Introduction: Hepatopulmonary syndrome (HPS) is an important complication of liver cirrhosis associated with worse prognosis and increased mortality. It is probably underdiagnosed, which is relevant due to the therapeutic implications associated with its identification. Aims: To determine the prevalence and prognostic impact of HPS in patients with liver cirrhosis. Patients and Methods: Prospective study of 48 consecutive patients with liver cirrhosis (77% male, 59 years average age, 85% alcoholic aetiology, Child-Pugh A-29%, B-46%, C-25%), evaluated by arterial blood gas analysis and, when abnormal, contrast echocardiography. The diagnosis was established if increased alveolar-arterial oxygen gradient and pulmonary vasodilatation were simultaneously present. All patients, with and without HPS, were followed. Results: From 48 patients studied, 4 (8,3%) had HPS. Among these patients, advanced stages of cirrhosis were overrepresented and none had respiratory symptoms. With a median follow-up of 7,8 months, the mortality in the HPS subgroup was significantly and independently higher (75% versus 13,6% in the controls, p=0,017). Conclusions: HPS is relatively frequent in patients with advanced liver cirrhosis. Symptoms are not a sensitive marker of the disease, suggesting it should be investigated systematically. It was identified as an independent prognostic factor, associated with higher mortality.
