[Role of ischemic cerebral infarction in the development of lethal outcomes in ruptured intracranial arterial aneurysm].
Analysis of 320 autopsy cases of death after the rupture of brain arterial aneurysms (AA) without a surgical treatment is performed. The frequency of ischemic infarction among these cases was 15.3% and in 11.2% the infarction was an immediate cause of death. The lethal outcome due to the infarction occurred at the end of the 1st and during the 2nd week with a maximum at 9-12 days. Ischemic infarction as a cause of death usually had a wide zone of spread involving 2 and more brain lobes. The thrombosis of the big brain artery was a cause of ischemic complications in 19.4% of cases. Morphological alterations of the basis cerebri in such cases consisted of changes in the intima, elastic membrane, medial layer and adventitia resulting in the lumen narrowing.
