Porcine model for the study of liver regeneration enhanced by non-invasive 13C-methacetin breath test (LiMAx test) and permanent portal venous access

Portal venous catheter and liver resection.
(A) Segmental anatomy of the porcine liver. Caudate lobe: Segment (I). Left lateral lobe: Segments (II) and (III). Left medial lobe: Segment (IV). Right medial lobe: Segments (V) and (VIII). Right lateral lobe: Segments (VI) and (VII). The white area represents the resected extend of three liver lobes and the grey area defines the future liver remnant (FLR); (*) representing the additional partial resection area of the right lateral liver lobe in order to achieve a FLR of approx. 50% is marked with an asterix (*). (B) Anatomy of the porcine following major liver resection, the asterix (*) again marks the potential additional resection area. (C) Anatomic situs prior to and (D) after major liver resection in the minipig. (E) Presentation of the superior mesenteric vein/portal vein following implantation of a 4–6 F tapered portal venous catheter. (F) Liver with hypertrophic right liver lobe (marked **) 30 days after liver resection.
