Cirrhotic patients without signs of hepatic encephalopathy may have cognitive as well as rCBF alterations, which may depend upon neuronal damage due to the liver disease. We studied by means of SPECT and 99mTc-HMPAO as a rCBF tracer, whether the abnormalities of brain functional activity can be reversed by liver transplantation. Eigth, neurologically normal cirrhotic patients were selected. SPECT study was performed before and one year after successful liver transplantation. Before surgery, the SPECT study showed reductions of tracer uptake in the majority of cortical regions compared with normal controls. After surgery, tracer uptake, improved in all cortical regions to normal values.These results suggest that long-lasting liver transplantation normalizes brain functional activity of cirrhotic patients. Therefore longlasting liver disease does not produce irreversible neuronal damage.
