[The effect of portacaval anastomosis and liver arterialization on the oxygen supply of the normal and the cirrhotic liver].

The application of the Platinum-Multiwire Surface electrode for local oxygen determination permits the determination of microcirculatory changes in the normal and cirrhotic liver. The normal liver is capable of compensating for portal blood deprivation whereas in the cirrhotic liver shunting of portal blood leads to a striking hypoxia of the liver tissue. Lack of oxygen can be prevented by means of arterialization, but despite oxygen adaptation at the time of operation uncontrollable hyperoxygenation can occur as well.
