摘要 目的前瞻性随机对照研究经胸微创封堵与右腋下小切口直视修补治疗婴幼儿膜周部室间隔缺损(PmVSD)的疗效和随访结果。方法2010年1月至2013年1月,530例限制性PmVSD患儿纳入研究,年龄〈3岁,体质量〈15kg。应用随机数字表法随机分为两组:微创封堵组265例,采用胸骨下端小切口非体外循环经食管超声(TEE)引导,穿刺右心室游离壁,应用改良封堵器直接闭合VSD;右腋下小切口直视修补组265例,在常规体外循环(CPB)下采用右腋下小切口直视修补VSD。对比两组患儿手术成功率、手术时间、用血量、失血量、呼吸机辅助时间、ICU滞留时间、住院时间以及并发症发生率和医疗费用等指标。结果两组患儿全部得到有效治疗,均无死亡和危及生命的严重并发症。微创封堵组中10例(3.77%)封堵失败,适当延长原切口后中转常规直视手术成功修补;255例(96.23%)一次性封堵成功者中术后发生心律失常30例(11.76%),包括不完全左支传导阻滞(ILBB)3例(1.18%)、完全右束支传导阻滞(CRBB)3例(1.18%)、不完全右束支传到阻滞(IRBB)16例(6.27%)、Ⅰ度房室传导阻滞(AVB)8例(3.14%),微到少量残余分流(RS)18例(7.06%),新增三尖瓣少量反流(TR)29例(11.37%)。右腋下小切口直视修补组患儿全部成功(100%),术后心律失常116例(43.77%),包括CRBB61例(23.02%)、IRBB52例(19.62%)、临时性完全性房室传导阻滞(CAVB)和ILBB各2例(0.75%)、交界性异位心动过速(JET)1例(0.38%);微到少量RS16例(6.04%),新增少量TRll例(4.15%),心功能不全17例(6.42%)。所有患儿随访12个月以上,无新增或加重的瓣膜反流,无迟发的CAVB以及其他并发症。两组比较,最终疗效相仿。微创封堵组住院天数、手术时间 Objective To compare the treatment outcomes between minimally invasive perventricuIar device occlusion (MIPDO) and fight subaxillary incision surgical repair(RSISR) on perimembranous ventricular septal defect(PmVSD) in children less than 15 kilograms. Methods From January, 2010 to January, 2013, a total of 530 infants(age 〈3 years, weigh 〈 15 kg) with PmVSD enrolled and they were divided into two groups according to different treatment methods at random. Group 1 ( 265 cases) was arranged perventricular device closure with modified occluders through a lower partial median sternotomy under transesophageal echocardiography(TEE) guidance; group 2(265 cases) was arranged surgical repair on cardiopulmonary bypass(CPB) through a right subaxillary small incision. A prospective randomized controlled study was performed between two groups on success rate, operation time, volume of blood loss and transfusion, length of intubation and ICU stay, complications, expenses and follow-up results etc. Results All patients in two groups obtained effective treatment with no death or serious life-threatening complications. Group 1:255 cases(96.23% ) underwent successfully MIPDO. The remainder 10 cases( 3. 77% ) who failed in attempt were successfully converted to conventional open heart operation by extending the original incision. Different arrhythmias arose in 30 cases (11.76% ), including incomplete left bundle branch block (ILBB) in 3 cases (1. 18% ), complete right bundle branch block(CRBB) in 3 cases( 1.18% ), incomplete right bundle branch block(IRBB) in 16 cases(6.27% ), Ⅰ° atrioventricular block(Ⅰ°AVB) in 8 cases(3.14% ) ; trivial residual shunt(RS) in 18 cases(7.06% ) ; newly arose trivial tricuspid regurgitation(TR) in 29 cases( 11.37% ). Group 2 : All the patients( 100% ) underwent successful surgical repair through right subaxillary incision. Different arrhythmias occurred in 116 cases (43.77%), including tran
