由肝脏疾病引起的大脑功能障碍多半以门腔循环性脑病为特征,它可表现为初期的隐匿性病变至最终发生肝性昏迷。近年来可将引起肝性昏迷的原因分为急性肝衰竭(内因性昏迷)和慢性肝衰竭(外因性昏迷)两大类。病因和发病机理引起肝性昏迷的原因见表1。长期来门腔循环性脑病的发病机理尚未完全阐明,对各种病理因素的共同影响也了 Most of the brain dysfunction caused by liver disease is characterized by recurrent encephalopathy, which manifests itself as an initial occult lesion to the eventual hepatic coma. In recent years, the causes of hepatic coma can be divided into acute liver failure (internal coma) and chronic liver failure (exogenous coma) two categories. Causes of etiology and pathogenesis of hepatic coma in Table 1. Long-term pathogenesis of recurrent encephalopathy has not yet been fully elucidated on the common impact of various pathological factors also
