OBJECTIVES: Surgery of the aortic arch carries a risk of injury to the vagus and recurrent laryngeal nerves, particularly in a young child, as these structures lie in close proximity to aortic arch. This study aimed to determine the incidence, symptomatology and natural history of vocal cord dysfunction (VCD) following aortic arch reconstructive surgery through a median sternotomy approach.
METHODS AND MATERIALS: Prospective assessment was performed of all consecutive newborns who underwent cardiac surgery for aortic arch surgery via median sternotomy between January 2016 and May 2017 at a tertiary paediatric hospital. All patients underwent post-operative flexible fibreoptic nasolaryngoscopy (FNL) after extubation to assess for the presence of vocal cord dysfunction (VCD). Those with VCD were re-examined at followup. A feeding assessment performed by speech pathologists (SPs) and a video fluoroscopic swallow study (VFSS) were also performed in those with VCD or feeding difficulties.
RESULTS: A total of 35 newborns were included in the study. At initial review, left sided VCD was demonstrated in 65.7% of patients (n=23). Significant associations with VCD were younger age (3.0 versus 6.5 days, p=0.041) and a weak or absent cry (Relative Risk=16.4, 95%CI 3.8-47.8, p<0.001). 52.5% (n=11) of patients with VCD had evidence of aspiration on VFSS. There was no significant difference in intensive care unit stay or overall hospital stay between patients with VCD compared to those without (33.0 days vs 28.8 days, p=0.73; 52.5 vs 45.9, p=0.72.) Infants with either proven VCD or a weak cry were more likely to be discharged home with a nasogastric (NG) tube (RR=4.67, p= 0.048; RR=7.00 p=0.022 respectively). At followup after 106 days, complete resolution was seen in 100% patients with partial VCD and 61.5% with complete VCD.
CONCLUSIONS: VCD is a common complication following neonatal aortic arch surgery, although most experience resolution of symptoms over time. The authors recommend post-operative laryngoscopy in all patients should be routine, and particularly those with a weak cry.
