目的：探讨Amplatzer栓子治疗动脉导管未闭的临床疗效。方法：对经Amplatzer栓子治疗的3例动脉导管未闭病儿的临床资料进行回顾性分析。结果：3例动脉导管未闭的最狭窄处直径2 mm至6 mm，在透视下经6 F 输送管置入Amplatzer栓子，心脏双期连续性杂音术后均即刻消失，主动脉弓降部造影1例显示少量云雾状分流，2例显示无分流。术后48小时UCG显示3例动脉水平分流完全消失。结论：应用Amplatzer栓子治疗动脉导管未闭效果满意，具有非开胸、无瘢痕、操作简便等优点，是安全有效、值得推广的介入方法。
Objective: To investigate the clinical efficacy of Amplatzer embolectomy for patent ductus arteriosus. Methods: The clinical data of 3 cases of patent ductus arteriosus treated with Amplatzer emboli were retrospectively analyzed. Results: The diameter of the narrowest 3 cases of patent ductus arteriosus was 2 mm to 6 mm in diameter. Amplatzer emboli were inserted through the 6 F delivery tube under fluoroscopy. Immediate bilateral cardiac murmur disappeared immediately after continuous murmur. Cases showed a small amount of cloud-like shunt, 2 cases showed no shunt. UCG at 48 hours postoperatively showed complete disappearance of the arterial shunt in 3 cases. Conclusion: The application of Amplatzer embolization in the treatment of patent ductus arteriosus is satisfactory, with the advantages of non-thoracotomy, no scars and simple operation, which is safe and effective and worthy of promotion.
