目的 研究Amplatzer导管封堵器 (ADO)介入闭合先天性膜周部室间隔缺损 (VSD)的可行性、安全性和有效性 ,确定其适应证和并发症。方法 2 0 0 1年 5月至 2 0 0 2年 1 2月 ,经导管闭合先天性膜周部VSD 4 1例 ,VSD直径 4～ 1 2 .8(平均 6 .0 )mm ,其上缘距离主动脉右冠瓣 4 .5～ 1 2 (平均 6 .6 )mm。心导管资料示QP/QS 1 .4～ 2 .6 (平均 1 .7) ,肺动脉收缩压 1 9～ 34(平均 2 5 )mmHg。 4 1例膜周部VSD中 ,1 8例伴有膜部膨出瘤。结果 4 1例VSD均顺利闭合成功 ,选用的ADO尺寸为 6 / 4～ 1 6 /1 4mm。术后心脏杂音立即消失 ,选择性左心室造影及经胸超声心动图均无明显残余分流。胸片示肺血管影较术前减少。心电图有 1 2例出现不完全性右束支传导阻滞 ,1例出现完全性左束支传导阻滞 ,均在 1～ 2周内自行消失。随访 2～ 2 1个月 ,临床及实验室资料进一步改善 ,未见ADO移位、主动脉瓣或三尖瓣返流及其他并发症。结论 用ADO介入闭合先天性膜周部VSD是完全可行的 ,而且具有操作简便、安全高效。
Objective To study the feasibility of congenital perimembranous ventricular septal defect(VSD) occlusion by Amplatzer duct occluder (ADO) and to establish guidelines for its safe and effective application. Methods From May 2001 to December 2002, percutaneous transcatheter occlusion of congenital peri membranous VSD was performed in 41 patients, in which 18 patients had an associated aneurysm of the membranous septum. There were 20 male and 21 female subjects, with age ranging from 6 to 38 years (median 14.9) and weights of 18 to 62 kg (median 41.5). The diameter of VSD ranged from 4 to 12.8 mm (median 6.0), and the distance of VSD to the aortic valve were 4.5 to 12 mm (median 6.6). The ratio of pulmonary to systemic blood flow (Qp/Qs) was 1.4 to 2.6 (median 1.7) and the pulmonary systolic pressure was 19 to 34 mmHg (median 25). Results All the patients underwent successfully complete occlusion of VSD with ADO, and the size of ADO ranged from 6/4 to 16/14mm. After the procedure, left ventricular angiography and transthoracic echocardiography showing the ADOs were precisely placed inside the VSDs with no residual shunt and also no abnormalities revealed by auscultation. Chest X ray showed the relief of congestion of the lungs. Electrocardiagram demonstrated complete left bundle branch block in one case and incomplete right bundle branch block in other 12 cases, all disappeared within 1 to 2 weeks. Over a period of 2 to 21 months follow up, all the devices maintained in good position and the patients' condition turned much better. No patient developed aortic or tricuspid regurgitation and other complications. Conclusions ADO is a safe, effective and convenient occlusion device which could be practically applied for the congenital perimembranous VSDs.
