title: [Hepatopulmonary syndrome in patients with advanced hepatic disease: study of a series of 24 cases].
abstract: OBJECTIVE
  To describe the characteristics observed in patients diagnosed of hepatopulmonary syndrome (HPS) waiting for orthotopic liver transplantation and those who underwent liver trasplantation.
  
  
  METHODS
  An observational prospective descriptive study was carried out of patients waiting for liver transplantation in whom data of liver illness and lung function tests were analyzed.
  
  
  RESULTS
  107 patients of 53.69 years average age were studied (7.7 standard deviation). 24 of them (22.4%) had criteria of HPS. Ortodeoxia was present in the 34% of cases. The lung function tests were normal. In the comparative study between patients with HPS and no HPS, differences in diffusion were found (7.1 vs. 8.6 mmol/min/kPa; p = 0.04), as well as in the shunt (8% vs. 5.3%; p = 0.05) and the forced expiratory volume in one second (2,390 vs. 2,743 ml; p = 0.03). Seven patients were transplanted with correction of oxygenation and vascular dilatations in all of them.
  
  
  CONCLUSIONS
  HPS is a frequent illness in patients waiting for orthotopic liver transplantation. The main alteration in the blood oxygenation seems owe to shunt, and the diffusion tests is the analysis that could best differentiate patients with HPS. Orthotopic liver transplantation corrects the syndrome in all cases.
