Recurrent severe placenta increta at 8 weeks of gestation in a twin pregnancy following uterus-conserving surgery for prior placenta accreta spectrum disorder

Abstract

Objective: We describe herein our experience of employing a hysterectomy and prophylactic internal iliac artery balloon occlusion (IIABO) strategy for the management of recurrent severe placenta increta at 8 weeks in a twin pregnancy following uterus-conserving surgery for prior placenta accreta spectrum (PAS) disorder. Case report: A 40-year-old woman with a history of uterus-conserving surgery for PAS disorder underwent transvaginal ultrasound evaluation at 8 weeks of pregnancy, which showed a dichorionic/diamniotic pregnancy with viable embryos of a crown-rump length of 1.65 cm and 2.03 cm, respectively. Many irregularly-shaped grade 3+ lacunae were observed, and color Doppler imaging revealed diffuse intraplacental and perihypervascularity. A total abdominal hysterectomy was performed at 10 weeks, with an estimated blood loss of 1275 mL. Placenta increta was confirmed by histopathologic examination. Conclusion: The high rate of recurrence of PAS disorder in a subsequent pregnancy should be discussed following an antenatal diagnosis of PAS disorder with patients who may be considering uterine conservation in order to retain the option of a future pregnancy.
