经胸超声心动图引导Amplatzer封堵器治疗 PDA、ASD、VSD的临床价值

目的 探讨经胸超声心动图(transthoracic echocardiography，TTE)在指导Amplatzer封堵器封堵动脉导管未闭(patent ductus arteriosus，PDA)、房间隔缺损(atrial septal defect，ASD)及室间隔缺损(ventricular septal defect，VSD)中的应用价值。方法 应用TTE对5例PDA、15例ASD及6例VSD行经导管封堵术。结果 23例患者成功地进行了封堵，术中及术后均无并发症，无残余分流。2例ASD及1例VSD未完成封堵。总的成功率为88．46％(23／26)。结论 TTE对于应用Amplatzer封堵器封堵PDA、ASD及VSD术前病例选择、指导选择封堵器型号以及在放置封堵器过程中和术后疗效评价起着重要作用，是一种有效的监测方法。

Clinical Value of Transthoracic Echocardiography Guided Amplatzer Device for Occlusion of PDA, ASD and VSD in 26 Cases

Objective To study the value of transthoracic echocardiography(TTE)guided transcatheterized Amplatzer device for occlusion of patent ductus arteriosus (PDA), atrial septal defect(ASD) and ventricular septal defect(VSD).Methods ASD in 15 cases, PDA in 5 cases and VSD in 6 cases were treated with transcatheterized Amplatzer device occlusion guided by TTE.Results Twenty three patients ( ASD in 13 cases,PDA in 5, VSD in 5) were treated with Amplatzer devices occlusion successfully and no complications and shunt flow were observed.Except 2 cases with ASD and one patient with VSD, the successful rate of occlusion was 88.46%(23/26).Conclusions TTE plays a key role of PDA,ASD, VSD in Amplatzer device selection and the effects after the operation.It is an effective monitoring method for cardiac operation.
