摘要
目的 应用彩超评价小儿动脉导管未闭封堵术的疗效。方法 2 2例动脉导管未闭 (PDA)患儿经导管用 3种方法 (弹簧圈法、蘑菇伞法、海绵塞法 )进行封堵。超声心动图检查示 17例患儿PDA为管形 ,5例为漏斗形。直径为 1.9～ 5 .2mm ,平均 (3 .5± 0 .9)mm。 6例采用蘑菇伞法 ,10例采用弹簧圈法 ,6例采用海绵塞法。分别于术前、术后 3d、1月、半年复查超声心动图 ,观察大动脉水平有无分流及心脏大小变化。结果 ①术后 3d复查 ,有 2例存在少量残余分流 ;1月后复查残余分流消失 ;半年后复查均正常。②术后心功能改善明显 ,术后 1月复查左房、左室内径和肺动脉内径均有明显回缩 (P <0 .0 0 1)。结论 经导管介入治疗小儿PDA是一种创伤小 ,疗效高 。
Objective To evaluate the efficiency of transcatheter closure of children's patent ductus arteriosus (PDA) by three mathods (Coil,Amplatzer and Porstmann methods) in 22 patients ,mean age ( 5.9 ± 4.0 ) years old.Methods Mean echo diameter of PDA was ( 3.5 ± 0.9 ) mm ( 1.9 ～ 5.2 mm),included 6 patients by Amplazer method, 10 patients by coil method and 6 patients by porstmann method. Echocardiograms were obtained in the third day before and after operation,1 month and 6 months after operation, respectively.Results A small shunt was detected in 2 patients in the third day after operation.But it disappeared after 1 month and the all cases were succeeded after 6 months.Echocardiography showed the diameter of left atrium, left ventricle, and pulmonary artery were decreased significantly in all patients(P< 0.001 ).Conclusions Transcatheter closure of children's PDA is a safe and effective method for treatment of congenital heart desease.
