[Methods of excluding the liver from the general circulation for its subsequent perfusion]

Methods of exclusion of the liver from the general blood circulation for its further perfusion were studied in 316 experiments in corpses of humans and dogs. Original caval and portal canules constructed by the authors were used in 180 experimental operations in dogs weighing from 10 to 35 kg to prove the possibility of occlusion of the vena cava inferior above and below the liver to take blood from the hepatic veins and to return it into the liver after saturation with oxygen and drugs through the portal vein tributaries and hepatic artery.
