Abstract

Intracerebral hemorrhages represent about 10% of the whole of vascular cerebral accidents. According to different authors, the incidence of cerebral amyloid angiopathy varies between 5-10% and up to 20-30% of all primary non-traumatic intracerebral hemorrhages. This incidence was analyzed in our environment. A retrospective study was carried out on 403 patients, 203 of them were analyzed between 1990-91 and the other 200 between 1992-3. Age, arterial tension, relapses and localization were taken as criteria for a diagnosis. For the statistical analysis, Student's T-test was used for quantitative variables, while square Chi with Yates' correction was used for qualitative variables. Ischemic cerebral accidents (90.5% of the total) are more frequent than hemorrhagic cerebral accidents, which represent 5.7%. 3.7% were not registered. Therefore, it was suspected cerebral amyloid angiopathy in 1.4% of all vascular cerebral accidents. This represents 26.1% of the total of hemorrhagic patients. Different variables from groups of hemorrhagic vascular cerebral accidents were compared to those caused by amyloid cerebral angiopathy and significant statistics were found with respect to localization in the cerebral hemispheres (p < 0.01).
