摘　　要：目的探讨复杂主动脉弓畸形的超声表现及误、漏诊原因。方法回顾性分析15例少见主动脉弓畸形的超声图像,包括主动脉弓离断9例、双主动脉弓1例、右位主动脉弓伴左侧动脉导管未闭3例、永存第五对主动脉弓2例。所有病例均经CT检查及术中发现证实。结果15例患者的超声诊断中,主动脉弓离断1例漏诊(1/9),双主动脉弓1例漏诊(1/1),右位主动脉弓伴左侧动脉导管未闭1例误诊(1/3),永存第五对主动脉弓1例误诊(1/2)、1例漏诊(1/2),其余术前超声均获得正确诊断。结论超声心动图对主动脉弓离断能做出较准确诊断,但对双主动脉弓、右位主动脉弓合并左侧动脉导管未闭及永存第五对主动脉弓等几类畸形易误诊或漏诊,增强认识并仔细扫查有望提高超声检出率。Objective To evaluate ultrasonic manifestations of several types of complex aortic arch malformation and the causes of misdiagnosis and missed diagnosis.Methods The echocardiograms of 15 patients with rare types of complex aortic arch malformation including interruption of aortic arch（IAA,n=9）,double aortic arch（DAA,n=1）,right aortic arch combined with left patent ductus arteriosus（PDA,n=3） and persistent fifth aortic arch（PFAA,n=2） confirmed with CT and operation were analyzed retrospectively.Results Echocardiography missed 1 case of IAA,1 case of DAA and 1 case of PFAA.One case of right aortic arch combined with left PDA and 1 case of PFAA were misdiagnosed with echocardiography.Conclusion Missed diagnosis or misdiagnosis are prone to take place in PFAA,DAA,and right aortic arch with left PDA than in IAA with echocardiography.Careful echocardiographic scanning with enhancement diagnostic consciousness is helpful to elevate the detection rate of complex aortic arch malformations.
