肝肺综合征(Hepatopul monary syndrome,HPS)是肝硬化的常见并发症,也可发生于非肝硬化的门脉高压症[1]及无肝硬化、无门脉高压的急、慢性病毒性肝炎[2]。肝肺综合征在慢性肝病中发病率达15%～20%[3],起病隐匿,临床表现缺乏特异性,早期诊断困难,容易误诊。现将我科2003-01-2009-12收治的6例肝肺综合征误诊情况分析如下。 Hepatopulmonary syndrome (HPS) is a common complication of cirrhosis, and can also occur in non-cirrhotic portal hypertension [1] and in acute and chronic cirrhosis without portal hypertension, chronic viral hepatitis [ 2]. Hepatopulmonary syndrome in the incidence of chronic liver disease in up to 15% to 20% [3], insidious onset, the lack of specificity of clinical manifestations, early diagnosis difficult and easily misdiagnosed. Now my department 2003-01-2009-12 admitted to the 6 cases of liver and lung syndrome misdiagnosed as follows.
