ABSTRACT
Objective：To improve the echocardiographic（Echo)diaghostic and differential diagnostics accuracy of pulmonary atreia（PA)
Methods：The data of Echo in patents with PA were analyzed retrospecfively. The results of ultrasounic examination were compared with surgical findings and Echo.
Results：①7 cases were accurately diagnosed by Echo，misdiagnosed of main diagnosis by Echo accurred in three cases of them. ②Pulmonary atresia with integrity of ventricular septum（PA－IVS)often had hypoplastic right heart syndrome. ③Source of pulmonary blood supply were many kinds. If main pulmonary have forward blood flow，It can be misdiagnosed as pulmonary stenosis. ④PA was complexed by deformity of many kinds.
Conclusions：PA can be diagnosed by Echo. If suspicious diagnosis of PA though poor in imaging quality，we should combine contrast Echo with angiocardiography to get accuracy diaguosis.

肺动脉闭锁在临床上相对少见，依据室间隔完整性分为室间隔缺损型肺动脉闭锁（PA－VSD)和室间隔完整型肺动脉闭锁（PA－IVS)。本文回顾分析了11例肺动脉闭锁患者的超声心动图特点和诊断和鉴别诊断要点。 |
