Understanding the Mechanisms of Main Bronchial Compression in Patients with Intracardiac Anomalies

BACKGROUND:The study focuses on vascular compression of the main bronchus in the aortopulmonary space, examining potential contributors within the same axial plane.Its goal is to uncover mechanisms of bronchial compression in patients with intracardiac anomalies and review surgical outcomes, aiming to enhance future results. METHODS:The morphology and topology of structures within the axial plane of the aortopulmonary space were objectively analyzed, including the sternum, ascending aorta, heart, pulmonary artery, descending aorta, and other relevant elements.Identified deviations from the normal configuration were systematically identified.Operative procedures included mobilizing and removing the compressing vessel, followed by suspending the airway wall to a rigid prosthesis (external stenting), vertebra, or ascending aorta.
