摘要Post-partum hemolytic uremic syndrome (PHUS) is a severe thrombotic microangiopathy clinically characterized by hemolytic anemia,renal dysfunction,and low platelets after birth with rapid progression and poor prognosis.Here,we reported a rare case of severe preeclampsia diagnosed as hemolytic uremic syndrome after birth.The patient was diagnosed with PHUS and underwent intermittent plasma exchange with supportive treatment including glucocorticoid injections and transfusion of suspended red blood cells.After these treatments,the patient experienced no apparent remission and chronic renal dysfunction occurred on her.PHUS is a severe emergency with acute onset,rapid progress,and poor prognosis.Early detection,diagnosis,and treatment can significantly improve the prognosis.
