| 目的 探讨超声心动图对小儿主动脉缩窄的诊断价值。 方法 经超声心动图诊断的主动脉缩窄50例,男33例,女17例,年龄5天~11岁(中位年龄9个月零9天),均经手术和(或)造影证实。超声心动图检查在胸骨上主动脉弓长轴切面观显示主动脉弓及其三分支,确定缩窄范围和类型。彩色多普勒超声心动图显示主动脉缩窄处血流,频谱多普勒测量缩窄处血流速度。 结果 50例患儿中,局限性缩窄23例,占46.00％;管状缩窄27例,占54.00％;33例合并动脉导管未闭。 结论 将小儿主动脉缩窄分为管状缩窄和局限性缩窄可能更为合理;管状主动脉缩窄较常见。 |

| Objective To assess the value of echocardiography in diagnosing coarctation of the aorta (CoA)in children. Methods Aortic arches and the three branchs were displayed, and CoA was diagnosed and classified with echocardiography in 50 cases, while blood flow velocity was measured with color Doppler flow imaging. Results Discrete coarctation was found in 23 cases (46.00%), whereas tubular coarctation was detected in 27 cases (54.00%) of CoA. In all the 50 cases of CoA, 33 complicated with PDA. Conclusion It seems better to classify CoA into discrete coarctation and tubular coarctation. Tubular coarctation of CoA in children is more than discrete coarctation. |
