METHOD FOR SIMULATING CORRECTION OF PORTAL HYPERTENSION IN ANIMALS Russian patent published in 1995 - IPC

FIELD: medicine. SUBSTANCE: portal hypertension is corrected by simultaneously contracting gap in arterial celiac trunk, cranial and caudal mesenterial arteries by one third of their diameters. Disclosed method of simulating correction of portal hypertension is easy-to-perform, allows lower rate of operative traumatism, avoiding risk associated with resection of intestine in post-operative period, and preserving small intestine and functional capability of participating in digestion. Scaling down rate of arterial blood flow to organs located in abdominal cavity through contracted vessels prevents initiation of collateral blood flow between celiac trunk system and cranial mesenterial artery and cranial and caudal mesenterial arteries. This allows stable correction of portal hypertension. EFFECT: lower rate of in-operation injuries, preservation of small intestine and stable corrective effect.
