The thrombotic microangiopathies are a complex group of disorders that typically present with a schistocytic hemolytic anemia and associated thrombocytopenia with ensuing microvascular occlusion leading to tissue ischemia
and end organ damage. Central nervous system, renal, gastrointestinal and cardiac microcirculations are frequent
targets. Signs and symptoms related to organ dysfunction may evolve over weeks to months and may not be
present simultaneously. Lactic dehydrogenase enzyme elevation due to microvascular ischemia is frequently
disproportionate to elevation of bilirubin or reticulocyte count. The major thrombotic microangiopathies include
Thrombotic thrombocytopenic purpura, Disseminated intravascular coagulation/sepsis, and Hemolytic Uremic
