title: Outcomes of intrahepatic portosystemic shunts occluded with ameroid constrictors in nine dogs and one cat.
abstract: OBJECTIVE
  To report outcome after ameroid constrictor (AC) use for single intrahepatic portosystemic shunts (IPSS).
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  AC provides a safe and effective method for occlusion of some IPPS.
  
  
  CONCLUSIONS
  AC should be considered for occlusion of some IPPS in dogs and cats.
