Abnormalities in the development of the aortic arch system may yield anomalies either of the definitive aortic arch and its branches or of pulmonary arterial origin. Anomalies of the aortic arch and its branches may cause compression of the trachea and esophagus or simply yield anatomic patterns which vary from normal without causing specific symptoms. Anomalies of pulmonary arterial origin usually take the form of origin of one or both pulmonary arteries either from the aorta or the innominate artery. The various anomalies are related to loss of specific segments of the primitive aortic arch system.
主动脉弓系统发育异常可能导致最终主动脉弓及其分支或肺动脉起源出现异常。主动脉弓及其分支的异常可能会压迫气管和食管，或者仅仅产生与正常情况不同的解剖结构模式而不引起特定症状。肺动脉起源异常通常表现为一根或两根肺动脉起源于主动脉或无名动脉。各种异常与原始主动脉弓系统特定节段的缺失有关。
