目的 对应用Amplatzer封堵器治疗继发孔型房间隔缺损和动脉导管未闭的疗效进行初步评价。方法 房间隔缺损患儿 4例 ,在透视及彩色二维超声心动图监视下经导管置入Amplatzer封堵器封堵房间隔缺损。动脉导管未闭患儿 7例 ,在透视下经 6F输送器置入Amplatzer封堵器 ,术后 10分钟主动脉弓降部造影。所有病例均在术后 48小时、1月、3月、6月、1年、2年分别行超声心动图检查评价疗效。结果 11例患儿中 ,除 1例房间隔缺损术后 48小时超声心动图显示有残余分流外 ,其余均完全闭合 ,5例随访 2年、3例随访 6个月未见任何并发症。结论 应用Amplatzer封堵器经导管治疗房间隔缺损、动脉导管未闭是安全、有效的介入方法 ,近期疗效满意
Objective To evaluate the efficacy of Amplatzer occluder in the treatment of secondary atrial septal defect and patent ductus arteriosus. Methods Four cases of atrial septal defect were treated with Amplatzer occluder under fluoroscopy and color two-dimensional echocardiography to block atrial septal defect. 7 cases of patent ductus arteriosus, under the perspective of the 6F conveyor into the Amplatzer occluder, 10 minutes after the aortic arch angiography. All cases were evaluated by echocardiography after 48 hours, January, March, June, 1 year and 2 years respectively. Results All the 11 cases were completely closed, except for 1 case of atrial septal defect 48 hours after echocardiography showed residual shunt, 5 cases were followed up for 2 years, 3 cases were followed up for 6 months without any complications. Conclusions Transcatheter closure of atrial septal defect and patent ductus arteriosus with Amplatzer occluder is a safe and effective interventional method. The short-term curative effect is satisfactory
