title: Efficacy of CT angiography for preoperative vascular mapping in adult to adult living related liver transplant donors.
abstract: OBJECTIVE
  To assess the utility of CT angiography (CTA) in preoperative mapping of hepatic vascular anatomy in adult-to-adult living related liver transplant (LRLT) donors.
  
  
  METHODS
  Over a 3-year period, 32 potential LRLTdonors underwent CTA with subsequent comparison studies [digital subtraction angiography (DSA) and/or transplantation] were included in this study. Their CTA reports were retrospectively correlated with available DSA and/or operative findings.
  
  
  RESULTS
  CTA correctly predicted right lobe arterial and portal venous anatomy in 32/32 (100%) donors. In 27 donors, hepatic venous anatomy on CT was compared with operative findings. The hepatic veins were well opacified in 23/27 (85.2%) donors. Of these, 15/16 (93.8%) significant (> or =5 mm) accessory right hepatic veins and 11/11 (100%) significant segment VIII vein draining to middle hepatic vein were detected.
  
  
  CONCLUSIONS
  CTA provided an excellent preoperative depiction of hepatic vascular anatomy in LRLT donors.
