Insights
Severe tracheal stenosis in young children can be successfully treated with surgical reconstruction. This study highlights successful outcomes for two pediatric patients with congenital tracheal malformations, demonstrating the efficacy of extracorporeal circulation and interdisciplinary care.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Congenital Malformations
Background:
- Severe tracheal stenosis is a life-threatening condition in infants requiring prompt surgical intervention.
- Congenital stridor can indicate underlying tracheal malformations necessitating thorough investigation.
Observation:
- Two pediatric patients (1 and 2 years old) presented with critical respiratory distress due to tracheal stenosis following infections.
- Diagnostic workup revealed a pulmonary artery sling with tracheal compression and hypoplasia in one patient, and localized tracheal stenosis in the other.
Findings:
- Both patients underwent surgical reconstruction of the lower airways using extracorporeal circulation via midline sternotomy.
- One patient had tracheal enlargement with a pericardial patch for hypoplasia, while the other had resection and direct anastomosis for localized stenosis.
- Both children survived with good clinical outcomes at 18 and 9 months post-surgery, with excellent tracheobronchoscopic results.
Implications:
- Surgical reconstruction of congenital lower airway malformations in young children is feasible and effective using extracorporeal circulation.
- Successful outcomes depend on meticulous surgical technique and strong interdisciplinary collaboration between specialists.
- This approach offers a viable solution for life-threatening pediatric tracheal stenosis, improving patient survival and quality of life.
Abstract:
Severe tracheal stenosis represents a life threatening malformation which necessitates early surgery. Two patients aged one and two years, respectively, were followed-up for signs of congenital stridor. Following respiratory infection both children became critically ill with severe dyspnoea necessitating intubation and artificial ventilation. In the first patient, echocardiography, tracheobronchoscopy and other investigations revealed a pulmonary artery sling with tracheal compression and hypoplasia of the whole trachea. In the second child, presence of a short local tracheal stenosis was found, the cause of which could not be clarified. In the patient with the pulmonary sling, resection and reimplantation of the anomalous left pulmonary artery was performed first. In both children, however, surgical reconstruction of the lower airways was necessary. Surgery was performed from a midline sternotomy approach in extracorporeal circulation. The hypoplastic trachea with circular rings in the first child was enlarged with a pericardial patch. In the second child, the local tracheal stenosis was resected and a direct anastomosis of the trachea was performed. In both patients, transient formation of granulations was observed. Both children, however, survived and their clinical condition remains good 18 and 9 months, respectively, after surgery. Tracheobronchoscopic controls show very good result. Our experience confirms the possibility of successful surgical reconstruction of lower airways in young children using extracorporeal circulation. Good interdisciplinary cooperation between the surgeon and other specialists is an important prerequisite of good surgical results.
