The case for making the first-trimester anatomical survey a standard of care post Dobbs

Currently, 11- to 14-week-detailed anatomic surveys are generally reserved for at-risk populations because of the lower incidence of major fetal anomalies in low-risk populations. Until recently, such standard reflects, in part, the fact that pregnant persons retain the option of abortion even if the initial anatomy scan was in the second trimester of pregnancy. However, on June 24, 2022, the US Supreme Court overturned Roe, and many states subsequently lowered the gestational age at which abortions can legally be performed. Here, we argue for a reconsideration of limitations on first-trimester scans to preserve pregnant persons' reproductive options, particularly in those states that have imposed laws limiting access to abortion. Moreover, we acknowledge and discuss some of the challenges that will be associated with this approach.
