title: [Risk factors predicting the prognosis of orthotopic liver transplantation in hepatopulmonary syndrome].
abstract: OBJECTIVE
  To observe the effect of orthotopic liver transplantation (OLT) on hepatopulmonary syndrome (HPS) and investigate risk factors predicting the prognosis of OLT.
  
  
  METHODS
  Twenty-six cases of HPS and 30 cases of non-HPS were analyzed treated from April 2004 to January 2006. Survival rates after OLT were compared and risk factors predicting the prognosis of OLT in HPS were researched by univariant and COX analysis.
  
  
  RESULTS
  The 28 days survival rate in HPS after OLT was 76.9% (20/26), half a year survival rate and one year survival rate were both 61.5% (16/26). Whereas the one year survival rate of patients without HPS was 100%(P < 0.05). By univariant analysis, shunt of (99)Tc(m)-labeled macro-aggregated albumin in lungs, PaO2 and PaO2/FiO2 in room air before operation were relative to the prognosis of peri-operative period and half a year outcome after OLT in HPS (P < 0.05). Shunt of (99)Tc(m)-labeled macro-aggregated albumin in lungs (OR = 1.182, P = 0.001), and mechanical ventilation time (OR = 1.003, P = 0.053) after OLT were independent risk factors predicting the prognosis of OLT in HPS by COX analysis. Shunt of (99)Tc(m)-labeled macro-aggregated albumin in lungs > or = 28.4%, or PaO2 < or = 56 mm Hg (1 mm Hg = 0.133 kPa) before OLT predicted the poor outcome of OLT in HPS. The sensitivity were 83.3% and 85.0% respectively, and the specificity were 95.0% and 83.3% respectively.
  
  
  CONCLUSIONS
  OLT is an effective treatment for HPS.Shunt of (99)Tc(m)-labeled macro-aggregated albumin in lungs before OLT and mechanical ventilation time after OLT were independent risk factors for the prognosis of OLT in HPS.
