1、婴幼儿主动脉缩窄一期手术治疗28例临床总结【摘要】：p 】：】目的 讨论婴幼儿主动脉缩窄一期手术的外科治疗经历。方法 28例患儿其中22例在全麻低温体外循环选择性脑灌注下行手术治疗，采用胸部正中切口；6例单存主动脉弓缩窄那么采用左后外侧切口非体外循环下行手术治疗。手术前均穿刺并术中术后监测上下肢血压，22例78.6%合并室间隔缺损和其他心内畸形：6例21.4%为单存主动脉弓缩窄；10例35.7%伴有严重主动脉弓发育不良，导管前型20例71.4%，导管后型5例17.8%，部分狭窄3例10.7%。采用缩窄段切除及对端吻合16例，缩窄段切除加扩大的端端吻合Resection with e_tende

2、d end-to-end anastomosis10例，部分补片2例。术后呼吸机辅助呼吸大于3 d，给予前列腺素E1降肺动脉高压。结果 28例手术顺利，术后下肢血压升高压差均小于20 mmHg。1例合并肺炎并呼吸功能不全，花费高，家长放弃治疗，1例心功能不全死亡，3例术后高血压口服卡托普利处理，死亡率7.14%。结论 掌握手术适应症，采用恰当手术方式，减少术后剩余缩窄，是手术成功的关键。【中图文分类号】R654.2 【文献标识码】B【关键词】：p 】：】婴幼儿主动脉缩窄手术治疗【Abstract】Objective to e_plore the infants and young childr

9、，女7例。手术年龄1个月3岁平均13.52.5个月，体重3.315.0 kg平均7.3 2 kg；22例78.6%合并室间隔缺损和其他心内畸形；6例21.4%为单存主动脉弓缩窄，10例35.7%伴有严重主动脉弓发育不良，导管前型20例71.4%，导管后型5例17.8%，部分狭窄3例10.7%所有病例均经超生心动图明确诊断，主动脉弓影像采用64排心脏大血管增强造影获得。主动脉弓发育不良的诊断标准：近端主动脉弓横部无名动脉与左颈总动脉之间直径小于等于升主动脉直径的60%，远端主动脉弓横部左颈总动脉与左锁骨下总动脉之间直径小于等于升主动脉直径的50%，主动脉峡部左锁骨以下直径小于等于升主动脉直径的40%。第 4 页 共 4 页
