Objective To explore the surgical treatment of anomalous origin of one pulmonary artery from ascending aorta(AOPA).Methods From May.2006 to Aug.2008,8 children with AOPA aged from 1 to 96 months and weighted from 4 to 24 kg,accepted surgical repair in Beijing Children′s Hospital.Seven of them was right pulmonary artery abnormal origin with patent ductus arteriosus and pulmonary hypertension,in which 4 cases had acleistocardia.One case was left pulmonary origin from ascending aorta and tetralogy of Fallot with pulmonary atresia.All cases were confirmed by enhanced CT.Surgery was performed by direct anastomosis under cardiopumonary bypass(CPB) except one case who accepted central shunt with 7 mm Goretex tube because of diminutive pulmonary arteries.Results There were no operative death.Re-echocardiography after 1 month leaving hospital showed that mean flow speed of anastomosis was(1.71±0.24) m/s,mean gra-dient(1.60±0.45) kPa,without any pulmonary stenosis.Conclusions AOPA can have a good result if receiving early diagnosis and treatment.But it still need long time to appraise.
