国产封堵器治疗嵴内型室间隔缺损的近远期效果观察
Medical Journal of the Chinese People's Armed Police Forces(2014)
Abstract
目的:探讨应用国产封堵器经导管介入封堵治疗嵴内型室间隔缺损( intracristal ventricular septal defect,IVSD)的近期及远期效果。方法2005-07至2010-12经超声心动图初诊43例IVSD患者,男24例,年龄3~21岁,女19例,年龄10~28岁,超声测量直径平均(4.5±2.8) mm(3~8 mm)。按常规方法建立股动脉-室间隔-股静脉的轨道行介入治疗,选用国产封堵器治疗。结果43例患者最终确诊为IVSD,其中有2例转心外科治疗,1例合并主动脉缩窄,另1例合并右室流出道狭窄。有3例介入手术未成功,成功封堵的38例中术后有3例主动脉瓣微量反流,随访平均6.5年(4~9年),期间仍有1例患者主动脉瓣微量分流。封堵器无移位,无心律失常。结论国产封堵器介入治疗嵴内型室间隔缺损效果肯定,成功率高,残余分流及封堵器移位发生率低,远期随访疗效可靠。
