- △accurate diagnosis ▲speculative diagnosis ☆missed diagnosis ★incorrect diagnosis ▼This view does not show a normal image of the aortic arch, but this view alone cannot make a accurate diagnosis
- 9☆ 9 cases were only diagnosed right aortic arch, but left subclavian artery aberration was not found
- 6☆ 6 cases were only diagnosed right aortic arch, but mirror branches was not found
- 1☆ 1 case were missed diagnosis of aberrant right subclavian artery
- 2▲ speculative diagnosis of double aortic arch with left aortic arch atresia in 2 cases
- 1▼ dysplasia of aortic arch was found in 1 case, and the blood flow of ductus arteriosus shunted from pulmonary artery to aortic arch, but definite diagnosis of atresia of aortic arch could not be made
- 1★ 1 case of coarctation of aortic arch was incorrectly diagnosed as interruption of aortic arch
- 2★ 2 cases of interruption of aortic arch (isthmus atresia) were incorrectly diagnosed as coarctation of aorta
