Management of postpartum pulmonary embolism combined with retained placenta accreta: A case report.

rationaleRetained placenta accreta is an increasing obstetric problem in recent years, and pulmonary embolism (PE) during pregnancy and the postpartum period is a vital condition, but lack of standard therapy guidelines. This report describes a case of postpartum PE combined with retained placenta accreta. PATIENT CONCERNS: A 27-year-old woman presenting with fever and dyspnea after delivery was admitted to our hospital with retained placenta accreta. DIAGNOSES: The patient was diagnosed with the infection, postpartum PE, and residual placenta.

interventionsThe antibiotics and low molecular weight heparin were initially started to cure the infection and control PE. Mifepristone was then used to promote the necrosis of residual placenta while long-term use of warfarin was served as continuous anticoagulant therapy. Hysteroscopic resection of retained placenta was not performed until thrombi had been almost disappeared after more than 2 months of anticoagulation therapy. OUTCOMES: The patient's menstruation returned to normal within several weeks after hysteroscopic resection and she completely recovered from PE after 3 months of anticoagulant therapy. LESSONS: Treatment of retained placenta accreta can be postponed when encountering complicated cases, such as postpartum PE. PE in perinatal stage can be managed referring to nonmaternal PE.
