Figure 9. Animal 3. Photomicrographs show an embolized segment from the left lobe obtained 3 days after embolization. A, Low-magnification image shows a PVA particle (arrowhead) within a portal vein branch. Horizontal arrow = a portal triad, vertical arrow = a central vein. (Hematoxylin-eosin stain; original magnification, x50.) B, Higher magnification image shows the portal triad in more detail. The PVA particle, a bile duct (BD), and a hepatic arterial branch (HA) are shown. An inflammatory cell infiltrate surrounds the PVA particle. (Hematoxylin-eosin stain; original magnification, x125.)
