Survival Prediction of Ganglio-thalamic Hemorrhage Accompanying Intraventricular Hemorrhage Using CT Scan Indices

ABSTRACT

To develop a survival prediction model and to use it as a therapeutic guideline a series of 66 cases with ganglio-thalamic hemorrhage accompanying intraventricular hemorrhage were analyzed retrospectively. They were classified into the benign and fatal groups according to their final outcomes. Fourteen indices obtained from the initial CT scans were final outcomes. Fourteen indices obtained from the initial CT scans were subjected to multivariate discriminant analysis. The resultant discriminant function(Z) included the amount of hematoma in the parenchyme(AH), bicaudate cerebroventricular index(BCCI) maximum fourth ventricular width(FVW), and third cerebroventricular ratio(TCR) in an order of decreasing discriminating power and was as follows Z = -3.2639 + 0.3508 X 10(-1) X AH + 6.8816 X BCCI + 0.1139 X FVW-5.7794 X TCR. This function predicted survivability with accuracy of 84.9% when it was applied to the original subjects. The conclusion is that AH, BCCI, FVW, and TCR are the potent predictors of the survival of patients with ganglio-thalamic hemorrhage accompanying intraventricular hemorrhage.
