Table 2 Ultrasonic screening and diagnosis of 140 cases with aortic arch abnormalities in the three-vessel and tracheal view

From: Study on the views and methods of ultrasonic screening and diagnosis for abnormal aortic arch in infants

Classification Num-ber of cases the three-vessel and tracheal view
U-shaped vascular ring C-shaped vascular ring O-shaped vascular ring similar O-shaped vascular ring asymmetric “V” sign “0 l” sign
Right aortic arch with aberrant left subclavian artery 15 15 (6 + 9) 0 0 0 0 0
right aortic arch with mirror branch 6 6 (6) 0 0 0 0 0
Left aortic arch with aberrant right subclavian artery 2 0 1 (1 + 1) 0 0 0 0

  1. 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
  2. 9 9 cases were only diagnosed right aortic arch, but left subclavian artery aberration was not found
  3. 6 6 cases were only diagnosed right aortic arch, but mirror branches was not found
  4. 1 1 case were missed diagnosis of aberrant right subclavian artery
  5. 2▲ speculative diagnosis of double aortic arch with left aortic arch atresia in 2 cases
  6. 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
  7. 1 1 case of coarctation of aortic arch was incorrectly diagnosed as interruption of aortic arch
  8. 2 2 cases of interruption of aortic arch (isthmus atresia) were incorrectly diagnosed as coarctation of aorta
