Abstract:
Objective Evaluating the imaging value of dual source computer tomography angiography (DSCTA) in diagnosis of anomalous origin of one pulmonary artery.Methods Clinical data of 13 patients with anomalous pulmonary artery diagnosed with DSCTA were retrospectively analyzed,and compared with data of echocardiography examination.Results The anomalous pulmonary was clearly diagnosed with DSCTA,which all originated from ascending aorta (AAO).Thirteen cases presented with anomalous right pulmonary artery.Of the total,11 cases originated from the proximal AAO,and 2 cases originated from the distal AAO.One patient was only with anomalous origin of right pulmonary.11 were complicated with PDA,7 were complicated with aortopulmonary septal defect and interruption of aortic arch(A type),1 case was complicated with dysplasia of aortic arch,1 case was complicated with aberrant right subclavian arteries,1 case was complicated with tetralogy of fallot(TOF),and 5 were complicated with right-sided aortic arch and right-sided descending aorta.Eight cases with anomalous pulmonary were diagnosed with echocardiography,3 cases were suspected,and 2 cases were missed.One case was complicated with TOF,5 cases were complicated with aortopulmonary septal defect,interruption of aortic arch (A type) and patent ductus artery (PDA),and 10 cases were complicated with moderate-severe regurgitation of tricuspid.In the 7 operative patients,there were consistent with DSCTA,the anomalous pulmonary and the complicated deformities were rectified.Conclusion DSCTA owns a high value in diagnosis of anomalous origin of pulmonary artery and complicated abnormities by clearly developing the pathologic anatomic features and cardiovascular malformations.
