Case Study

Splenocaval shunt with minor microhepatica in a 1 year old MN DSH cat

This 1 year old MN DSH cat has hepatic encephalopathy, resposive to clindamycin and lactulose. Bile acids pre 127, bile acids post 260.

DX

Splenocaval shunt with normal portal vein to vena cava ratio. Minor microhepatica.

Image Interpretation

The liver presented mild coarse architecture and increased portal markings. The portal vein revealed a 1:1 with the vena cava. This would be abnormal in dogs; however, cats can have a normal portal vein to vena cava ratio. The portal vein measured 0.55 cm, vena cava 0.47 cm. The portal vein continued deep into the cranial liver until its separation. However, a definitive splenocaval shunt was identified approximately 1.0 cm prior to the portal hilus and measured 0.5 cm in width. This decoursed dorsally and then entered the vena cava dorsally with an undulating contour. The length of the shunt was approximately 1.5 cm with a width of 0.5 cm.

Outcome

Recommend surgical intervention with ameroid constrictor therapy and concurrent
liver biopsy +/- renal biopsy.
