[Hepatic vein catheter technic: method for the detection of metabolic and hormonal variables in the splanchnic area].

The hepatic venous catheterization method permits calculation of net splanchnic output and uptake of substrates and hormones from their respective differences in hepatic venous and arterial concentrations as well as the rate of hepatic plasma or blood flow. Estimates of the latter are made possible by the continuous infusion technique using indocyanine green dye. With determination of splanchnic balance data at hand transsplanchnic and in part even transphepatic handling of metabolic substrates and hormones can be calculated.
