The ability of the routine head computed tomography in the detection of the non-giant intracranial aneurysms-A reappraisal
Keywords:
CT brain, non giant aneurysmsAbstract
Retrospective review of the routine CT scan of the brain of the patients who were operated for ruptured and unruptured aneurysms. Angiography was performed in every case which was studied. There were 28 ruptured aneurysms and two unruptured aneurysms. The rate of the detection of the ruptured aneurysms by CT scan depended on the size of the aneurysm, the time interval from the onset of the subarachnoid hemorrhage to the time of performing CT scan and the site of the aneurysm. The detection rate was high when the size of the aneurysms were larger than 6 mm, when CT scans was performed after 4 days of onset of subrachnoid hemorrhage and when the aneurysms were at the basilar tip and middle cerebral artery.
