FIELD: medicine. SUBSTANCE: method involves analyzing combinations of predictionsignificant signs. Discriminant function Y is calculated as the following formula 
where X1 is somatic pathology expressive level: 1 denotes lack or a vaguely marked form, 2 denotes marked forms, 3 denotes distinctly marked forms; X2 is the clinicoanatomical hemorrhage form: 1 denotes intracranial hematoma to 50 ml not aggravated by brain dislocation; 2 denotes intracranial hematoma more than 50 ml aggravated by brain dislocation and/or liquor- conducting path tamponade or occlusion; X3 is the intracranial hypertension: 1 denotes lack thereof; 2 denotes vaguely marked forms; 3 denotes marked forms; 4 denotes distinctly marked forms; X4 is the hydrocephalia: 1 denotes lack thereof; 2 denotes vaguely marked forms; 3 denotes distinctly marked forms; X5 is patient state severity at the surgical operation day: 1 - compensated one, 2 - subcompensated one, 3 - decompensated one; X6 is the time passed after hemorrhages to the moment the surgical intervention has been done: 1 - 1-3 days, 2 - 4-7 days, 3 - 8-14 days, 4 - 15-21 days, 5 - more than 21 days. The value of Y being equal to or greater than 0, favorable operation outcome is to be predicted; Y<0 - lethal outcome is to be predicted. EFFECT: simplified prognosis method; high reliability of prognosis. 3 tbl
