REVERSAL OF HEPATIC ALPHA-1-ANTITRYPSIN DEPOSITION AFTER PORTACAVAL SHUNT

End-to-side portacaval shunts were carried out in three children with the liver disease of alpha-1-antitrypsin deficiency and complications of portal hypertension. Their clinical courses have been stable for 31/2 to almost 7 years. Postoperative liver biopsy material from two of the patients showed the typical histopathological changes caused by portal diversion, as well as an apparent reduction in the quantity of alpha-1-antitrypsin particles in the hepatocytes. The metabolic changes caused by portal diversion have apparently created a more favourable equilibrium between the synthesis and excretion of the abnormal alpha-1-antitrypsin. © 1983
