Predictive value of aberrant right subclavian artery for fetal chromosome aneuploidy in women of advanced maternal age

open access: yesBMC Pregnancy and Childbirth, 2021
Background In the entire population, an aberrant right subclavian artery (ARSA) is closely associated with chromosomal abnormalities. ARSA with additional ultrasonic findings would increase risk of chromosomal abnormalities. The risk of fetal chromosomal
