改良Bjork手术治疗三尖瓣闭锁12例

目的 观察改良Ｂjord手术治疗三尖瓣闭锁的效果。方法 自１９９６年３月至１９９９年６月，对１２例三尖瓣闭锁患儿实施了改良Ｂjord手术，即应用剖开的带瓣肺动脉片作前壁的右房右室连接术。结果 术后患儿中心静脉压（ＣＶＰ）低、胸液量少；术后血流动力学监测肺动脉为搏动性血流；超声心动图发现残存的右心室腔有收缩功能、右室腔有所增大、同种瓣叶有一定的抗反流作用。结论 改良Ｂjord手术 ，术后同种瓣有一定的抗反流作用

THE TREATMENT OF 12 CHILDREN WITH TRICUSPID ATRESIA BY MODIFIED BJORK PROCEDURE

Objective To determine the results of the patients who had been performed the modified Bjork procedure. Method 12 children with tricuspid atresia underwent the modified Bjork procedure: atrinventricular connection with a flap of valved pulmonary homograft. Results The patients had got better outcome with lower right atrial pressure, less pleural effusion. And the quantitative twodimensional ochocardiography studies showed that the right ventricular cavity were larger and had the potential to be a functional cavity, In addition, the homopulmonary valves were in function and had no pressure gradient or regurgitation. Conclutions If the split cryopreserved valved pulmonary artery patch were used as the anterior wall of the RA to RV communication, the tunnel would be growing and the valve of the homograft and the hypoplastic right ventricle would be on function.
