Aim. To analyze anatomic variants of arterial and venous blood supply of liver in potential liver donors by using of CT-angiography (CTA). Material and methods . CTA data of 151 potential donors have been examined for the period 01.01.2016-01.01.2018. Non-ionic iodine-containing (320 mg/ml) contrast agent was used at a dose of 1.4 ml/kg and infusion rate near 4.0 ml/s. Variants of arterial anatomy were classified according to N. Michels, portal vein anatomy — according to T Nakamura classification (2002). Results. N. Michels type I was the most common variant of arterial structure (n = 108, 71.5%). Types II and III were observed in 8.6% and in 7.9% of cases, respectively. Types IV and IX included the same number of donors (2.6%). Types VII and VIII were the rarest (0.7% and 1.3%). Types V, VI, X were absent. There were 7 cases (4.6%) with arterial variants which are not described by N.Michels classification. Moreover, 3 types were not previously described by other authors. Conclusion. Hepatic artery variations coincide with the classification of N. Michels as a rule (95.4%). Other anatomic variants not described in this classification were observed only in 4.6% of cases.
