Abstract
Among 160 cases of verified ruptured saccular aneurysms, we investigated 82 cases received direct surgery within 72 hours from ictus.
The important factors of neurological and CT findings on admission influencing on operative outcome were analyzed statistically.
To estimate the neurological condition, we used Hunt & Hess' Grading, Japan Coma Scale and Glasgow Coma Scale.
Location of cisternal clot, degree of SAH over the cortex, shape of the third ventricle, ventricular reflux, intracerebral hematoma and intraventricular hematoma were selected as indicators of acute stage of SAH. Based on the statistical analysis of these factors of CT, we devised CT score.
Our “CT score” correlated well with surgical outcome and the severity of clinical vasospasm in comparison with neurological grading system.
