Title: Multi-slice CT Angiography in the Classification of Hepatic Vessel Variations in Right Hepatic Lobe Donor in Vivo for Liver Transplantation
Abstract: Objective:To discuss the clinical application and its value of multi-row detector CT angiography (MDCTA) in the evaluation of hepatic vessel anatomy of potential liver donors in vivo for liver transplantation (LDLT).Methods:One hundred and eight consecutive potential right lobe donors in vivo underwent tri-phasic CT angiography (arterial,portal,and hepatic venous phases).All source and reconstructed images were evaluated for hepatic vasculature anatomy.The anatomic variations of arterial system,portal venous system,and hepatic veins were classified according to Michels system,Akgul system and Nakamura system respectively.In 45 donors with right hepatic hemi-lobectomy,the CT and surgery fin-dings were compared.Results:Hepatic arteries and veins,portal veins in all 108 potential donors were revealed clearly on MDCTA.According to the Michels classification for hepatic artery,there were type Ⅰ (n=64,59.3%);type Ⅱ (n=9,8.3%);type Ⅲ (n=13,12.0%);type Ⅳ (n=4,3.7%);type Ⅴ (n=11,10.2%);type Ⅵ (n=3,2.8%);type Ⅷ (n=2,1.9%);and type Ⅸ (n=2,1.9%).According to the akgul classification for portal vein,there were type A (n=87,80.6%);type B (n=15,13.9%);type C (n=4,3.7%);and type E (n=3,2.8%).According to the Nakamura classification for hepatic vein,there were type 1 (n=73,67.6%);type 2 (n=24,22.2%) and type 3 (n=11,10.2%).CT angiography findings were in accordance with the surgery in all 45 donors.Conclusion:MDCTA can successfully show the hepatic vascular anatomy in potential liver donors in vivo,which plays an important role in the clinical application of LDLT.
