Lu DS Objective: To assess the utility of CT angiography (CTA) in preoperative mapping of hepatic vascular anatomy in adult-toadultliving 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 wereretrospectively 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 VIIIvein draining to middle hepatic vein were detected.
Conclusion: CTA provided an excellent preoperative depiction of hepatic vascular anatomy in LRLT donors.
Keywords: Liver transplantation, Computed tomography (CT) angiography, Digital subtraction angiography
