Anterior Aortopexy for Tracheomalacia

A modified surgical technique for aortopexy in tracheobronchomalacia

OBJECTIVES

Tracheobronchomalacia (TBM) is characterized by collapse of trachea, bronchi or both, leading to dyspnoea, expiratory stridor, coughing or recurrent airway infections. Surgical treatment with aortopexy is warranted for severe TBM. We describe a modified aortopexy technique with aortic wall strap sutures that evenly distributes the traction force over the full width of the aortic arch. The aim of this study was to determine the outcomes of this modified anterior aortopexy technique.

METHODS

Retrospective chart review of all patients undergoing aortopexy with aortic wall strap sutures for TBM between January 2010 and June 2020 in 2 tertiary hospitals in the Netherlands.

RESULTS

Twenty-four patients [median age 9 months (interquartile range 2-117 months); 71% male] underwent aortopexy with the modified technique for TBM (52%), tracheomalacia (40%) or bonchomalacia (8%). Aortopexy was successful in 91.7%, defined as relief or decrease of respiratory symptoms and no need for respiratory support. Complications occurred in 8.3% and mortality was 4%.

CONCLUSIONS

Aortopexy with non-absorbable strap sutures seems an effective and safe treatment for severe TBM. This study supports the hypothesis that strap sutures provide a solid and reliable traction force, but future comparative studies should confirm the benefit of strap sutures over conventional techniques.

Aortopexy for the treatment of tracheobronchomalacia in 100 children: a 10-year single-centre experience

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.
