Definition
The premature placental detachment consists in the loss of adherence of the same with respect to the inner wall of the uterus in which it is implanted.
The severity of the symptoms depends on the degree of detachment - which can be acute or chronic, a few millimeters or complete - and the loss of maternal blood. In any case, premature placental detachment is still an obstetric emergency, especially if it occurs at an advanced stage of gestation.
The premature detachment of the placenta is almost always due to pathological conditions; it can occur in case of pre-eclampsia, placental ischemia, intrauterine infections (eg corioamnionitis), abdominal trauma, maternal thrombotic disorders and premature rupture of membranes. Other possible risk factors include hypertension (induced by pregnancy or chronic), heart disease, vascular disease, advanced maternal age, smoking and drug abuse (cocaine). Multiple pregnancies are the most affected
The premature detachment of the placenta is manifested by vaginal bleeding (with possible hemorrhagic shock and / or disseminated intravascular coagulation), intense and continuous abdominal pain, tense and irritable uterus on palpation, and general malaise.
The premature detachment of the placenta must be differentiated from the placenta previa.
