| 目的 探讨主动脉弓中断的超声探测方法及其超声特征表现。方法 8例主动脉弓中断患者,每例均于剑突下、心尖、胸骨旁及胸骨上窝等透声窗全面扫查,按顺序分段诊断分析。结果 超声心动图确诊8例主动脉弓中断,准确率100%。其特征性超声表现为胸骨上窝切面主动脉弓降部显示困难,弓部曲线多较直、较长;弓部与降主动脉失去明显联系;弓部为盲端,血流中断,降主动脉与肺动脉相连,常合并室间隔缺损,动脉导管未闭,均有重度肺动脉高压等。结论 超声可明确诊断主动脉弓离断;常规胸骨上窝探查,注意探测方法,可提高检出率和诊断率。 |

| Objective To evaluate the echocardiographic characteristics of interrupted aortic arch (IAA). Methods Eight patients suspected of IAA were carefully and overallly scaned with echocardiography from subcostal, apex, paresternal and suprasternal windows, and the images were analysed segmentally for diagnosis. Results Eight cases of IAA were exactly diagnosed by echocardiography (8/8,100%). Characteristic echocardiographic findings of IAA were diaplayed in these patients. Aortic arch was difficult to show in suprasternal windows, and aortic arch was usually long, straight, and interrupted, the blood flow broke down, and the descending aorta connected with pulmonary artery through patent ductus arteriosus, usually accompanied with ventricular septal defect and pulmonary hypertension. Conclusion Suprasternal view is helpful to the echocardiographic diagnosis of IAA. |
