Associated cardiovascular anomalies were numerous, a ventricular septal defect (19/19) and a patent ductus arterisous (18/19) being the most common. Plain film signs of aortic interruption were nonspecific. Left ventriculography using angled oblique views was diagnostic of the interruption and most other abnormalities. The constant presence of a ventricular septal defect and frequent occurrence of left ventricular outflow obstruction in these infants lends support to the theory that decreased flow in the fetal ascending aorta predisposes to interruption of the aortic arch.
回顾了19例主动脉弓中断婴儿的放射学和心血管造影特征。其中3例为A型（左锁骨下动脉远端），15例为B型（左颈动脉和锁骨下动脉之间），1例为C型（无名动脉和左颈动脉之间）。相关的心血管异常众多，室间隔缺损（19/19）和动脉导管未闭（18/19）最为常见。主动脉中断的平片征象不具特异性。采用斜位投照的左心室造影可诊断主动脉中断及大多数其他异常。这些婴儿中室间隔缺损的持续存在以及左心室流出道梗阻的频繁发生支持了以下理论：胎儿升主动脉血流减少易导致主动脉弓中断。
