OBJECTIVE: To determine the frequency of recurrent laryngeal nerve injury after surgery for patent
METHODOLOGY: This Descriptive study was conducted in the Cardiovascular Department, of a tertiary
care hospital in Khyber Pakhtunkhwa over a period of six months.
Infants with patent ductus arteriosus and failed medical treatment were selected from outpatient setting
and admitted in surgical ward of the hospital for further workup. After written informed consent, all the
infants were put on next OT list for surgical closure of PDA which were performed by single experience
cardiothoracic surgeon using standard left posterolateral thoracotomy approach. At the time of exudation
anesthetist looked for any Vocal cord paralysis.
Post operatively all infants were kept in ward for the next one day and symptoms on the basis of mother
of the child complaining of stridor (on history and physical examination),coughing and choking while
feeding and hoarseness of voice were assessed 24 hrs after the surgery.
RESULTS: The frequencies and percentages for of recurrent laryngeal nerve injury were 12 (11.42%)
after PDA surgery.
CONCLUSIONS: This study documented recurrent laryngeal nerve injury after patent ductus arteriosus
ligations. The percentage suggests that a higher proficiency in patent ductus arteriosus ligations needs to
be ensured in pediatric surgery training programs.
