OBJECTIVES Our study describes and analyses the results from aortopexy for the treatment of airway malacia in children. METHODS Demographic data, characteristics and preoperative, operative and outcome details, including the need for reintervention, were collected for children undergoing aortopexy between 2006 and 2016. RESULTS One hundred patients [median age 8.2 months, interquartile range (IQR) 3.3–26.0 months] underwent aortopexy. Sixty-four (64%) patients had tracheomalacia (TM) only, 24 (24%) patients had TM extending into their bronchus (tracheobronchomalacia) and 11 (11%) patients had bronchomalacia. Forty-one (41%) children had gastro-oesophageal reflux disease, of which 17 (41%) children underwent a Nissen fundoplication. Twenty-eight (28%) children underwent a tracheo-oesophageal fistula repair prior to aortopexy (median 5.7 months, IQR 2.9–17.6 months). The median duration of follow-up was 5.3 years (IQR 2.9–7.5 years). Thirty-five (35%) patients were on mechanical ventilatory support before aortopexy. Twenty-seven (77%) patients could be safely weaned from ventilator support during the same admission after aortopexy (median 2 days, IQR 0–3 days). Fourteen patients required reintervention. Overall mortality was 16%. Multivariable analysis revealed preoperative ventilation (P  = 0.004) and bronchial involvement (P  = 0.004) to be adverse predictors of survival. Only bronchial involvement was a predictor for reintervention (P  = 0.012). CONCLUSIONS Aortopexy appears to be an effective procedure in the treatment of children with severe airway malacia. Bronchial involvement is associated with adverse outcome, and other procedures could be more suitable. For the treatment of severe airway malacia with isolated airway compression, we currently recommend aortopexy to be considered. [ABSTRACT FROM AUTHOR]

To gather detailed data on the incidence of phrenic nerve damage (PND) following cardiac surgery in children, the risk factors for its development, its effect on morbidity and its prognosis. Prospective electrophysiological measurement of phrenic nerve latency in 310 children before and after cardiac surgery. Tertiary paediatric cardiac surgical centre. Our findings were fourfold. Firstly, the incidence of PND in our group of patients was 20%, significantly higher than estimates using indirect methods of assessment. Secondly, PND increased the duration of ventilation by a median of 76 h (20 vs. 96 h; p < 0.001), and late post-operative deaths (before hospital discharge) occurred in 12.9% of patients compared to 2.4% among patients with a normal post-operative phrenic latency. Thirdly, the risk factors that were independently predictive of the development of PND were the site of the surgery and the patient's age. Patients who required surgery at both the lung hilum and the pericardium were more likely to develop PND than patients with only one of those sites, or when neither was involved, and children less than 18 months old were more likely to develop PND than older children. Lastly, the natural history of PND following surgery appears to be good. In our follow-up to 3 months, approximately one third recovered within 1 month and a further third (overall) recovered by 3 months. We conclude that the incidence of PND is much higher than currently recognised, and has a very significant effect on post-operative morbidity and mortality. Most children who survive the post-operative period will recover nerve function within 3 months. [ABSTRACT FROM AUTHOR]

Introduction Slide tracheoplasty is now considered gold standard treatment for long segment congenital tracheal stenosis. Outcomes are typically focused upon airway patency. Dysphagia is often reported in children undergoing cardiothoracic surgery, but not specifically after slide tracheoplasty. This study was carried out to describe the nature and prevalence of dysphagia following slide tracheoplasty for long segment congenital tracheal stenosis. Methods Retrospective case note review was conducted on a series of patients who underwent swallow evaluation following slide tracheoplasty between 2006 and 2014. A clinical swallow assessment was carried out by a Speech and Language Therapist with videofluoroscopic evaluation of swallowing where indicated. Logistic regression assessed the impact of gender, feeding history, weight, tracheal diameter, stenting and co-morbidities on the likelihood of having post-operative dysphagia. Results 43 out of 83 slide tracheoplasty patients underwent swallow evaluation. Dysphagia was identified in 30 (70%) of 43 patients. Videofluoroscopy was undertaken in 22 of these patients. All patients who had a videofluoroscopy presented with altered swallow physiology. Aspiration risk was confirmed in 15 patients with frank aspiration seen in 9. Pre-operative history of dysphagia was present in 9 patients. There were two cases of vocal fold palsy. The presence of a stent was the strongest predictor of post-operative dysphagia with an odds ratio of 10.6 (95% CI 1.2–92.8). Conclusions This study documents a high prevalence of post-operative dysphagia in a pediatric population following slide tracheoplasty. In most cases there was no history suggestive of dysphagia pre-operatively. Swallowing needs to be assessed after slide tracheoplasty and longitudinal studies are required. [ABSTRACT FROM AUTHOR]
