摘要
目的：分析总结经胸超声下封堵器治疗房间隔缺损及测量球囊的临床应用价值。材料与方法：24例ASD行Amplatzer封堵术患者，年龄9—70岁，均在经胸B超（TIE）指导下用Amplatzer封堵器介入治疗。其中11例未经测量球囊测量，在超声指导下直接封堵。结果：球囊测量组13例，即刻完全封堵率92．3％。未经球囊测量，在超声下直接选用封堵器治疗11例，即刻完全封堵率90．9％。全组24例成功，技术成功100％，即刻完全全封堵率91．7％。其中各1例因选用封堵器欠佳，后改用更大型号封堵器封堵成功。随访2月-3年，未见残余分流及封堵器脱落，肺多血及右心房室增大较术前有不同程度改善。结论：在TIE指导下用Amplatzer封堵器治疗ASD是一种安全有效的介入治疗方法，随着临床及超声经验的积累，可不完全依赖测量球囊，采用超声判断直接选择封堵器大小。
Purpose： To evaluate the clinical result of transcatheter therapy of atrial septal defects using occluder and balloon under transthoracic echocardiography. Materials and Methods： 24 cases of ASD, age from 9 to 70, were treated using Amplatzer occluder under TIE guidance. 11 of them were occluded under TIE guidance without balloon measuring. Results： 13 of all the cases were treated after a balloon measuring the diameter with an instantaneous closure rate was 92.3%. Those treated without a balloon measuring the diameter had an instantaneous closure rate of 90.9%. All the cases were successfully treated with a technical completion rate of 100% and an instantaneous closure rate of 91.7%. One of the patients was re- occluded with a larger occluder due to improper measurement. Follow up study from 2 months to 3 years showed no remaining bridging and abscission of ocluder, in addition pneumonemia and enlargement of right comparement had been bettered. Conclusion： Amplatzer oecluder is a safe apparatus to treat ASD guided under TIE in transcatheter therapy, with sufficient experience in TIE and clinical practice, balloon measurement will not be a necessity in the therapy.
