Association of Intrauterine Device Malposition With Previous Cesarean Delivery and Related Uterine Anatomical Changes.

Objectives: We sought to determine the association between intrauterine device (IUD) malposition and previous cesarean delivery (CD) and related uterine anatomical changes.

Methods: A retrospective cohort of all persons with an IUD presenting for two- and three-dimensional pelvic ultrasonography over 2 years, for any gynecologic indication, was compiled. IUD malposition was defined as IUD partially or completely positioned outside the endometrial cavity.

Transfusion Medicine in a Multidisciplinary Approach to Morbidly Adherent Placenta: Preparing for and Preventing the Worst.

The increasing incidence of placenta accreta has paralleled the rise in its greatest risk factor: cesarean delivery. In placenta accreta, the abnormal invasion of the chorionic villi into the myometrium prevents separation of the placenta at delivery, and the myometrium is unable to contract to prevent hemorrhage. Spontaneous uterine rupture and hemoperitoneum may also occur in the setting of placenta percreta.
