Abstract
Tracheal stenosis in combination with vascular and/or cardiac anomalies is a life-threatening condition in infants and children presenting with severe symptoms of airway obstruction. The optimal surgical treatment of these cases remains controversial. We present here a group of infants and children with combined tracheal malformations and vascular and/or cardiac anomalies. More than 30 % of the stenotic trachea was resected in a subgroup of the patients. A reconstruction with end-to-end anastomosis was achieved on the basis of extensive mobilization of the whole tracheobronchial tree and use of CPB. The clinical outcome in 37 children with a median age of 8 (1 - 72) months was analyzed retrospectively. The patients presented with severe airway obstruction in combination with congenital heart defects and/or vascular anomalies. Cardiac catheterization, bronchoscopy and thoracic computer tomography were performed prior to operation. The operations were performed under CPB and consisted of tracheal resection with end-to-end anastomosis or external stabilization. Associated intracardiac and vascular anomalies were repaired simultaneously. All but 1 patient survived and had a straightforward recovery. The patients were extubated under bronchoscopic control with a median intubation time after airway repair of 12.2 days. The average follow-up was 8.4 years (1 - 14 years) and the surviving patients did not show signs of restenosis clinically. A segment longer than 30 % of the tracheal length was resected and reconstructed with end-to-end anastomosis in 57 % of the patients (12 of 21 patients). Our experience demonstrates that resection of tracheal stenosis and end-to-end anastomosis can be achieved successfully even in cases with stenosis of more than 30 % of the total tracheal length. The use of CBP allowed extensive mobilization of the tracheobronchial tree and resection with end-to-end tension-free anastomotic reconstruction.
