title: Assessment of causes of early death after twenty years of liver transplantation.
abstract: BACKGROUND
  Postoperative poor graft function is a serious complication that can lead to graft loss requiring retransplantation or even death. The postoperative complications of primary nonfunction (PNF), early graft dysfunction (EGD), bleeding due to coagulopathy, and hepatic artery thrombosis (HAT) can lead to graft loss requiring retransplantation or even death. We determined the causes of death after liver transplantation.
  
  
  METHODS
  This was an observational descriptive study on adult liver transplant recipients from September 1991 to December 2011. The cutoff for the definition of death was 30 days after surgery. We included patients older than 18 years of age who underwent liver grafts using the piggyback technique, excluding those who had retransplantations or liver-kidney transplantations.
  
  
  RESULTS
  We analyzed 561 liver transplantations through chart review. After application of exclusion criteria we had 81 patients for analysis. Overall mortality was classified into 3 main causes: PNF (34/81; 42%), EGD (10/81; 12%), and abdominal bleeding due to coagulopathy (9/81; 11%).
  
  
  CONCLUSIONS
  Despite advances, mortality in the first 30 days after surgery is still high, mainly related to the occurrence of PNF and EGD, whose causality was associated with red blood cell transfusion (>5 U).
