Title: Value of Mutlti-slice Spiral CT in the Diagnosis of Hepatic Outflow Tract Reconstruction Manners in Adult Living Donor Liver Transplantation
Abstract: Objective To discuss the value of multi-slice spiral CT(MSCT) enhanced scan and angiography in the diagnosis of hepatic outflow tract reconstructive manners in adult living donor liver transplantation(LDLT).Materials and Methods From November 2007 to February 2008,16 recipients underwent the adult living donor liver transplantation with right lobe grafts without the middle hepatic vein.Large tributaries of middle hepatic vein and inferior right hepatic vein were reconstructed with cold-storage vein.Reconstructive types and numbers were listed as:V5(n=1),V8(n=1),V5 and V8(n=6),V5 and IRHV(n=2),V5,V8 and IRHV(n=6).Twenty-nine veins were reconstructed in 16 cases.Three-phase enhanced CT scan were performed at the period of 11 days to 1month after operation.The vein grafts were investigated by CT angiography(CTA) reconstructed with Multiplanar reconstruction(MPR),maximum intensity projection(MIP) and volume rendering(VR) techniques.All the reconstructive manners were assessed retrospectively.All the hepatic outflow tracts were detected dynamically.The enhanced behavior of liver graft was detected.Two-time of Serum bilirubin level at 2 weeks and 1month after operation were recorded.Results The inferior right hepatic vein(IRHV) and pass-by vessels which were used to reconstruct the tributaries of the middle hepatic vein could be displayed on CT images.The vessels showed unobstructed except 3 thin and 1 narrowed vessels The enhanced behavior of liver graft was varied.The degree of congestion and the serum bilirubin level decreased at 1 month after operation.Conclusion Multi-slice spiral CT can not only clearly display the pathway and stenosis of pass-by vessles and inferior right hepatic vein,but also detect the congestion degree of liver graft,which will provide useful information to guide clinical therapy.
