Background : Subarachnoid hemorrhage has a high mortality and morbidity rates, and the cerebral aneurysm is the most common cause. The
location of the ruptured cerebral aneurysm is diagnosed by cerebral angiogram and by computed tomography (CT) pattern of the subarachnoid
hemorrhage.
Objective : To find the incidence of CT pattern of each cerebral aneurysm and the correlation between CT pattern of subarachnoid hemorrhage and each location of cerebral aneurysm.
Materials and Methods : The 126 patients with ruptured cerebral aneurysm were included in the present study. The information of the patients and CT were recorded and analyzed.
Results : There were 49 male and 77 female patients. The highest location of cerebral aneurysm is anterior communicating aneurysm (59 patients, 47.6%). There were correlations between A region and anterior cerebral and anterior communicating aneurysm, and left D legion and the other location aneurysm. There were correlations between intracerebral hemorrhage and anterior communication, posterior communication cerebral, and anterior cerebral and middle cerebral artery aneurysm.
Conclusion : The common location of cerebral aneurysm is anterior communicating artery aneurysm. There are correlations between the most thickness region of A and D region with anterior communicating aneurysm and the posterior circulation aneurysm, and the correlation between intracerebral hemorrhage and anterior communicating aneurysm, posterior communicating aneurysm, and middle cerebral artery aneurysm.
