摘要
目的 应用超声心动图评价＂杂交＂手术治疗婴幼儿重度肺动脉瓣狭窄的疗效,并探讨超声心动图在治疗中的应用价值.方法 回顾性分析43例超声引导下＂杂交＂手术治疗重度肺动脉瓣狭窄患儿术前、术中、术后及随访超声心动图资料.结果 在超声心动图引导下,43例＂杂交＂手术均成功完成,未出现严重并发症.超声测量肺动脉跨瓣压差由术前（92.5±21.4）mm Hg 降至（23.6±13.0）mm Hg（1 mm Hg=0.133 kPa）.随访27例患儿生长发育良好,无再狭窄发生,三尖瓣反流量均不同程度减轻.结论 ＂杂交＂手术方式是治疗婴幼儿重度肺动脉瓣狭窄安全有效的方法,超声心动图在术前病例选择、术中监测及术后随访中均发挥重要的作用.
Objective To evaluate the results of hybrid procedure in treating infants and children with severe pulmonary stenosis （PS） and the clinic value of echocardiography in the whole procedure.Methods Hybrid therapy was performed in 43 patients [（7.1±6.8）months,ranging 5 days to 33 months] with severe PS.The echocardiography data in the whole procedure and follow up were reviewed.Results Aided by echocardiography,the hybrid therapy was successful in 43 cases without major complication.Immediately following valvuloplasty,the gradient across pulmonary valve decreased from （92.5±21.4）mm Hg to （23.6±13.0）mm Hg （P〈0.05）.The growth and development of 27 patients in follow-up study was well.No restenosis was found and tricuspid regurgitation decreased differently.Conclusions Hybrid procedure is effective and safe for the treatment of infants and children with severe PS.And echocardiography play an important role in the whole procedure.
