目的 探讨超声心动图诊断主动脉缩窄合并主动脉弓发育不良的准确性.方法 分析7例主动脉缩窄合并主动脉弓发育不良患儿的二维超声图像,并与心血管造影,心脏CT及手术结果对比分析,总结其诊断要点.结果 除主动脉缩窄的超声表现外,超声特异表现为:胸骨上凹主动脉弓长轴切面可见主动脉横弓部及弓降部明显变窄.发育不良的范围可自无名动脉起始后或左颈总动脉起始后;发育不良主动脉弓的内径/膈肌处降主动脉胸段的内径<0.5;多普勒测定主动脉缩窄处血流速度均在正常范围.超声诊断均与心血管造影、心脏CT及手术结果相符.结论 超声心动图诊断丰动脉缩窄合并主动脉弓发育不良具有较高的准确性,在主动脉缩窄的诊断中.应提高对合并主动脉弓发育不良的认识.
目的 探討超聲心動圖診斷主動脈縮窄閤併主動脈弓髮育不良的準確性.方法 分析7例主動脈縮窄閤併主動脈弓髮育不良患兒的二維超聲圖像,併與心血管造影,心髒CT及手術結果對比分析,總結其診斷要點.結果 除主動脈縮窄的超聲錶現外,超聲特異錶現為:胸骨上凹主動脈弓長軸切麵可見主動脈橫弓部及弓降部明顯變窄.髮育不良的範圍可自無名動脈起始後或左頸總動脈起始後;髮育不良主動脈弓的內徑/膈肌處降主動脈胸段的內徑<0.5;多普勒測定主動脈縮窄處血流速度均在正常範圍.超聲診斷均與心血管造影、心髒CT及手術結果相符.結論 超聲心動圖診斷豐動脈縮窄閤併主動脈弓髮育不良具有較高的準確性,在主動脈縮窄的診斷中.應提高對閤併主動脈弓髮育不良的認識.

Objective To study the diagnosis accuracy and features of echocardiography on aortic coarctation combined with hypoplastic aortic arch. Methods The echocardiographic characteristics of seven patients who were diagnosed as aortic coarctation combined with hypoplastic aortic arch were analyzed and compared with results of cardiac catheterization, CT scan and operation. The diagnostic features of echocardiography were summarized. Results Besides the echocardiographic characteristics of aortic coarctation,other specific echocardiographic characteristics of hypoplastic aortic arch were:distinct stenoses of transverse and decsending part of aortic arch were visualized in supra-sternal long-axis view; the range of hypoplastic part started from innominate artery beginning or left common carotid artery beginning; the ratio of diameter of hypoplastic aortic arch over that of descending aorta at diaphragm was less than 0. 5; the blood flow speed detected by Doppler at the site of aortic coarctation was in the normal range. The echocardiographic characteristics of the aortic coarctation combined with hypoplastic aortic arch were correspondent to the results of cardiac catheterization, CT scan and operation results. Conclusions There is high accuracy of echocardiography in diagnosis of aortic coarctation combined with hypoplastic aortic arch. Hypoplastic aortic arch should be paid more attention in diagnosis of aortic coarctation.
