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.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for managing complications of portal hypertension, particularly acute variceal bleeding (AVB). While effective in reducing portal pressure and preventing rebleeding, TIPS is associated with a considerable risk of overt hepatic encephalopathy (OHE), a complication that significantly elevates mortality rates.
Aim: To develop a machine learning (ML) model to predict OHE occurrence post-TIPS in patients with AVB using a 5-year dataset.

Hemodynamic processes from the portal vein(PV) to the inferior vena cava(IVC) were mimicked for three patients with portal hypertension(PH) and the effects of stent parameters on the outcomes of transjugular intrahepatic portosystemic shunt(TIPS) were investigated through computational fluid dynamics(CFD). The liver region was simulated with porous media model and the spatial distributions of superior mesenteric vein(SMV) and splenic vein(SV) blood were solved through the Eulerian multiphase model. The present method is able to simulate the PH flow and predict the PV pressure, the stent shunt rate and the SMV blood proportion after TIPS treatment.

Trans-jugular intrahepatic portosystemic stent shunting (TIPSS) has been in use for many years with great results and many evolutions. The procedure essentially involves the insertion of a metal covert stent to create an Hepato-Hepatic portosystemic shunt. Over time, TIPSS has become the subject of many studies aimed at examining its clinical utility and evaluating the results of using TIPSS to manage complications related to portal hypertension.

Background: Chylous ascites is an uncommon condition, occurring in less than 1% of ascites cases. It results from traumatic or obstructive disruption of the lymphatic system, causing the leakage of thoracic or intestinal lymph into the abdominal cavity. This leads to the accumulation of a milky, triglyceride-rich fluid.
