摘要
目的观察儿童永存第五主动脉弓(PFAA)的超声心动图表现。方法观察5例经CT血管造影(CTA)及手术确诊PFAA患儿的超声心动图表现,记录相关临床资料。结果5例PFAA,包括1例Weinberg A型及4例Weinberg B型。超声心动图左心室流出道切面均见第五主动脉弓自升主动脉远端发出,胸骨上窝长轴切面见2个并存且平行走行的主动脉弓,4例Weinberg A型上方为第四主动脉弓、下方为第五主动脉弓,均与降主动脉相连;1例Weinberg B型上方第四主动脉弓离断,仅见下方的第五主动脉弓与降主动脉相连。5例中,4例接受PFAA矫治术,术后随访主动脉弓血流均通畅;1例因第五主动脉弓血流通畅而未接受PFAA矫治术。结论不同类型PFAA超声心动图表现存在差异,联合观察左心室流出道切面和胸骨上窝长轴切面有助于提高PFAA检出率。
Objective To observe the echocardiographic manifestations persistent fifth aortic arch(PFAA)in children.Methods The echocardiographic manifestations of 5 children with PFAA confirmed by CT angiography(CTA)and operation were observed,and related clinical data were followed up.Results There were 1 case of Weinberg type A and 4 cases of Weinberg type B PFAA.Echocardiogram of the left ventricular outflow tract plane showed that the fifth aortic arch arose from the distal ascending aorta,and the long axial plane of the suprasternal view showed two coexisting and parallel aortic arches.For Weinberg type A PFAA,the fourth aortic arch existed above and the fifth aortic arch below,both connected with the descending aorta.For Weinberg type B,the upper arch of the fourth aorta was interrupted,and only the lower arch of the fifth aorta connected to the descending aorta.In time PFAA correction was performed in 4 children,and the aortic arch blood flow was found unobstructed during postoperative follow-up.One child did not underwent PFAA correction due to smooth fifth aortic arch blood flow.Conclusion Different types of PFAA had various echocardiographic manifestations.Combining observation of left ventricular outflow tract and the long axis plane of the suprasternal was helpful to improving detecting rate of PFAA.
