Figure 5. Graphs show laboratory values obtained before and after embolization. A series of blood samples were analyzed for evidence of hepatic or renal damage after embolization in two domestic swine (animals 2 and 3) and in four minipigs (animals 4–7). The upper and lower limits of normal levels are indicated by the dotted lines. The different animals are indicated by different symbols. ALT = alanine aminotransferase, AST = aspartate aminotransferase, u/l = IU/L.
