Abstract

TA-TMA is a serious complication of hematopoietic stem cell transplantation, presenting as microangiopathic hemolytic anemia with severe renal injury and mortality as high as 60%. Diagnosis and treatment of TA-TMA is very challenging after HSCT because anemia, thrombocytopenia, hypertension, and renal impairment are multifactorial, leading to delayed recognition and management of this complication. We report a successful outcome following early intervention for hyperacute TA-TMA after allogeneic HSCT.
