应用Cook可控弹簧栓子封堵动脉导管未闭

目的 :应用 Cook可控弹簧栓子封堵动脉导管未闭 （PDA）并对其疗效进行评价。方法 :全组共 10例 ,年龄 2～ 35 （平均 11.6 ）岁 ,体重 8～ 6 4（平均 30 .6 ） kg,PDA最窄处直径 1.4～ 3.2 （平均 2 .6 ） m m。经导管置入 Cook可控弹簧栓子封堵 PDA。封堵后 10 min行胸主动脉造影评价疗效。术后 3天、1月、6月及 12月行超声心动图检查观察有无残余分流及 PDA再通。结果 :全组技术成功率为 10 0 % ,术后 10 m in胸主动脉造影及术后 3d超声心动图未见残余分流。随访 12个月 ,均未发现 PDA再通及弹簧栓子移位。结论 :应用 Cook可控弹簧栓子封堵小型 PDA是一种安全、有效的非手术方法

Transcatheter closure of patent ductus arteriosus with Cook controllable coils

AIM: To evaluate the treatment efficiency of transcatheter closure of patent ductus arteriosus (PDA) using Cook controllable coils. METHODS: Ten patients with PDA, with the age from 2 to 35 years (mean 11.6 years) and the weight from 8 to 64 kg (mean 30.6 kg), were occluded with Cook controllable coils.The narrowest diameter of PDA was from 1.4 to 3.2 mm (mean 2.6 mm).The aortographies were made to evaluate the efficiency during 10 min after the procedure. Echocardiographies were performed in 3 d, 3 mo, 6 mo and 12 mo after the closure to find whether there was residual shunt and recanalization. RRESULTS: The technique successful rate of the group was 100%. No residual shunt was found in aortographies during 10 min and echocardiographies in 3 d after procedures. No coil embolization and PDA recanalization after the complete closure were found in following up for 12 mo. CONCLUSION: Transcatheter closure of small PDA using Cook controllable coils was a safe and efficient nonsurgical method.
