Objective To evaluate the clinical value of computer tomography angiography( CTA) in the diagnosis of anomalous pulmonary artery.
Methods Clinical data of 9 patients with anomalous pulmonary artery diagnosed by CTA were retrospectively analyzed, and CTA results were compared with those of echocardiographic examination.
Results CTA clearly demonstrated the origin sites and topography of anomalous pulmonary arteries in all 9 patients. One patients presented with left pulmonary artery sling, and 8 patients presented with anomalous right pulmonary artery which originated fromthe proximal ascending aorta. Among them1 patient was with isolated anomalous origin of right pulmonary, and the others were complicated with patent ductus artery( 5 cases) , ventricular septal defect ( 3 cases) , and aortopulmonary septal defect ( 1 case) , etc.
Conclusions CTA is highly valuable in the diagnosis of anomalous origin of pulmonary artery and associated abnormities by clearly developing the pathologic anatomic features and complicated cardiovascular malformations
