The hepatopulmonary syndrome
The hepatopulmonary syndrome (HPS) – a complication of liver disease – seems to be underdiagnosed, probably because of decreased awareness. HPS consists of the triade liver disease, intrapulmonary vascular dilatation and as a consequence arterial hypoxaemia. No medical therapy has proven effective perhaps with the exception of garlic, which has been effective in one controlled clinical trial. However, liver transplantation seems to improve HPS in most cases. Liver patients with unexplained hypoxaemia should be investigated for HPS.
