| Popis: | Objectives To compare estimated remnant liver volume (ERLV) ratios among the major main portal vein (MPV) variants. Methods Eighty-five potential donors underwent multidetector CT examination. Arterial, portal and hepatic venous phase images were obtained. CT volumetric measurements were performed by using summation-of-area method. MPV variants were classified into three groups. In type 1 (group 1), the MPV branches into the right portal vein (RPV) and the left portal vein (LPV). In type 2 (group 2), the MPV trifurcates into the right anterior portal vein (RAPV), right posterior portal vein (RPPV) and LPV. In type 3 (group 3), the RPPV arises from the MPV as a first branch, and the RAPV emerges directly from the LPV. Results No differences were observed between groups 1 and 2 with respect to ERLV ratios. However, significant differences were discovered between groups 1 and 3 and between groups 2 and 3 (p |
