Hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP) are rare but acknowledged problems of pregnancy and the postpartum period. These diseases together with thrombotic angiopathy are associated with high maternal and fetal mortality and severe long‐term morbidity. We describe four women with postpartum HUS/TTP treated with plasma exchange cryosupernatant fraction of plasma (CFP) as replacement fluid. Anuria or oliguria at the beginning of treatment and thrombocytopenia [thromb‐ (29–68) × 10 9 /L] were common features. Two of the patients developed a prolonged and more difficult clinical condition affecting the central nervous system and the liver and their platelet counts remained low despite the plasma exchange. The renal and hepatic function of all of the patients recovered fully. This small analysis lends weight to early plasma exchange with cryosupernatant as part of the treatment of postpartum HUS/TTP and suggests that persistent thrombocytopenia is a signal of more serious disease.
