In an early series of 73 operations for patent ductus arteriosus, closure was by the triple ligation method. Over a short period, recurrence of patency was observed in 2 cases and after that the technique of division and suture rather than ligation became standard. For closure of the recurrent ductus, a modification of the usual technique is necessary to minimize danger of injury to the recurrent nerve and the great vessels. A safe method was devised which involves an intrapericardial approach to the superior aspect of the ductus and dissection inferiorly which avoids denudation of the aorta. This technique was used with satisfaction in 6 cases of recurrent patent ductus arteriosus.
在早期的73例动脉导管未闭手术中，采用三联结扎法进行闭合。在短时间内，观察到2例出现再通，此后，切断缝合而非结扎技术成为标准方法。对于复发性动脉导管的闭合，需要对常规技术进行改良，以尽量减少损伤喉返神经和大血管的风险。设计了一种安全方法，即采用心包内入路处理动脉导管的上缘，并向下解剖，避免主动脉裸露。该技术在6例复发性动脉导管未闭病例中使用效果良好。
