经皮导管弹簧圈封堵动脉导管未闭疗效观察

目的　评价两种弹簧圈在封堵动脉导管未闭（ＰＤＡ） 中的疗效。方法　分别用Ｃｏｏｋ 可控弹簧圈及普通弹簧圈经导管法封堵治疗ＰＤＡ 共１８ 例。结果　Ｃｏｏｋ 可控弹簧圈一次性封堵成功１１ 例，二次封堵成功２ 例；普通弹簧圈一次性成功２ 例，３ 例封堵失败，其中２ 例弹簧圈移位后行ＰＤＡ 结扎术。结论　Ｃｏｏｋ 可控弹簧圈封堵ＰＤＡ，避免了无传递装置易致弹簧圈移位和脱落的缺点，对较小的ＰＤＡ是一种安全、有效、方便的非开胸手术方法。

Advantage of percutaneous transcatheter detachable coil occlusion of patent ductus arteriosus in children

Objective To compare the effects of two different types of coil on patent ductus arteriosus (PDA) closure.Methods The detachable coil was used in 13 PDA cases and the gianturco coil was used in 5 cases as control. The transcatheter was performed in all the 18 cases.Results PDA was successfully closed in all cases who used the detachable coil (11 with one coil and 2 with a second coil), while success was obtained in 2 cases who used the gianturco coil. Conclusions The percutaneous transcatheter detachable coil for small PDA clousre is safer, more effective, easier to handle and less invasive.
