Early ultrasound assessment in women with a prior cesarean delivery shows promise for predicting cesarean scar pregnancy (CSP). The study links markers such as a gestational sac low in the anterior uterine wall near the scar and a thin myometrial layer to higher CSP risk, underscoring the value of vigilant early scans (6–8 weeks) to enable timely management and potentially reduce maternal-fetal morbidity. The findings suggest integrating targeted early surveillance into practice, while acknowledging the need for larger, multicenter research to validate predictive criteria and formalize guidelines.

The study, published in Ultrasound in Obstetrics & Gynecology, analyzed data from 150 women with a history of cesarean delivery who had early pregnancy ultrasounds between 6 and 8 weeks.
A key finding was that a gestational sac located low in the anterior uterine wall near the prior cesarean scar correlated with an increased risk of CSP.
Another associated marker was a thin myometrial layer overlying the gestational sac, observed in the CSP-related cases.
The authors advocate for vigilant early ultrasound surveillance in women with prior cesarean deliveries to assess sac location and myometrial thickness.
Early detection is framed as enabling timely interventions that could reduce maternal and fetal morbidity linked to CSP.
The study calls for larger, multicenter trials to validate these markers, refine predictive criteria, and develop standardized clinical guidelines.
