Intracranial aneurysms in geriatric patients: angiographic features and angioautotomographic analyses.
The angiographic investigation of intracranial aneurysms in geriatric patients was made by conventional cerebral angiography and angioautomography. Analyses were based on 49 aneurysms in 38 patients aged over 60 who had 24 (49.0%) large aneurysms of maximum diameter over 100 mm. This contrasted strongly with the aneurysms of patients aged under 60, only 14.4% of which were large. Cerebral angioautotomography had a particular diagnostic value for such large aneurysms, revealing not only the stalks and the whole shapes of aneurysms, but also the normal parent arteries which were hidden on conventional cerebral angiography.
