Four neonates presented within 24 hours of birth with stridor, respiratory distress and a weak cry. Clinical examination of the cardiovascular system revealed no abnormality. The transthoracic echocardiogram showed large aneurysm of ductus arteriosus at the aortic isthmus, tapering to a small tortuous channel at the site of pulmonary artery insertion. Computerized tomography scan performed in two of the neonates demonstrated considerable compression of adjacent thoracic structures. One required surgical excision due to persistence of symptoms. Serial echocardiograms in the remaining three babies showed transition through various stages of resolution over a period of 6 weeks to 3 months, resulting in the obliteration of the aneurysm. All babies are doing well during the follow-up.
四名新生儿在出生后24小时内出现喘鸣、呼吸窘迫和哭声微弱的症状。心血管系统的临床检查未发现异常。经胸超声心动图显示主动脉峡部动脉导管巨大动脉瘤，在肺动脉插入处逐渐变细为一个小的迂曲通道。对其中两名新生儿进行的计算机断层扫描显示相邻胸部结构受到相当程度的压迫。一名因症状持续存在而需要手术切除。其余三名婴儿的系列超声心动图显示，在6周至3个月的时间内经历了不同阶段的消退过程，最终动脉瘤消失。所有婴儿在随访期间情况良好。
