心内直视杂交封堵肌部多发室间隔缺损

目的总结心内直视杂交封堵肌部多发室间隔缺损（室缺）的经验。方法 2006年4月～2009年12月,行21例心内直视杂交封堵肌部多发室间隔缺损术。男15例,女6例。3例年龄分别为4、7和15岁;余18例平均手术年龄8个月（2～11个月）,平均体重5.8 kg（4～8 kg）。19例伴心内外畸形,包括膜周室缺、肌部流入道室缺、肺动脉瓣下室缺、房间隔缺损、动脉导管未闭、二尖瓣反流、主动脉缩窄、三尖瓣反流、冠状动脉畸形和先天性房室传导阻滞等。心内直视杂交封堵解剖纠治方法：主动脉及上下腔静脉插管,浅低温体外循环（肛温32～34℃）,阻断主动脉,右心房切口,经由房间隔径路探及肌部室间隔缺损,经缺损右室面过导引钢丝及鞘管,导入封堵器行肌部室缺封堵器封堵。伴心内畸形者,行同期纠治。结果手术无死亡,食道彩超无影响心功能的明显残余分流。1例术后发生肺动脉高压危象,术后3天延迟关胸。术后随访6个月～3年,无死亡,2例术后心尖部小缺损开放,7例封堵器边缘残留少量左向右分流。全组左心室射血分数0.64±0.04,左心室缩短率35%±4%,心功能正常。结论心内直视杂交封堵肌部多发室间隔缺损,可避免传统手术纠治需心室切口、心室内肌束切开和残余分流率高、对心功能影响大的缺点;且可缩短体外循环时间,并同期纠治伴发畸形,手术简便、安全,尤其适用于婴幼儿,可获得较佳近中期疗效。

Hybrid Approaches under Direct Vision for the Management of Muscular Ventricular Septal Defects

Objective The purpose of this study is to describe our experience in hybrid approaches for the management of muscular ventricular septal defects(mVSDs). Methods From April 2006 to December 2009,we used hybrid approaches in 21 patients with mVSDs(15 male and 6 female).Eighteen of the patients aged 2 to 11 months(mean,8 months) with a mean weight of 5.8 kg(4-8 kg),and the other three aged at 4,7,and 15 years respectively.Nineteen of the patients were complicated with intra-or extracardiac malformations includ...
