Placenta accreta on non-scarred uterus: About a case

Abstract

Placenta accreta is an abnormally adherent placenta (abnormal adhesion of the placenta to the myometrium), due to the localized or diffuse absence of the decidua basalis. Its incidence increases with increasing cesarean section rates. Placenta accreta in a non-scarred uterus is very rare but remains possible due to other risk factors which are age, smoking, placenta preavia and finally invasive endouterine procedures. Among its consequences, we first note the hemorrhage of delivery which can be associated with significant maternal morbidity and mortality, uterine rupture and also the invasion of adjacent organs by the placental trophoblast. We report an interesting case of placenta accreta on a non-scarred uterus discovered during a planned cesarean section for placenta previa. This is a 41-year-old patient with no history of scarred uterus, 5th procedure, 3rd parity, with history of spontaneous miscarriage cured at 2 months, pregnant at 39 weeks, unmonitored pregnancy, admitted to the maternity emergency room for two days before for delivery method where the parturient benefited from a clinical examination and an obstetric ultrasound showing a completely covering anterior placenta, amniotic fluid of normal quantity and an estimate of the fetal weight at 2800g, then scheduled for a cesarean section. The diagnosis of placenta accreta is made during cesarean section. We opted for radical treatment. Placenta accreta is a pathology at risk of serious hemorrhagic complications during pregnancy and the postpartum period. This should encourage us to systematically search for ultrasound criteria for placenta accreta. The ultrasound report, in these patients, must explicitly mention this. Adequate care in the presence of a multidisciplinary team makes it possible to limit the mortality and morbidity associated with this pathology.
