Abstract

Background: In this study, we investigated the relationship between the portal vein and hepatic artery variations and the remaining liver volume in living donors in liver transplantation.

Materials and methods: In the study, triphasic abdominal CT images of 180 live liver donor candidates were analyzed retrospectively. Portal veins were divided into four groups according to the Nakamura classification and seven groups according to the Michels classification. The relationship between vascular variations and remnant liver volume was compared statistically.

Results: According to the Nakamura classification, there were 143 (79.4%) type A, 23 (12.7%) type B, seven (3.9%) type C and seven (3.9%) type D cases. Using the Michels classification, 129 (71%) type 1, 12 (6.7%) type 2, 24 (13%) type 3, two (2.2%) type 4, 10 (5.6%) type 5, one (0.6%) type Six and two (1.1%) type 7 cases were detected. There was no significant difference in the percentage of the remaining volume of the left liver lobe between the groups (p = 0.055, p = 0.207, respectively).

Conclusions: Variations in the hepatic artery and portal vein do not affect the remaining liver volume in liver transplantation donors.
