摘　　要：目的　评价Amplatzer封堵器治疗动脉导管未闭 (PDA)的疗效。　方法　经导管置入Amplatzer封堵器施行PDA封堵术 2 2例 ,术前均经胸超声心动图 (TTE)检查确诊。术后 3天、3个月分别行TTE检查以评估疗效。　结果　 2 2例均获成功 ,术后即刻所有患者心前区连续性杂音消失 ,15min后胸主动脉造影示 18例 (81.8% )动脉导管完全封闭 ,4例有微量或少量的残余分流。术后 3天TTE检查示 9例有由左向右的少量分流 (一年后完全消失 ) ,3个月后TTE随访检查仅发现 1例存在微量分流 ,所有病例左心室直径均缩小 ,未发现封堵器移位、动脉导管再通或肺动脉狭窄等 ;除 1例出现少量心包积液外 ,未发现其他并发症。　结论　应用Amplatzer封堵器治疗PDA操作简便、成功率高、适应证广 。Objective To evaluate the efficiency of transcatheter closure of patent ductus arteriosus(PDA) using Amplatzer occluder device. Methods Twenty two patients with PDA were treated by transcatheter closure using Amplatzer occluder device.All patients were diagnosed definitely by transthoracic echocardiography(TTE) before the procedure. TTE was performed at 3 day and 3 mnths after the procedure, respectively. Results No continuous murmur was heard in all patients instantly after the procedure. Aortography showed that the lesions were closed completely in 18 cases (81.8%), only a little residual shunt remained in four cases 15 minutes after the procedure. TTE revealed that only one patient had a little residual shunt at 3 months after procedure,and disappeared at one year. No complication was found in all patients except one who had pericardial effusion. In a follow up of 3 months, no device displacement, recanalization of ductus arteriosus and pulmonary stenosis appeared. Conclusion Transcatheter closure of PDA using Amplatzer occluder device has high rate of success,wide indication, and little trauma. Therefore,it is an ideal procedure in treatment of PDA at present.
