Methods: From July 1995 to October 1999, 88 children (38 girls, 50 boys) with TF were enrolled in this study. EBCT examinations provided information needed to plan management. The final diagnoses of airway abnormalities were correlated with the findings of bronchoscopy in five patients and confirmed during surgery. Results: Fourteen (16%) of the 88 patients had associated primary tracheobronchial anomalies. Nine patients had tracheal bronchi, which were combined with tracheobronchial stenosis in two patients and with tracheal stenosis in one patient. Two patients had tracheal diverticulum, which was combined with lower tracheal stenosis in one patient. Two patients had congenital tracheal stenosis. Tracheomalasia was found in one patient. Three patients with ventilation difficulties died postoperatively. Special attention was given to the care of the diseased airways perioperatively, and the remaining 11 patients had a smooth course of hospitalization and discharge. Conclusions: Our results show that EBCT provides good delineation of both cardiac and tracheobronchial anomalies and suggest that it should be used perioperatively to detect associated airway anomalies in TF, to facilitate the design of an appropriate ventilation care strategy.[SDGs]SDG3adolescent; article; breathing disorder; bronchoscopy; bronchus stenosis; child; diagnostic value; diverticulosis; electron beam tomography; Fallot tetralogy; female; heart disease; hospital discharge; hospitalization; human; infant; major clinical study; male; newborn; patient care; perioperative period; preoperative evaluation; respiratory tract disease; surgical mortality; trachea disease; trachea stenosis; trachea surgery; tracheobronchial tree; tracheomalacia; treatment planning; Adolescent; Bronchi; Child; Child, Preschool; Female; Humans; Infant; Infant, Newborn; Male; Tetralogy of Fallot; Tomography, X-Ray Computed; Tracheajournal article112652562-s2.0-0035102403
