目的: 观察彩超对蘑菇伞器堵闭PDA 的疗效。方法: 全组18 例, 年龄1.5～10 岁, 平均5.6 岁。彩超测PDA 最窄直径1.3～6m m , 平均4.2m m 。经导管介入治疗后对弹簧圈及蘑菇伞器封堵后状况进行观察。立即、24 小时、3 月, 了解封堵状况及疗效。结果: 弹簧圈器法仍有微量残余分流, 蘑菇伞器法未见残余分流。房室大小及分流状况均已恢复正常。结论: 蘑菇伞器法封堵PDA 操作简便、疗效显著、成功率高。是目前导管介入治疗PDA 的首选器材
OBJECTIVE: To observe the effect of ultrasound on the closure of PDA by mushroom umbrella. Methods: The whole group of 18 patients, aged 1.5 to 10 years, mean 5.6 years. Ultrasonography PDA narrowest diameter of 1.3 ~ 6m m, an average of 4.2m m. Transcatheter intervention after the coil spring and mushroom umbrella sealing condition was observed. Immediately, 24 hours, March, to understand the sealing condition and efficacy. Results: There was still a slight residual shunt in the coil spring method, no residual shunt was found in mushroom umbrella method. Atrioventricular size and shunt status have returned to normal. Conclusion: Mushroom umbrella method blocking PDA is simple and effective, significant effect, high success rate. Is the preferred catheter interventional treatment of PDA equipment
