Abstract
- Authors studied the hemodynamical and angionatomical structures of the anterior cerebral artery complex in one hundred normal adult angiograms and thirty angiograms demonstrating anterior communicating artery aneurysms, which were admitted to the Department of Neurosurgery, Seoul National University Hospital in recent three years. The results are as following : 1. Observation of anterior cerebral artery complex in 100 normal adult angiogram show : Symmetrical anterior cerebral artery complex ; 77%, Asymmetrical ; 16%, Hypoplastic or aplastic : 7%. 2. Observation of anterior cerebral artery complex in 30 anterior communicating artery aneurysm angiogram shows : Symmetrical ; 40%, Asymmetrical ; 23%, Hypoplastic or aplastic : 37%. 3. Type classification of anterior cerebral artery complex in anterior communicating artery aneurysms show : Type I; 40, Type II; 13%, Type III; 47%. 4. In normal adult angiograms with cross compression test visualized portion of contralateral cerebral blood vessels is as following : A1; 7%, M1; 4%, M2; 9%, M3 or M4 ; 80%.
