ABSTRACT
Purpose To explore the value of echocardiography and CT angiography (CTA) in diagnosing persistent fifth aortic arch (PFAA). Materials and Methods Eight children clearly diagnosed as PFAA in Children's Hospital of Chongqing Medical University from Jan. 2012 to Dec. 2016 were retrospectively analyzed. Clinical data were collected, and the features of echocardiography and CTA images were compared and summarized, which were then compared with the surgical results. Results ①Eight cases received CTA, CTA could clearly reveal anatomical spatial structure of PFAA such as its origin and courses. ②Four cases were fully recovered and discharged from hospital after receiving extracorporeal circulation PFAA sternotomy under general anesthesia.③According to Weinberg classification, 2 cases were classified as type A, 5 cases type B, and 1 case type C. ④5 cases of PFAA were firstly diagnosed via echocardiography (1 case of type A and 4 cases of type B), the diagnose accordance rate with the results of CTA and/or surgery was Conclusion Echocardiography and CTA can effectively diagnose PFAA, help early detection and improve prognosis.
