[Incarceration of the Gravid Uterus in the Second Trimester - Diagnostics, Successful Therapy and Review of Literature].

A rare complication in obstetrics is the incarceration of the gravid uterus. If the uterus remains retroverted, the fundus persists in the pelvic cavity. Due to growth, the familiar anatomy of the uterus changes and undetected incarceration can lead to a serious maternal morbidity. Early treatment can enable a normal prolongation of pregnancy. In our case, we report a first gravida with initial diagnosis of a posterior sacculation of the uterus in the 21st week of pregnancy. After confirmed diagnosis by MRI, the reduction of the uterus by vaginal digital lifting of the uterus and simultaneous rectoscopic CO2 filling was successful. A spontaneous delivery without complications after rupture of membranes followed in the 35th week of pregnancy. Thieme. All rights reserved.
