title: Clinical outcome of idiopathic hepatic parenchymal infarct following living donor liver transplantation.
abstract: OBJECTIVE
  The aim of the present study was to examine the clinical course of nonvascular hepatic ischemia following adult living donor liver transplantation (LDLT).
  
  
  METHODS
  This retrospective study reviewed the medical records of 1782 patients who underwent LDLT from January 2003 to September 2010. Nine subjects (0.5%) suffered idiopathic hepatic parenchymal infarcts (IHPI) classified according to the morphology and extent of the infarcted area as peripheral or central.
  
  
  RESULTS
  Increased levels of liver enzymes were observed in all IHPI patients. Liver cell damage closely correlated with the extent of the infarcted area. Most patients with peripheral-type IHPI showed favoarable spontaneous recovery, occasionally requiring liver support with plasmapheresis or a prolonged period. By contrast, 2 patients with central-type IHPI died due to progressive expansion of the infarcted area with subsequent graft failure.
  
  
  CONCLUSIONS
  In the present study the incidence of IHPI following LDLT was 0.5%. The severity of the infarct depended upon its location and size; central-type IHPI showed a worse prognosis. Thus, special attention should be paid to patients showing a central-type infarction.
