Plain-English summary
A 4-year-old male Maltese was brought in for evaluation of bladder stones and had high bile acid levels, indicating liver issues. Imaging tests showed he had a portosystemic shunt, which is an abnormal blood vessel that bypasses the liver. The dog underwent surgery using a technique called cellophane banding to correct the shunt. After the surgery, follow-up tests showed that the shunt was successfully closed, and his bile acid levels improved significantly. He had no problems at the six-month check-up, indicating a successful recovery.

Abstract
A 4-year-old, 1.8 kg, male, castrated Maltese was presented for evaluation of urolithiasis. Urinary calculi were composed of ammonium biurate. Preprandial and postprandial bile acids were 44.2 and 187.3 micromol/l, respectively (reference ranges 0-10 and 0-20 micromol/l, respectively). Single-phase contrast-enhanced computed tomography angiography (CTA) with volume-rendered imaging (VRI) was obtained. VRI revealed a portocaval shunt originating just cranial to a tributary of the gastroduodenal vein and draining into the caudal vena cava at the level of the epiploic foramen. CTA revealed a 3.66 mm-diameter shunt measured at the level of the termination of the shunt and a 3.79 mm-diameter portal vein measured at the level between the origin of the shunt and the porta of the liver. Surgery was performed using cellophane banding without attenuation. Follow-up single-phase CTA with VRI was obtained 10 weeks after surgery. VRI revealed no evidence of portosystemic communication on the level of a cellophane band and caudal to the cellophane band. CTA demonstrated an increased portal vein diameter (3.79-5.27 mm) measured at the level between the origin of the shunt and the porta of the liver. Preprandial and postprandial bile acids were 25 and 12.5 micromol/l, respectively (aforementioned respective reference ranges), 3 months post-surgery. No problems were evident at 6 months.
