Left recurrent laryngeal nerve palsy secondary to left pulmonary artery stent in a child.

We report a 10-year-old girl who developed persistent hoarseness after stent placement for the treatment of left pulmonary artery stenosis. Laryngoscopy performed 21 months after stent placement revealed left vocal cord paralysis, presumed secondary to compression of the left recurrent laryngeal nerve by the stent. Pediatric cardiologists should be reminded of this possible rare complication after stent placement.
