説明

Using the technique of percutaneous transhepatic portal vein catheterization, separate measurement of intra- and extrahepatic shunts was possible. It involves injection of 99mTc-macroaggregated albumin (MAA) at the beginning of splenic vein and of 131I-MAA in the portal trunk, followed by scanning of liver and lungs, and measurement of count of each nuclide over the set areas of these organs. Measurement of intrahepatic shunt index was carried out in 18 cases with liver disease. Intra- and extra-hepatic shunt indeces were measured in 9 out of 18 cases. Intrahepatic shunt indeces were 1.6 to 78.4% in liver cirrhosis (14cases), 4.6% in idiopathic portal hypertension (1 case), 1.0% in intrahepatic cholestasis (1case) and 4.2 to 5.4% in hepatic steatosis (2cases). Extrahepatic shunt indeces were O to 49.9% in liver cirrhosis and 1.5% in hepatic steatosis. The intrahepatic shunt indeces seemed to correlate very closely with ICG retention, and with the presence of jaundice, indicating the value of shunt measurement in assessing liver function and prognosis. <BR>Extrahepatic shunt indeces seem to correlate with the size of collaterals opacified by portography and tend to be high in the presence of esophageal varices.
