Abstract

Objective: To approach the diagnostic accuracy of echocardiography, multi-slice spiral CT angiography(MSCTA) of persistent fifth aortic arch(PFAA) and modify the description of PFAA by developing a new classification system． Methods: Echocardiogram and MSCTA of three selected PFAA cases were retrospectively analyzed with the current classification and the new classification. Results: One case of type A1(type Weinberg-A), one case of type A2(type Weinberg-B) and one case of type A3(abnormal origin of brachiocephalic artery) could be visualized clearly and directly by MSCTA. Morphology of PFAA and its flow disturbance could be seen on echocardiogram in cases of type A1 and type A2, although the other case of type A3 was miss diagnosed due to ignoring the suprasternal views. Conclusions: The anatomical and hemodynamic characteristics of PFAA can be accurately diagnosed by echocardiography combined with MSCTA. This new classification includes all of the potential PFAA and facilitates their analysis.
