Plain-English summary
A 5-year-old cat with an intrahepatic portosystemic shunt (a condition where blood bypasses the liver) underwent surgery using an ameroid constrictor to close the shunt. After the procedure, the cat showed significant improvement, with symptoms resolving and no need for medication or special diets. Among the nine dogs treated, most also recovered well, although one dog had to be euthanized due to unrelated health issues. Overall, the use of ameroid constrictors was found to be a safe and effective treatment for this condition in both dogs and cats.

Abstract
OBJECTIVE: To report outcome after ameroid constrictor (AC) use for single intrahepatic portosystemic shunts (IPSS). STUDY DESIGN: Retrospective study. ANIMALS: Nine dogs and 1 cat. METHODS: Medical records (1999-2003) of dogs and cats with surgically confirmed IPSS were reviewed. Recorded data was: breed, sex, weight, age at surgery, clinical signs, serum biochemical and hematologic data, shunt anatomy, AC size, hospitalization, complications, and owner perception of their animal's response to surgery. Owners were contacted twice postoperatively (between 20 and 75 months) and asked to complete a simple questionnaire. RESULTS: With this technique, complication rate was low and postligation neurologic dysfunction was not observed. In the cat and 7 dogs, clinical signs attributed to IPPS resolved and animals were fed a non-prescription diet without medication. One dog died suddenly 18 months after surgery from causes unrelated to hepatic disease. One dog was euthanatized 23 months after surgery because of repeated, increasingly refractory episodes of hepatic encephalopathy. CONCLUSION: AC provides a safe and effective method for occlusion of some IPPS. CLINICAL RELEVANCE: AC should be considered for occlusion of some IPPS in dogs and cats.
