Abstract：Objective To evaluate the value of Doppler echocardiography in the diagnosis of left lower -lobe pulmonary artery sling ( LLPAS) , and to analyze the misdiagnosed reason so as to improve the correct rate of diagnosis in the future .Methods Doppler echocardiography was performed and these images were compared with CT and surgical findings in 9 patients.Results In 9 cases with LLPAS, 6 cases (66.67%) were diagnosed correctly,3 cases (33.33%) were misdiagnosed.In misdiagnosed cases, 2 cases were misdiagnosed as left pulmonary artery dysplasia , 1 case was missed diagnosis.In 9 cases, 6 cases presented with artrial septal defect or patent foramen oval , 5 cases with ventricular septal defects , 4 cases with pulmonary artery hyperten-sion, 3 cases with aortic valve stenosis , 2 cases with coarctation of aorta , 2 cases with patent ductus arteriosus .Tracheobronchial stenosis was shown in 3 children.Conclusion Left lower-lobe pulmonary artery sling could be diagnosed by doppler echocardio-graphy , but it was prone to be misdiagnosed .
