目的:评价小腰大边型封堵器治疗膜部瘤型VSD?的安全性及可行性。方法:收集2010年1月～2011年10月在我院行介入治疗的膜部室间隔缺损的患者42例,均应用7～10F输送鞘管从右心系统送入小腰大边封堵器,封堵后15分钟重复左心室造影和经胸心脏超声波检查,观察封堵的即刻效果。术后连续心电监护2小时;术后1、3、6个月定期行心电图、心脏超声检查。结果:42例中39例患者封堵成功,成功率97.5%。39例术后15分钟左心室造影、经胸心脏超声检查显示完全封堵,2例术后即刻造影示少量分流,1～6个月后超声复查,无异常分流。术中并发右束支传导阻滞、I度房室传导阻滞分别为1和1例,均为一过性,1周内恢复。X线透视时间10～65分钟,平均15.2±8.8分钟;操作时间35～120分钟,平均42.5±16.2分钟。结论:小腰大边型封堵器治疗膜部瘤型VSD?是安全、可行的。
Objective: To evaluate the safety and feasibility of the treatment of membranous neovascular VSD with a small occlusion occlusion device. Methods: Forty-two patients with membranous ventricular septal defect who underwent interventional therapy in our hospital from January 2010 to October 2011 were collected, 15 minutes after closure of the left ventricular angiography and transthoracic echocardiography to observe the immediate effect of occlusion. After continuous ECG 2 hours; 1, 3, 6 months after the regular ECG, cardiac ultrasound. Results: In 42 cases, 39 cases were successfully blocked with a success rate of 97.5%. Thirty-nine patients underwent left ventricular angiography at 15 minutes after operation. The thoracic and cardiac ultrasonography showed complete occlusion. Two patients showed small shunt immediately after operation and ultrasound examination after 1 to 6 months without abnormal shunt. Intraoperative right bundle branch block, I degree atrioventricular block were 1 and 1, were transient, recovery within 1 week. X-ray fluoroscopy time 10 to 65 minutes, an average of 15.2 ± 8.8 minutes; operating time 35 to 120 minutes, an average of 42.5 ± 16.2 minutes. Conclusion: It is safe and feasible to treat the membranous neovascular VSD with small occlusion occluder.
