The detection of an aberrant right subclavian artery on prenatal ultrasound should prompt careful evaluation for trisomy 21 and consideration of fetal karyotyping.
Abnormal right subclavian artery (ARSA) is the most common anomaly of the aortic arch with a rate of 0.5-1.4%. Normally, three vessels arises from the aortic arch, while four vessels arise in ARSA. ARSA leaves the distal of the aortic arch and passes behind the esophagus and trachea. It is also called the abnormal retroesophageal right subclavian artery. It is generally an asymptomatic benign finding, but it can cause esophageal compression causing dysphagia. In this article, an isolated ARSA and trisomy 21 case referred to our clinic in the second trimester of pregnancy and detected ultrasonographically is presented.

Ömeroğlu et al. (2021) conducted a case report in Aberrant right subclavian artery (ARSA) and Trisomy 21 (n=1). Aberrant right subclavian artery (ARSA) was evaluated on Fetal karyotype diagnosis. An aberrant right subclavian artery detected on second-trimester ultrasound in a 39-year-old pregnant woman was associated with a fetal diagnosis of Trisomy 21.
