Placenta Accreta Spectrum in Unscarred Uterus: A Case Report in a Tertiary Facility

Background: Placenta accreta spectrum (PAS) is a broad term that includes placenta accreta, placenta increta, and placenta percreta. The major risk factor is a scarred uterus commonly as a result of prior cesarean delivery, myomectomy, or uterine instrumentation. We report a case of placenta increta in the absence of identifiable risk factors. Case presentation: A 22-year-old, para 2 living 2, presented with postpartum hemorrhage due to retained placenta post vaginal delivery at a gestational age of 38 weeks and 4 days, manual removal of placenta was attempted general anesthesia without success; necessitating explorative laparotomy where the placenta was found deeply invading into the myometrium. Intractable bleeding necessitated supracervical hysterectomy. Histopathological results later revealed placenta increta. Conclusion: PAS in an unscarred uterus in the absence of other identifiable risk factors is quite uncommon; however, carries high maternal morbidity and mortality. This case serves as an eye opener on the need to evaluate for radiological features of PAS during antenatal visits even in low-risk group.
