Supplementary Material for: The challenging management of acute thrombotic microangiopathy in pregnancy

Thrombotic microangiopathy is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ injury. Pregnancy-associated thrombotic microangiopathy is a severe disorder with high risk of maternal mortality and poor fetal outcomes. Preeclampsia (PE)/eclampsia and hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome are the most common causes and hemolytic uremic syndrome (HUS) or thrombotic thrombocytopenic purpura (TTP) are rare causes. Due to overlapping clinical findings, the differential diagnosis is challenging, and should be managed by a multidisciplinary team. We present a case of a 38-year-old woman at 40 weeks of second gestation, admitted with thrombotic microangiopathy being the final diagnosis not immediately clear.
