经导管介入性治疗动脉导管未闭68例临床疗效分析

Reports of 68 cases of transcatheter closure of patent ductus arteriosus

目的 :应用Amplatzer堵闭器经导管介入性治疗动脉导管未闭 (PDA)并对其疗效进行初步分析。方法 :于主动脉弓降部造影 ,测量PDA大小 ,在透视下经传送装置将Amplatzer堵闭器置入PDA内 ,使之在PDA最窄处固定 ,即刻或 10min后再次造影。术后 2 4h行超声心动图 (UCG)检查。结果 :全组技术成功率 10 0 %。术后 6 1例 (89 7% )即刻无分流 ;7例 (10 3% )即刻有少量残余分流 ,其中 4例术后2 4hUCG示分流消失 ;肺动脉高压者术后均有所下降。结论 :应用Amplatzer堵闭器治疗动脉导管未闭操作方法简便、治疗范围广、成功率高 。

Objective:To analyze the efficiency of transcatheter closure of Patent Ductus Arteriosus(PDA)using Amplatzer occluder device.Method:Through aortography,PDA size was measured.Every PDA was occluded using Amplatzer occluder device through the percutaneous procedure.The closure procedure was guided by fluoroscopy.Aorto graphy was performed immediately or ten minutes after.UCG was done 24 h after transcatheter closure.Result:The successful rate of technique was 100%.The trivial residual shunt was found in 7 cases(10.3%)immediately after the procedures and in 3 cases 24 h after the procedures.Pulmonary pressure decreased postoperatively in all cases with pulmonary hypertension.Conclusion:Transcatheter closure of PDA using Amplatzer occluder device was an efficient non\|surgical method.
