DIAGNOSTICS METHOD FOR PORTAL PERFUSION INSUFFICIENCY OF HEPATIC SINUSOIDS

摘要

FIELD: medicine; gastroenterology.;SUBSTANCE: in cholelithiasis patients, portal perfusion insufficiency of hepatic sinusoids is examined. To this end, sinusoidal circulation is studied by measuring probe applying to main liver mass area; additionally, interelectrode distance and patient's body surface are measured; functional test of passive venous return is conducted by lower extremities lifting at 30° angle during 1 minute, whereupon hepatic index (HI) is calculated based on original formula. If HI value is more than 0.21 l/min/m², portal perfusion insufficiency of hepatic sinusoids is diagnosed.;EFFECT: method is noninvasive, sensitive, fast-executable; it allows dynamic assessment of treatment conducted in chronic liver conditions.;3 ex, 3 tbl
