Translational value of partial resection of the pulmonary artery wall for congenital heart disease-induced bronchial compression

OBJECTIVE: This study was performed to evaluate the clinical efficacy and safety of a novel surgical procedure in treating tracheal or bronchial compression related to severe congenital heart disease. METHODS: The clinical data of 28 patients with tracheal or bronchial compression related to severe congenital heart disease were retrospectively analyzed. In the control group, 12 patients underwent surgery for congenital cardiac malformations. In the treatment group, 16 patients underwent surgery for congenital cardiac malformations combined with partial resection of the pulmonary artery wall. The cardiothoracic ratio, pulmonary arterial pressure, left ventricular end-diastolic dimension, diameter of the pulmonary artery, and diameter of the trachea in the stenotic segment were quantitatively measured before and 9 days after the operation. RESULTS: The diameter of the pulmonary artery and diameter of the trachea in the stenotic segment were almost restored to the normal range in the treatment group. Patients in the treatment group recovered more rapidly and effectively than those in the control group. CONCLUSION: Partial resection of the pulmonary artery wall is an efficacious and safe technique in the treatment of tracheal or bronchial compression related to severe congenital heart disease.
