- Abstract
Purpose: To determine the frequency of aberrant right subclavian artery among the low-risk fetuses and to evaluate its association with chromosomal abnormalities and the other congenital heart diseases. Methods: A total of 4,125 consecutive fetuses were examined for the presence of aberrant right subclavian artery that arises from the descending aorta distal to the left subclavian artery. Results: Aberrant right subclavian artery was detected in 17 cases (0.4%). In nine cases it was an isolated finding. In four cases (23.5%) it was accompanied by another cardiac defect. Extracardiac malformations were present in three fetuses (17.6%). Among the 13 cases of aberrant right subclavian artery in which the karyotypes were known, one case presented with Down syndrome (7.6%). In this fetus, aberrant right subclavian artery was the only finding. Conclusion: These findings suggest that aberrant right subclavian may be an isolated finding in trisomy 21. The visualization of subclavian artery should be a part of fetal echocardiographic examination as it may be a valuable marker for Down syndrome.
