摘要
目的探讨主动脉弓离断的超声心动图特征,以提高对该疾病的认识及诊断能力。方法回顾性分析我院16例经手术、心血管造影及双源CT证实的主动脉弓离断的超声特征。结果超声心动图正确诊断11例(68.75%)均为A型;误诊5例(31.25%),其中3例IAA-A型,2例IAA-B型;主动脉弓离断超声心动图特征为:主动脉弓与降主动脉之间的连续性中断,升主动脉发育不良,肺动脉明显扩张,明显增宽肺动脉通过未闭动脉导管与降主动脉连接。结论超声心动图是诊断主动脉弓离断的首选方法,在超声检查中发现肺动脉明显扩张,升主动脉发育不良,并且肺动脉高压与心内畸形不匹配者,应警惕主动脉弓离断可能,仔细探查主动脉弓,若主动脉及分支显示不清,联合MRI、CT检查可提高诊断率。
Objective To investigate the characteristics of echocardiography of interruption of aortic arch in order to improve theunderstanding and diagnosis of the disease.Methods The sonographic features of 16 patients with interruption of aortic archconfirmed by surgery,angiocardiography and dual -source CT were analyzed retrospectively.Results Echocardiography correctlydiagnosed 11 cases （68.75%）were type A;5 cases were misdiagnosed （31.25%）,3 cases of IAA-A type,2 cases of IAA-B type;Theinterruption of aortic arch echocardiographic features are：continuous interruption between the aortic arch and the descending aorta,ascending aorta dysplasia,pulmonary artery expansion,significantly widening the pulmonary artery through the patent ductus arterialconnection with the descending aorta.Conclusion Echocardiography is the first choice for the diagnosis of interruption of aortic arch.In the ultrasound examination,the pulmonary artery is obviously dilated,the ascending aorta is poorly developed,and the pulmonaryhypertension and intracardiac malformation are not matched.It should be alert to the possibility of interruption of aortic arch.Carefullyexplore the aortic arch.The aorta and branches are unclear,and combined MRI and CT examinations can improve the diagnosis rate.
