目的 :应用国产Amplatzer封堵器经导管治疗动脉导管未闭 (PDA)患儿并对其进行评价。方法 :经股静脉递送封堵器 ,术后选择性降主动脉造影及心脏B超评价其结果。结果 :12例PDA最窄处直径为 3.0～ 8.0mm ,8例PDA封堵后即刻杂音消失 ,主动脉弓降部部造影显示无残余分流 ,3例 2d后杂音消失 ,心脏超声示心脏大小恢复正常 ;1例因导管较粗 ,压差较大 ,封堵后仍有少量渗透性残余分流 ,但复查心脏超声显示心脏较前明显减小。 3月后复查超声残余分流消失。结论 :应用国产Aamplatzer封堵伞经导管治疗中 ,大型动脉导管未闭是安全有效的介入方法 ,疗效满意
OBJECTIVE: To evaluate and evaluate the use of a domestic Amplatzer occluder for the treatment of children with patent ductus arteriosus (PDA). Methods: Transcatheter occluders were delivered through the femoral vein, and postoperative selective descending aorta angiography and heart B ultrasound were used to evaluate the results. Results: The narrowest diameter of PDA was 3.0 ~ 8.0mm in 12 cases. The murmur disappeared immediately after occlusion of 8 cases of PDA. There was no remnant shunt in the lesion of the arch of the aortic arch. After 3 days, the murmur disappeared and the heart size returned to normal after 2 days of echocardiography. One case of catheter due to coarser, larger pressure, there is still a small amount of residual residual shunt after shunt, but the review of cardiac ultrasound showed a significant reduction in the previous heart. Review after March ultrasound residual shunt disappeared. Conclusion: The application of domestic Aamplatzer plugging catheter in the treatment of large patent ductus arteriosus is a safe and effective method of intervention, with satisfactory results
