Non selective beta-blockers prevent PHT-related complications occurrence in HCC patients with esophageal varices treated by TACE.

Introduction: We aimed to investigate the parameters associated with portal hypertension (PHT)-related complications occurrence in hepatocellular carcinoma (HCC) patients treated by transarterial chemoembolization (TACE), with a focus on non-selective beta blockers (NSBBs) due to their impact on preventing liver decompensation.

Methods: We included all patients with HCC for whom endoscopy was available the day of first TACE (2013-2023). The occurrence of PHT-related complications was defined as the appearance of ascites, acute variceal bleeding or hepatic encephalopathy (HE) post-TACE treatment and prior to HCC progression.

Impact of conventional and biological disease-modifying anti-rheumatic drugs on arterial lesions in Takayasu arteritis.

Background: The definition of Takayasu arteritis (TAK) remission and disease activity is still unclear. Vascular imaging is an essential tool for following-up patients. Herein, we aimed to compare the evolution of vascular lesions (ie vessel wall thickening and stenosis) under conventional disease-modifying anti-rheumatic drugs (cDMARDs) relatively to biological DMARDs (bDMARDs) in TAK patients followed with the same CT angiography modalities.

Local and distant response to intratumoral immunotherapy assessed by immunoPET in mice.

Background: Despite the promising efficacy of immune checkpoint blockers (ICB), tumor resistance and immune-related adverse events hinder their success in cancer treatment. To address these challenges, intratumoral delivery of immunotherapies has emerged as a potential solution, aiming to mitigate side effects through reduced systemic exposure while increasing effectiveness by enhancing local bioavailability. However, a comprehensive understanding of the local and systemic distribution of ICBs following intratumoral administration, as well as their impact on distant tumors, remains crucial for optimizing their therapeutic potential.

Coil Embolization of Variant Hepatic Arteries During Percutaneous Arterial Port Catheter Placement for Intraarterial Chemotherapy: Analysis of Intrahepatic Perfusion Redistribution and Treatment Efficacy.

Purpose: The purpose of this study was to analyze the intrahepatic perfusion redistribution after embolization of hepatic arterial variants during percutaneous arterial port catheter placement as well as to investigate the treatment efficacy of intraarterial chemotherapy in perfusion redistribution-dependent compared to redistribution-independent liver areas.

Materials And Methods: This retrospective study included 62 patients (67.7% males, mean age of 56 ± 12 years).

Middle meningeal artery embolization reduces the post-operative recurrence rate of at-risk chronic subdural hematoma.

Background: Embolization of the middle meningeal artery (MMA) has emerged as a potential treatment of chronic subdural hematomas (CSDHs).

Objective: To evaluate the impact on recurrence rate of postsurgical embolization of CSDH in patients with a higher than average risk of recurrence.

Methods: A monocentric retrospective study was performed on retrospectively collected data.

Safety of vertebral augmentation with cranio-caudal expansion implants in vertebral compression fractures with posterior wall protrusion.

Objectives: Vertebral augmentation (VA) has become routinely used in vertebral compression fractures (VCFs). VCFs are often associated with posterior wall protrusions (PWPs), which theoretically contraindicates vertebroplasty due to a higher risk of neurological complications. The latest generation of VA devices uses intravertebral cranio-caudal expandable implants to improve the correction of structural deformities but could also be used to prevent further PWP during cement injection.
