            3y M Yorkshire Terrier with obtundation and elevated bile acids. On preoperative CT angiography, a single extrahepatic shunt (a) was
            present, and cranially there was no evidence of portal vasculature. Hepatic arterial branches were visible (b: arrow), and the right liver
            was hypoplastic (b: arrowheads). Eight weeks after shunt attenuation, the right portal branch is normal in size (c: arrow), and the liver
            has increased in volume on transverse images (c: arrowheads) and comparative presurgical (d) and postsurgical (e) 3D volume render-
            ings of the liver. See page 507 for Legend for Figures 5.2.1–5.2.18.
