肝硬化患者易发生肺部病变,如支气管炎、肺部感染,胆汁性肝硬化常与致纤维性肺泡炎伴发,但大约1/3的肝硬化患者并无肺部疾病而存在着轻重不等的低氧血症。这种低氧血症伴肺内血管短路和肺灌注障碍的现象称为“肝-肺综合征”。本文通过22例肝硬化患者临床分析,探讨其发生机理。 Patients with cirrhosis are susceptible to pulmonary conditions such as bronchitis, lung infections, and biliary cirrhosis often associated with fibroalveolar alveolitis, but about one-third of patients with cirrhosis have no lung disease and are not Such as hypoxemia. This phenomenon of hypoxemia with pulmonary vascular short circuit and lung perfusion disorders is called “liver-lung syndrome.” In this paper, clinical analysis of 22 patients with cirrhosis and explore its mechanism.
