Unexpected Dramatic Evolution of Placenta Increta: Case Report and Literature Review

Abstract

Placental morbid adherence is a known risk factor for postpartum hemorrhage. The incidence of abnormal placental attachment has been increasing over the past few decades, mainly due to rising rates of cesarean deliveries, advanced maternal age, and the use of assisted reproductive technologies. Cesarean section is a significant risk factor for placenta increta, as it disrupts the normal architecture of the uterine wall, making it more difficult for the placenta to detach after delivery. We present the case of a woman who underwent a cesarean section at 28 weeks due to anterior placenta previa, accompanied by hemorrhage and rupture of membranes. Following the delivery, she experienced normal postoperative bleeding and was discharged home after five days. However, six weeks later, she presented with heavy bleeding, leading to the decision to perform a total hysterectomy. The levels of HCG were found to be low. The pathological examination of the specimens confirmed a diagnosis of placenta increta, as it revealed notable placental proliferation, necrotic villi, and placental invasion near the uterine serosa. Notably, we did not find any similar cases documented in the literature. Patients experiencing prolonged vaginal bleeding after childbirth and diagnosed with placenta accreta should be closely monitored through ultrasound examinations; abnormal proliferation of the placenta can occur, and prompt detection is crucial for appropriate management.

Assessment of Serum Survivin in Women with Placenta Previa and Accreta Spectrum.

“…We also observed a signi cant age difference among the participants, suggesting that older mothers are at a higher risk of developing PAS, potentially because of age-related uterine changes. The association between multiple cesarean sections increased PAS risk underscores the need for cautious obstetric management in such cases [15,16]. Despite the small sample size, trends indicated more obstetric/perinatal complications in the PAS and placenta previa groups than in the controls, highlighting the need for careful management [17].…”
