| 【】 目的 探讨超声心动图在右室双出口(DORV)大动脉转换术手术前、后的应用价值,分析误诊原因,提高诊断的准确性。方法 本文回顾性分析了160例经手术证实为DORV,并行大动脉转换术患儿的超声心动图资料,并将手术前、后的超声检查结果进行对比。结果 160例患儿中,超声术前诊断为DORV者155例(符合率96.9%),室间隔缺损部位术前诊断与手术相符者127例(符合率79.3%)。术后补片残余分流者17例,主动脉吻合口残余梗阻33例,肺动脉吻合口残余梗阻61例。术后超声提示左、右肺动脉的仅85例(检出率53%),其中右肺动脉狭窄29例,左肺动脉狭窄21例。右室流出道残余梗阻15例,左室流出道残余梗阻2例。新主动脉瓣反流程度较术前加重者114例,新肺动脉瓣反流程度较术前加重者20例。结论 术前超声心动图可以较准确地诊断DORV及其室间隔缺损的部位；术后可以较准确地评估半月瓣反流程度、补片残余分流和吻合口残余梗阻的情况,但对于肺动脉分支狭窄的检出困难。 |
