Abstract
- CT is now well established for the initial examination of the ruptured intracranial aneurysm. Aside its rolein the detection of subarachnoid blood, its uses include prediction of aneurysm location and identification ofcomplications. Although its role as an indicator of preoperative prognosis is not certain, it might be expectedthat the extent of bleeding would correlate with the preoperative clinical grade and severity of vasospasm. CT andangiographic findings in 34 patients with subarachnoid hemorrhage (SAH) due to proven intracranial aneurysms wereanalyzed for prognostic significance in relation to the clinical grade, anatomic extent of SAH and severity ofvasospasm thet developed preoperatively. The results were as follows; 1. Male to female ratio was 0.9:1 and themost prevalent age group was 41 to 60 years. 2. The locations of the aneurysm, in order of frequency, were ;anterior cerebral artery(ACA) and anterior communicating artery(A-com.) aneurysm in 20 cases(58.8%), middlecerebral artery(MCA) in 7 cases(20.6%), posterior communicating artery(p-com.) and internal carotid artery in 5cases(14.7%). 3. The diameter of the most common of the intracranial aneurysm was 3 to 6mm in 14 cases(40.0%). 4.There was direct correlation between CT classification, severity of clinical grade and vasospasm. 5. Inconclusion, CT is useful as a prognostic indicator in intracranial aneurysm patient.
