经导管Amplatzer封堵器堵闭小儿房间隔缺损46例报告

Transcatheter closure of atrial septal defects with Amplatzer septal occluder.

目的 探讨应用Amplatzer封堵器堵闭小儿房间隔缺损 (ASD)的可行性。方法 46例ASD患儿 ,年龄 2～ 15岁 ,平均 (7 5± 4 2 )岁 ,在基础麻醉下 ,先行右心导管用测量球囊导管测量ASD大小 ,选择适合的封堵器 ,在超声指导下放出封堵器堵闭ASD ,然后监测封堵器位置是否满意、有否残余分流、房室瓣有否累及 ,以达到完全堵闭效果。结果 46例全部成功 ,无一例有合并症 ;手术时间 (6 5 88± 2 0 78)min ,透视时间 (11 0 5± 4 0 4)min。结论 经导管AmplatzerASD堵闭术是一种安全、有效的方法 ,适用于 2岁以上、缺损口在 30mm以下的继发孔ASD患儿。但必须严格掌握适应证 ,术中必须应用经胸超声心动图或食道超声帮助提高堵闭术的成功率 。
