目的探讨产前超声心动图诊断中孕期胎儿肺动脉闭锁肺血供来源的意义。方法回顾性分析总结17例胎儿肺动脉闭锁产前超声心动图或引产后解剖确诊为胎儿肺动脉闭锁的超声心动图表现,总结其肺循环血供来源显示情况。结果产前超声心动图诊断胎儿肺动脉闭锁17例。获取6例标本进行病理解剖,4例侧支动脉发自动脉导管,1例侧支动脉发自于降主动脉,1例右侧侧支动脉来源于降主动脉侧支、左侧侧支动脉发自左锁骨下动脉;肺血供来源误诊2例。结论产前超声对肺动脉闭锁肺动脉血流方向、侧支血管建立的判断具有重要意义。
Objective To investigate the significance of prenatal echocardiography in diagnosing the source of pulmonary blood supply to the fetal atherosclerotic placenta during pregnancy. Methods A retrospective analysis of 17 cases of fetal pulmonary artery occlusion prenatal echocardiography or postnatal anatomy was diagnosed as fetal pulmonary artery atresia echocardiographic performance summary of the pulmonary circulation of blood supply shows the situation. Results Prenatal echocardiography diagnosis of 17 cases of fetal pulmonary atresia. Six cases were obtained for histopathological examination. Four cases of collateral artery were transcatheter arterial catheterization. One case of collateral artery was from the descending aorta and the other one was from the collateral of the descending aorta. The left collateral artery Originated from the left subclavian artery; pulmonary blood supply misdiagnosed in 2 cases. Conclusions Prenatal ultrasound is of great importance in judging the direction of pulmonary artery occlusion and the setting of collateral vessels.
