Aberrant right subclavian artery: will it need surgery?

The article discusses the prevalence and management of aberrant right subclavian artery (ARSA) in infants. ARSA is a common finding, occurring in about 1.5% of karyotypically normal fetuses. While it is often detected prenatally, the need for surgical intervention is rare, especially if there are no other associated genetic abnormalities or symptoms. The study found that out of 528 prenatally diagnosed cases, only seven underwent surgery. The most common symptoms associated with ARSA were noisy breathing/stridor, dysphagia, and recurrent chest infections. Overall, the study suggests that expectant parents can be reassured that postnatal complications are unlikely if their fetus is diagnosed with ARSA and has an otherwise normal heart.
