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.
Material and Method: Over a 3-year period, 32 potential LRLT donors 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 (> 5 mm) accessory right hepatic veins and 11/11 (100%) significant segment VIII
vein draining to middle hepatic vein were detected.
Conclusion : CTA provided an excellent preoperative depiction of hepatic vascular anatomy in LRLT donors.
