title: Microangiopathic hemolytic anemia in renal allotransplantation. Repart of a successfully treated case and review of the literature.
abstract: The development of microangiopathic hemolytic anemia after renal transplantation in a 17 year old white boy is reported, and the literature is reviewed. In this patient microangiopathic hemolytic anemia developed 6 weeks after renal transplantation during a second episode of rejection. Light, fluorescence and electron microscopy demonstrated the renal vascular lesion associated with this syndrome. In contrast to the other four previously reported cases of microangiopathic hemolytic anemia associated with renal allotransplantation, this patient had complete resolution of the microangiopathic hemolytic anemia with heparin therapy and improved allograft function, presumably with diminution of the vascular lesion. He survived a complicated early period after renal transplantation and has shown no recurrence of microangiopathic hemolytic anemia in the 18 months since transplantation. Special red blood cell and fibrinogen studies are discussed.
