title: Are there any similarities in the hepatic vascular anatomy among blood relatives?
abstract: OBJECTIVE
  The existence of similarities in the hepatic vascular anatomy among blood relatives (BR) have never been studied before. Since in living donor liver transplantation (LDLT), the donor may be a BR, an opportunity is available to assess whether there are similarities in the hepatic vascular anatomy among BR.
  
  
  METHODS
  We conducted an analysis of 61 LDLT during the period from January 2004 to August 2008. Based on preoperative multi-detector computed tomography data, the hepatic arteries (HA) were classified into 4 groups, the portal vein (PV) was classified into 2 groups and the right hepatic vein (RHV) was classified into 2 groups. The data of each group were then compared between BR (n=47) and NBR (n=14).
  
  
  RESULTS
  With regard to the HA anatomy, 30 cases (68%) of the BR donor matched that of the recipient and 9 cases (69%) in the NBR donor. The PV anatomy was matched in 41 cases (87%) of BR donor and 11 cases (79%) in the NBR donor. The anatomy of the RHV was matched in 25 cases (53%) in the BR donor and 9 cases (64%) in NBR donor. There was no significant difference in all contexts.
  
  
  CONCLUSIONS
  No similarities were therefore observed in the hepatic vascular anatomy among BR.
