We reviewed the records of 167 neonates and older children undergoing ligation of a patent ductus arteriosus to determine the prevalence of recurrent laryngeal nerve injury and identify risk factors that might increase the likelihood of injury. Paralysis or paresis of the left vocal cord was identified by fiberoptic laryngoscopy in seven patients. All seven weighted less than 1500 gm at the time of operation and the ductus had been ligated with a metal clip. All had persistent symptoms when observed for 5 to 19 months. Injury to the left recurrent laryngeal nerve occurs infrequently but may have long-term consequences.
我们回顾了167例接受动脉导管未闭结扎术的新生儿及大龄儿童的记录，以确定喉返神经损伤的发生率，并识别可能增加损伤可能性的危险因素。通过纤维喉镜检查发现7例患者左侧声带麻痹或轻瘫。所有7例患者在手术时体重均不足1500克，且动脉导管已用金属夹结扎。在观察5至19个月时，所有患者均有持续症状。左侧喉返神经损伤很少发生，但可能会产生长期后果。
