【摘要】 目的探讨应用经导管封闭治疗小儿房间隔缺损的临床效果。方法16例ASD患儿。男6例,女10例;年龄2~14(8±4)岁,体重10~40(23±9)Kg。先行右心导管用球囊导管测量ASD大小,选择适合的封堵器,在X线及超声引导下释放封堵器堵闭ASD,术后随访疗效,追踪残余分流率和并发症。结果应用此法封闭16例ASD,全部成功。手术时间为(70±30)min,透视时间(13±8)min,术中无明显并发症。术后随访右房、右室径较术前明显缩小,恢复正常(P<0.05);无残余分流发生。结论经导管封闭治疗小儿房间隔缺损术具有创伤小,成功率高,安全性好的优点,但其长期疗效需进一步随访观察。更多还原

【Abstract】 Objective: To evaluate the clinical effectiveness of the transcatheter closure of children with secundum atrial septal defects(ASD). Methods: 16 children (6 males and 10 females) with ASD, aged 2 to 14(8±4), body weight 10 to 40(23±9) kg, were enrolled in this study. Right heart cathterization was performed and ASD diameter was measured by balloon. The size of device was selected according to the stretch diameter of ASD. The device released under fluoroscopy and TTE. All patients were followed up. Results: The transcatheter closure in all cases was successful. Operation time is (70±30) min and fluoroscopy time is (13±8) min. The complication was seldom. RA diameter and RV diameter significantly decreased after procedure and decreased further during the follow-up. The occluder location is good and no residual shunt was found. Conclusions: Transcatheter closure of children with ASD is an efficient method, the operation is safe and simple with a high success rate and a good occlusion effect. It′s long-term effect should be followed up.更多还原
