Figure 5.2.10 Congenital Extrahepatic Shunt—Splenocaval (Canine) CT
2y MC Yorkshire Terrier with 2‐year history of
episodic ataxia and seizures. Images a–c are
ordered from caudal to cranial. The short
extrahepatic shunt vessel arises from the
portal vein at the junction of the splenic vein
and curves dorsally and to the left to join the
caudal vena cava (d: arrow). The portal vein
decreases in diameter cranial to the shunt
exit (c: arrow). The MIP image shows the
relationship between the splenic vein and the
shunt (d). See page 507 for Legend for
Figures 5.2.1–5.2.18.
