Microangiopatia trombótica, não classificada em outra parte.
CategoryDefinition
Thrombotic microangiopathies are microvascular occlusive disorders characterised by systemic or intrarenal aggregation of platelets, thrombocytopenia, and mechanical injury to erythrocytes. Thrombotic thrombocytopenic purpura (TTP) and haemolytic–uremic syndrome (HUS) represent a spectrum of thrombotic microangiopathies. In TTP, systemic microvascular aggregation of platelets causes ischemia in the brain and other organs. In HUS, platelet–fibrin thrombi predominantly occlude the renal circulation.
