Aortic arch anomalies occur due to disorders of the development of primitive double aortic arch system. In this study a patent ductus arteriosus, which had the appearance of a muscular type artery, was observed in addition to an enlarged right pulmonary artery with a diameter of 2.4 cm, causing thickening to right ventricular wall. A left common carotid artery arising from the brachiocephalic trunk was also observed. Such a complicated variation is extremely rare.
主动脉弓畸形是由于原始双主动脉弓系统发育紊乱所致。在本研究中，除了直径为2.4 cm的右肺动脉增宽导致右心室壁增厚外，还观察到一个外观呈肌型动脉的动脉导管未闭。还观察到一条发自头臂干的左颈总动脉。如此复杂的变异极为罕见。
