Article Abstract
This article offers an overview of congenital and acquired vascular anomalies involving the portal venous system in dogs and cats, as determined by multidetector-row computed tomography angiography. Congenital absence of the portal vein, portal vein hypoplasia, portal vein thrombosis and portal collaterals are described. Portal collaterals are further discussed as high- and low-flow connections and categorized in hepatic arterioportal malformation, arteriovenous fistula, end-to-side and side-to-side congenital portosystemic shunts, acquired portosystemic shunts, cavoportal and porto-portal collaterals. Knowledge of different portal system anomalies helps understand the underlying physiopathological mechanism and is essential for surgical and interventional approaches.

Hepatic insulin clearance is essential for maintaining glucose homeostasis and is closely linked to metabolic disorders such as obesity, insulin resistance, and diabetes. Accurate measurement of insulin clearance is vital for understanding the underlying mechanisms of these conditions. This protocol presents a straightforward and user-friendly hepatic perfusion procedure in mice, specifically designed to directly evaluate the hepatic insulin clearance rate.

Introduction: Acute appendicitis and acute cholecystitis are two of the most commonly encountered surgical entities. Multiple hypotheses are behind their coexistence, which include pathogen predilection, and mucosal ischemia inducing portal vein bacteremia as the management of uncomplicated acute cholecystitis and acute appendicitis is surgical, for which a single operation for synchronous presentation is effective. Here, we report a case with coexistent acute cholecystitis and acute appendicitis managed at our institution.

Portal hypertension is a hemodynamic abnormality that complicates the course of cirrhosis, as well as other diseases that affect the portal venous circulation. The development of portal hypertension compromises prognosis, especially when it rises above a certain threshold known as clinically significant portal hypertension (CSPH). In the consensus conference on Portal Hypertension promoted by the Spanish Association for the Study of the Liver and the Hepatic and Digestive diseases area of the Biomedical Research Networking Center (CIBERehd), different aspects of the diagnosis and treatment of portal hypertension caused by cirrhosis or other diseases were discussed.

Congenital extrahepatic portosystemic shunt, also known as Abernethy malformation, is a rare anatomic vascular malformation. Patients with Abernethy malformation may present with abdominal pain, abnormal liver function tests, hepatopulmonary syndrome, pulmonary hypertension, and/or portosystemic encephalopathy. Accurate identification of the shunt and portal vein and effective management of complications is vital in these patients.

Background And Aims: We assessed clinical, procoagulant and genetic risk factors and clinical outcomes in dabigatran-treated patients with non-tumoural acute and acute-on-chronic portal vein thrombosis (PVT).
Methods: Patients with a new diagnosis of non-tumoural acute and acute-on-chronic PVT between January 2021 and January 2024 (aged ≥ 18 years) in those without/with cirrhosis (Child-Pugh (CP)-A/B/C ≤ 10) were started on dabigatran and followed and compared with those on vitamin K antagonist (VKA) and untreated individuals.
Results: Dabigatran was prescribed in 119 patients with PVT type 1 (61, 51.
