用Amplatzer封堵器介入治疗房间隔缺损及动脉导管未闭(附23例报告)

Transcatheter closure of secundum atrial septal defect and patent ductus arteriosus using Amplazter device: a report of 23 cases

目的 探讨应用Amplatzer封堵器治疗先天性心脏病心房间隔缺损 (atrialseptaldefect,ASD)及动脉导管未闭 (patentductusarteriosus ,PDA)的方法并评价其疗效。方法 2 3例患者 (ASD 19例 ,PDA 4例 )。所有病例均在X线透视、造影及食道超声心动图监视下经导管置入Amplatzer封堵器治疗ASD及PDA。结果 全组技术成功率 10 0 %。 2 3例患者术后 2 4h、1周行经胸超声心动图 (TTE)检查 ,有 2例存在残余分流 ,术后即刻完全封堵率 91 2 %。术后 6个月随访TTE检查示所有病例均封堵完全 ,无残余分流 ;X线检查全部显示肺血减少 ,心胸比例不同程度缩小。结论 经导管置入Amp latzer封堵器是治疗ASD和PDA的一种操作简便、技术成功率高、疗效可靠的介入方法。

Objective To evaluate the therapeutic effect of transcatheter closure of secundum atrial septal defect (ASD) and patent ductus arterious (PDA) using Amplatzer device Methods Twenty third patients (19 ASD, 4 PDA) were treated with Amplatzer device through the pecutaneous procedure under fluoroscopy,angiography and TTE Results The success rate was 100% No residual shunts were found in 21 cases after the procedure 24 hours and 1 week later TTE and X ray examination showed that no residal shunts in all cases and both pulmonary vascularity and cardiac silhouette were improved after the procedure half a year Conclusion Transcatheter closure of ASD and PDA using Amplatzer device is an efficent method, the operation is simple with a high sucess rate and a good occlusion effect
