Abstract
Background and purpose: Placenta accreta spectrum (PAS) is an abnormal placental adherence or invasion of the myometrium or extrauterine structures. Its prevalence increases proportionally to the number of cesarean sections. The aim of this retrospective cohort study was to evaluate maternal and neonatal outcomes in patients with placenta previa and placenta accreta.
Methods: A retrospective analysis of patients with placental attachment disorders was performed in the Training and Research Hospital. Data collection was performed using the medical records of patients with placenta accreta and previa, analyzing maternal and neonatal outcome.
Results: Five cases of placenta previa accreta were identified in the last 3 years out of a total of 5,235 deliveries. The mean maternal age was 35.3 years and the gestational age ranged from 27 to 39 weeks. Five cases were diagnosed prenatally by ultrasonography or MRI. Three had hysterectomies during the intrapartum period, and two cases were treated conservatively. Bilateral hypogastric artery ligation was performed in three cases.
Conclusion: Placenta accreta spectrum (PAS) is an abnormal placental adherence or invasion of the myometrium or extrauterine structures. Prenatal diagnosis of PAS is essential to plan delivery in a competent tertiary care center.
