A new technique is reported for constriction of the pulmonary artery ostium as a palliative procedure in infants with type I truncus arteriosus. Pulmonary artery plication was performed without cardiopulmonary bypass, and this allowed intraoperative evaluation of the procedure. The lungs were protected from developing pulmonary vascular obstructive disease, and congestive heart failure resolved. The pulmonary arteries and the ostium grew with the child so that corrective surgery could be delayed until 4 1/2 years of age, when a large (20 mm) valved extracardiac conduit could be placed. We believe this is a useful palliative operation, particularly for small, sick infants, and it deserves further evaluation.
据报道，一种用于缩窄肺动脉口的新技术可作为I型永存动脉干婴儿的姑息性手术。在没有体外循环的情况下进行肺动脉折叠术，这使得术中能够对手术进行评估。肺部可预防发生肺血管阻塞性疾病，充血性心力衰竭也得到缓解。肺动脉及其开口会随着患儿生长，因此矫正手术可推迟至4岁半，届时可植入一个大型（20毫米）带瓣心外管道。我们认为这是一种有用的姑息性手术，尤其适用于病情较重的小婴儿，值得进一步评估。
