How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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.
