Acute trophoblastic pulmonary embolism during conservative treatment of placenta accreta: Case report and review of literature

Abstract

Background: Placenta accreta is a rare obstetric condition but can lead to life-threatening complications that was mainly diagnosed in the third trimester. We present a case of acute trophoblastic pulmonary embolism (PE) during conservative treatment of placenta accreta. Case presentation: A 24-year-old patient who delivered vaginally at 40+4 weeks gestation. The placenta was retained despite the use of oxytocics and attempts of manual removal. Conservative management including uterine arteria embolism, hysteroscopic resection and mifepristone was used but failed and finally the patient died from acute trophoblastic PE and allergic shock when infusing povidone-iodine into her uterine cavity. Conclusion: Although conservative treatment of placenta accreta can retain reproductive potential and trophoblastic PE is rare, clinicians should consider hysterectomy when conservative treatment failed and infusion of povidone-iodine or other liquid into the cavity should be prohibited.
