AbstractBronchoscopy-guided aortopexy is a surgical management option for patients with central airway obstruction after congenital heart surgery. This study aimed to evaluate the usefulness of bronchoscopy-guided aortopexy based on midterm follow-up evaluation with computed tomography (CT) and clinical outcome. From January 2004 to August 2011, bronchoscopy-guided aortopexy was performed for 16 patients (median age 0.5 years, M:F = 10:6) who had central airway obstruction caused by extrinsic compression (13 in the left main bronchus, 2 in the trachea, 1 in the diffuse trachea and bronchus) after congenital heart surgery. The surgical site for aortopexy was determined by the anatomic relationship between the aorta and the compressed bronchus according to preoperative CT and intraoperative bronchoscopy. The median follow-up period was 2.3 years. The ratios of the diameter and area of stenosis at the narrowed point were estimated using pre- and postoperative CT. Almost all the patients (15/16) showed relief of their preoperative symptoms. The median extubation time was 18 h. The stenosis diameter and area ratios significantly improved, as shown by with the immediate postoperative CT (7.7-48.5%, p = 0.003; 54.8-80.5%, p = 0.006). Airway stenosis of more than 75% (p = 0.013), immediate diameter ratio improvement of <50% (p = 0.015), preoperative severe respiratory insufficiency (p = 0.038), and male sex (p = 0.024) were associated with recurrent minor respiratory susceptibility. Bronchoscopy-guided aortopexy is a safe and reliable surgical management choice for central airway obstruction after congenital heart surgery. Furthermore, airway improvement after aortopexy was maintained during the midterm follow-up evaluation, according to CT measurements.
