Clinical analysis of 145 cases of pediatric pulmonary artery sling diagnosed by echocardiography

This study explored echocardiography's role in diagnosing and managing pediatric pulmonary artery sling (PAS). Data from 145 patients (January 2017 to December 2023) were analyzed, including echocardiography, CT angiography, bronchoscopy, and surgical records. Results indicated echocardiography accurately diagnosed PAS in 98.62% cases, with 1.38% misdiagnosed. Tracheal compression was common (95.86%), along with intracardiac anomalies (73.79%). Combined vascular ring types were found, notably PAS with left aortic arch and aberrant right subclavian artery (LAA-ARSA) and PAS with double aortic arch (DAA). Echocardiography's effectiveness underscores its crucial role in clinical management and surgical planning for these complex conditions.
