Placental abruption or abruptio placentae is premature separation of the placenta from the uterine wall prior to delivery.
Before giving birth, placental abruption happens when the placenta separates from the uterus' inner wall. A placental abruption can deprive the infant of oxygen and nourishment while also leaving the mother with severe bleeding.
When the vascular structures sustaining the placenta are compromised, placental abruption results. In other words, the vascular networks that connect the placenta's maternal side to the uterine lining are severed. The fetus receives oxygen and nutrients from these vascular systems. When the vascular structures are damaged due to hypertension, substance abuse, or disorders that cause the uterus to stretch, the vascular network may become disrupted. The placenta is less elastic than the uterus despite being a muscle like the uterus. As a result, when the uterine tissue suddenly extends, the placenta stays stable while the vascular system that connects the uterine wall to the placenta tears.
