摘要
目的探讨主动脉弓异常的产前超声声像图特征,以提高其产前超声诊断率。方法回顾性分析73例先天性主动脉弓异常胎儿的产前超声声像图、引产后胎儿尸检结果或新生儿超声心动图结果,并与正常胎儿产前超声图像进行对比,研究主动脉弓异常的产前超声图像特征。结果73例先天性主动脉弓异常胎儿中,主动脉弓位置异常33例,正常左位主动脉弓伴右锁骨下动脉迷走9例,主动脉弓离断5例,主动脉弓缩窄26例。本组66例经产后证实的病例资料显示主动脉弓异常产前超声诊断准确率为86.36%。最有效的扫查切面是三血管切面和三血管气管切面。结论先天性主动脉弓异常各类型均有特征性的超声表现,掌握其产前超声诊断的主要切面及产前超声声像图特征,其产前超声诊断准确率较高。但是主动脉弓严重缩窄与主动脉弓离断产前超声鉴别诊断有一定难度。
Objective To analyze the methods of prenatal sonographic diagnosis for all kinds of aortic arch anomalies and improve prenatal sonographie detection rate of aortic arch anomalies. Methods A total of 73 fetuses with congenital aortic arch anomalies were studied. The results from prenatal and postnatal ultrasound examination were compared with the health, natal ultrasound examination results. Results The 73 cases had congenital aortic arch anomalies, including 33 cases with malposition of aortic arch, 9 cases with normal left aortic arch and aberrant left subclavian artery, 5 cases with interruption of aortic arch, 26 cases with coarctation of aortic arch . The accuracy rate of prenatal sonographic diagnosis of congenital aortic arch anomalies was 86.36%. Conclusions All kinds of aortic arch anomalies have typical sonographic image. We could make accurate diagnosis with grasped typical sonographic images. But coarctation of aortic arch was poorly diagonosesed by prenatal ultrasound examination, because it was very difficult to distinguish from interrupion of aortic arch by ultrasound.
