Patent ductus arteriosus (PDA) is a common problem in preterm newborns. Left vocal cord paralysis (LVCP) can complicate surgical closure if the recurrent nerve is damaged.
A retrospective case series study was conducted on preterm babies diagnosed with PDA in our unit from 1999 to 2013. Their clinical features and treatment complications were reviewed. In those patients that received surgical treatment a telephone questionnaire on the symptoms of LVCP symptoms was completed, and laryncoscopy examination offered.
A total of 88 subjects diagnosed with PDA were found, of whom 13.64% (12/88) needed surgery. These patients had a lower gestational age and birth weight. They required mechanical ventilation more frequently, and they had more complications such as, diaphragmatic paralysis, bronchopulmonary dysplasia and intraventricular hemorrhage. One third (3/9) of the surgically treated patients had LVCP, and all of them had dysphonia (100% vs. 16.7%, p=.05).
LVCP is a common complication of PDA surgery. Further studies are needed to determine its risk factors and its short and long-term consequences.
动脉导管未闭（PDA）是早产新生儿的常见问题。如果喉返神经受损，左侧声带麻痹（LVCP）会使手术闭合变得复杂。
对1999年至2013年在我院诊断为PDA的早产婴儿进行回顾性病例系列研究。回顾了他们的临床特征和治疗并发症。在接受手术治疗的患者中，完成了关于LVCP症状的电话问卷调查，并进行了喉镜检查。
共发现88例诊断为PDA的受试者，其中13.64%（12/88）需要手术。这些患者的胎龄和出生体重较低。他们更频繁地需要机械通气，并且有更多并发症，如膈神经麻痹、支气管肺发育不良和脑室内出血。三分之一（3/9）接受手术治疗的患者患有LVCP，并且他们都有发音障碍（100%对16.7%，p = 0.05）。
LVCP是PDA手术的常见并发症。需要进一步研究以确定其危险因素及其短期和长期后果。
