Objective: Transjugular intrahepatic portosystemic shunt (TIPS) creation increases the risk of hepatic encephalopathy due to overshunting. Techniques exist to secondarily reduce the shunt for refractory encephalopathy. The purpose of this article is to describe a technique for primary TIPS restriction using a balloon-expandable stent within the transvenous hepatic track followed by deployment of a self-expanding polytetrafluoroethylene-lined stent-graft within the balloon-expandable stent to create the TIPS.
Conclusion: This technique enables control over the degree of portosystemic shunting in elective TIPS creation.

Safety and Efficacy of Portal Vein Recanalization with Creation of Intrahepatic Portosystemic Shunt (PVR-TIPS) to Treat Chronic Portal Vein Thrombosis in Non-cirrhotic Patients.

Purpose: This study assesses the efficacy and safety of Portal Vein Recanalization with Intrahepatic Portosystemic Shunt (PVR-TIPS) in non-cirrhotic patients with chronic portal vein occlusion (CPVO), cavernomatous transformation, and symptomatic portal hypertension (PH) and/or portal vein thrombotic progression.
Material And Methods: Medical records of 21 non-cirrhotic patients with CPVO and portal cavernoma undergoing PVR-TIPS were analyzed. Hemodynamic (intraprocedural reduction in portosystemic pressure gradient), clinical (data on gastrointestinal bleeding, abdominal pain, ascites, and presence of esophageal varices from imaging exams) and technical success (PVR-TIPS) assessed efficacy.

To investigate the association between overt hepatic encephalopathy (OHE) and liver pathology after transjugular intrahepatic portosystemic shunt (TIPS) creation in cirrhotic patients. From July 2015 to April 2024, 73 patients from 4 hospitals in China who received TIPS creation and liver biopsy were retrospectively enrolled in this study. Based on whether OHE occurred within 3 months after TIPS creation, the patients were categorized into OHE (n = 29) and non-OHE (n = 44) groups.

Skyrmion bags, with arbitrary topological charge Q, have recently attracted much interest, since such high-Q topological systems could open a way for topological magnetism research and are promising for spintronic applications with high flexibility for information encoding. Investigation on room-temperature skyrmion bags in magnetic multilayered structures is essential for applications and remains unexplored so far. Here, we demonstrate room-temperature creation and manipulation of individual skyrmion bags in magnetic multilayered disks.

Background: Chronic total occlusion (CTO) of the portal vein is one of the main causes of portal hypertension, which may result in life-threatening complications often managed by interventional radiology (IR). The aim of this study is to report the innovative experience with percutaneous revascularization therapy in the management of portal vein CTO in paediatric and adult patients.
Materials And Methods: From January 2020 to December 2023 consecutive paediatric and adult patients with severe portal hypertension resulting from portal vein CTO who underwent attempts at percutaneous recanalization were retrospectively reviewed.

Article Synopsis
- * It aims to provide interventional radiologists with best practice guidelines for performing TIPS, including patient selection, procedural management, and follow-up care, particularly in pediatric cases.
- * A group of European clinicians reviewed recent literature and reached a consensus to develop updated recommendations, demonstrating TIPS's proven effectiveness in treating portal hypertension and outlining safe operational practices.
