Abstract:

Objective: To investigate the application of magnetic resonance imaging (MRI) in the diagnosis and treatment of uterine incarceration during pregnancy.Methods: Four cases of uterine incarceration during pregnancy treated in the Obstetrics Department of Peking University Third Hospital from 2010 to 2020 were retrospectively analyzed. MRI and ultrasound were used in the diagnosis of these cases, and the application value of MRI in preoperative evaluation were evaluated. Results: 2 cases with placenta previa, and 2 cases with abnormal cervix and lower uterine segment, were found by the primary ultrasound. The definite diagnosis of 4 cases was made by MRI examination. The pregnancy outcomes were included 1 case with vaginal delivery at term after reset in the second trimester, 1 case with cesarean section at mid-trimester because of placenta increta, and 2 cases with deliberated cesarean section at third-trimester. Conclusions: MRI can make a definite diagnosis for those suspected cases of uterine incarceration during pregnancy, as a reference for surgical plan. For ultrasound the suspected cases of uterine incarceration, the definite diagnosis by MRI will improve the outcomes of mother and child.
