Pulmonary artery sling is a rare congenital pulmonary vascular malformation, often associated with tracheal or bronchial stenosis. Surgical treatment of pulmonary artery sling with tracheal stenosis has a high risk and a relatively poor prognosis. This article aims to explore the relationship between the index of tracheal and left pulmonary artery stenosis and the surgical effect of pulmonary artery sling with tracheal stenosis. Methods: Retrospective analysis of the cases of pulmonary artery sling surgery in our center from January 2010 to December 2018. Before operation, routine cardiac enhancement CT examination was performed, and the diameter of the left pulmonary artery and the tracheal stenosis were measured on the CT tomogram respectively, and the ratio of the degree of tracheal stenosis / left pulmonary artery stenosis (T / P) was calculated, combining the surgical method and clinical prognosis analyzed and discussed.
