The blood flow volume was measured in 20 patients with liver disease using an ultrasonic duplex system (Toshiba SAL50A\/SDL-01A). The portal venous pressure was also measured via a 3F catheter using a transducer. The catheter was placed in position by substituting it for a 25-gauge needle that had been inserted into the portal vein under ultrasonic guidance percutaneously and transhepatically.<\/jats:p>\n            <jats:p>Splenic arterial occlusion caused a drop in splenic venous blood flow from 708 \u00b1 487 to 241 \u00b1 155 ml per min, in portal venous blood flow from 993 \u00b1 439 to 807 \u00b1 419 ml per min and in portal venous pressure from 17.4 \u00b1 7.2 to 14.4 \u00b1 6.1 mm Hg. The latter two reductions were less than expected from the decrease in the splenic venous blood flow volume. This phenomenon was caused by an increase in the mesenteric venous blood flow from 475 \u00b1 126 to 630 \u00b1 270 mm per min.<\/jats:p>\n            <jats:p>This increase may be due to a compensatory mechanism under the control of a regulatory loop in the liver or portal vein, and there seems to be a relationship between splenic and intestinal circulation in portal hypertension that maintains hepatic circulation.<\/jats:p>\n
