It results from abnormal intravascular platelet aggregation that leads to transient ischemia in various organs, including the central nervous system, kidneys and placenta. Plasma exchange is the most widely accepted method of treatment for this condition. Delayed diagnosis is the main reason for morbidity and mortality, and results from difficulty in differentiating thrombotic microangiopathy from other obstetric emergencies. We report two cases of thrombotic microangiopathy that occurred antepartum and postpartum, respectively. The first patient was a 33-year-old woman who had two previous episodes of intrauterine fetal death in the 13th and 28th weeks of gestation, respectively. She received early plasma exchange at the 23rd week of gestation during this pregnancy and the fetus was delivered uneventfully. The second patient was a 28-year-old woman with progressive thrombocytopenia, anemia and deterioration of renal and liver function postpartum. She received early plasma exchange and it markedly improved her thrombocytopenia without sequelae. In conclusion, early diagnosis and early initiation of plasmapheresis may improve both maternal and fetal prognosis in thrombotic microangiopathy.[SDGs]SDG3acetylsalicylic acid; heparin; lactate dehydrogenase; prednisolone; adult; anemia; article; brain ischemia; case report; clinical feature; controlled study; delivery; deterioration; differential diagnosis; disease association; disease course; early diagnosis; female; fetus death; fetus mortality; gestation period; human; kidney function; kidney ischemia; liver function; maternal morbidity; maternal mortality; perinatal morbidity; placenta perfusion; plasmapheresis; pregnancy; pregnancy complication; prenatal period; prognosis; puerperium; thrombocyte aggregation; thrombocyte count; thrombotic thrombocytopenic purpura; treatment outcome; Adult; Female; Hemolytic-Uremic Syndrome; Humans; Plasma Exchange; Pregnancy; Pregnancy Complications, Hematologicjournal article126328202-s2.0-0036983875
