Difference Between Mean Gestational Sac Diameter and Crown-rump Length as a Marker of First-trimester Pregnancy Outcome in Patients With Recurrent Spontaneous Abortion
In Brief
An observational study evaluating ultrasonic testing for Recurrent Spontaneous Abortion. Completed, enrolled 256 participants across 1 site.
Detailed Summary
Objective: To determine the effect and predictive value of the difference between the mean gestational diameter (mGSD) sac and crown-rump length (CRL) of the first trimester on the pregnancy outcomes of patients with recurrent spontaneous abortion (RSA).Methods: This is a retrospective cohort study. In total, 256 pregnant women at 6-10 weeks of gestation and with RSA who visited our hospital from January 2020 to March 2023 were included in the study. They were divided into the following three groups based on the difference between the mGSD and CRL (mGSD-CRL): Group A: mGSD-CRL ≥ 10mm, 41 cases; Group B: 10mm \< mGSD-CRL ≤ 15mm, 109 cases; and Group C: mGSD-CRL \> 15mm, 106 cases.
