PREDICTION OF POSTOPERATIVE ARTERIAL-PRESSURE AFTER PORTALIZATION OF THE ADRENAL BLOOD-FLOW

A statistical method of multidimensional regression analysis was used to study relations of systolic and diastolic arterial pressure to different parameters of preoperative examination of patients suffering from arterial hypertension and hyperaldosteronism in order to determine possibilities of predicting the surgical treatment effect. It has been established that the best prognostic combination for systolic and diastolic arterial pressure includes 3 parameters: diastolic arterial pressure, basal activity of plasma renin and the zone of the lack of the vascular pattern of the right kidney according to the angiography data. To predict the degree of the hypotensive effect of portalization, 2 types of the prognostic formulas were designed for separate computing of systolic and diastolic pressure. In predicting systolic pressure, the absolute mean-square error was equal to 11.7 mm Hg, the relative one to 7%. As to diastolic pressure, it was 7.5 mm Hg and 8%, respectively.
