Figure 5.2.8 Congenital Intrahepatic Shunt—Right Divisional (Canine) CT
1y FS Doberman Pinscher with suspected
portosystemic shunt. Transverse images
(a–d) are ordered from caudal to cranial.
There is a large, tortuous anomalous vessel
arising from the right side of the portal vein
and traveling through the right liver lobes to
the caudal vena cava (b,c: arrows). The ves-
sel was visible on ultrasound images in the
cranial liver (e: arrows). A 3D rendering from
the ventral aspect demonstrates the shape
of the shunt vessel (f: arrow). See page 507

6mo MC Labrador Retriever with failure to gain weight. Preoperatively, there are multiple small, tortuous vessels within the hepatic
parenchyma (b: arrows), cranial to the main shunt vessel (a). After partial shunt occlusion with a stent (c: open arrow) and coil emboliza-
tion, the multiple anomalous vessels have increased in diameter (c: arrows). See page 507 for Legend for Figures 5.2.1–5.2.18.
