متن کاملHemodialysis-related portal-systemic encephalopathy.
Hemodialysis-related portal-systemic encephalopathy (HRPSE) is characterized by the presence of portosystemic encephalopathy without liver dysfunction, usually caused by changes in the systemic venous flow related to hemodialysis. We herein describe the case of a 75-year-old woman who developed hepatic encephalopathy five years after the initiation of hemodialysis. Abdominal contrast-enhanced c...
متن کاملAmmonia intoxication in portal systemic encephalopathy.
Portal systemic encephalopathy (PSE) comprises of five major features, of which ammonia intoxication of the central nervous system is the only specific feature. Ammonia is a key intermediate in the metabolism of nitrogen. Oxidative deamination of aminoacids is one of the major ammonia producing pathways. It occurs predominantly in the liver, to a lesser extent kidneys and also in the brain. The...
