[Hematological changes and cerebrovascular disorders].

Stroke is due to abnormalities in the vascular wall, heart disease or hematological abnormalities. This last cause has a low causal rate in stroke but despite this its importance is self evident given that there still exists a number of stroke patients where etiology cannot be established. An exhaustive check was carried out on the different hematological phenomena which may play a part in the etiology of ischaemic or hemorrhagic strokes. We analyzed abnormalities in the red series, white series and blood cells; coagulapathies; discrasias of the plasmic cells and antiphospholipid antibodies. For each of the hematological entities, conceptual criteria, their role in brain hemorrhage or ischaemia, and therapeutic measures were established.
