Abstract:
PURPOSE: To analyze the angiographic findings of cerebral aneurysms and to compare them with previousdomestic and foreign reports. MATERIAL AND METHODS: Three hundred and seventeen patients underwent DSA(digitalsubtraction angiography) and the results were retrospectively, reviewed. Among 278 patients, 356 cerebralaneurysms were detected. Patient's age and sex ratio were analysed, as well as the location, size and multiplicityof the aneurysms. RESULT: The most prevalent age group was 40 to 60 years (n=211, 76%), and the male to femaleratio was 1:1.5. Aneurysms were located in the anterior (n=324, 91%) or posterior circulation(n=32, 9%). In theformer, the most common locations were the anterior communicating artery (n=98, 28%), middle cerebral artery (MCA)bifurcation(n=65, 18%) and the posterior communicating artery (n=32, 9%), while in the pasterior circulation, themost common location was the basilar tip(n=11, 3%). One hundred and eighty-eight cerebral aneurysms(53%) were 3-6mm in size, and 75(21%) were 6-10mm. The size of nine aneurysms (3%) was more than 25mm. Multiple aneurysms(n=149)occurred in 65 patients(23%) ; the most common age group was 40 to 60 (74%) and the male to female ratio was 1:4.The most common number of multiple aneurysms were two (77%) and the common locations were the posteriorcommunicating artery (21%), MCA bifurcation (18%) and anterior communicating artery (13%). CONCLUSION: Weanalyzed a large series in a single center and therefore expect that our data will be helpful for the analysis ofaneurysms in the cerebral circulation and for comparison with domestic and foreign studies.
