[Cerebral vascular accidents in anticoagulant therapy]

Thirty-three patients hospitalized as they presented with cerebral vascular lesions during anticoagulant therapy (25 intracerebral hemorrhages, 7 subdural hematoma, and one ischemia lesion). Frequency of intra-cerebral hemorrhages along with anticoagulant therapy was about 11 p. 100, this of subdural hematoma ranged from 12 to 38 p. 100. Intra-cerebral hemorrhages failed to show any peculiar topography and volume was variable. A predisposing factor thus existed in about 50 p. 100 of cases: high blood pressure or arterial aneurysm. Previous cranial traumatism was only demonstrated in 48 p. 100 patients presenting with a subdural hematoma. Prognosis as for these intracranial hemorrhages might be compared to this of hemorrhagic lesions appearing under other etiologic conditions. Ischemia lesion was secondary to a severe thrombopenia to heparin.
