Aortopexy for tracheomalacia via a suprasternal incision

Aim

Tracheomalacia is flaccidity of the tracheal wall leading to tracheal collapse, particularly on expiration. When severe it can warrant surgical intervention. Aortopexy is one surgical option and has been described using a variety of approaches. We report outcomes of aortopexy performed via a suprasternal incision in a single centre by a single surgeon.

Methods

All patients undergoing aortopexy between February 2016 and May 2018 were prospectively included. Patients were managed by a multi-disciplinary team (MDT) and underwent standardized work-up, including dynamic flexible bronchoscopy (DFB) and contrast enhanced CT. Aortopexy was performed via a suprasternal skin crease incision. Surgery was guided by intra-operative flexible bronchoscopy. Data regarding pre-operative symptoms, degree of tracheomalacia, and outcomes were recorded.

Results

Twenty-two patients were included, 18 boys, median age 5?months (range 1?month–5?years). Two aortopexy sutures were used in all cases, and three patients required an additional tracheopexy suture. Median operating time was 1?h 24?min (range 47?min–2?h 35?min). Median pre-operative tracheal collapse on DFB was 85% (range 80–95%), improving to 35% (35–80%) intra-operatively. Median length of stay was 4?days (range 1–118).

Conclusions

Aortopexy via a suprasternal incision is a useful treatment modality for tracheomalacia with short operating times and rapid recovery. Outcomes vary with the best results in the TOF and premature groups. Careful patient selection and MDT work-up are essential to optimize outcomes.
