Fluoroscopy-guided transvenous femoral renal transplant biopsies: a monocentric retrospective study about 109 consecutive patients.

Objectives: Renal transplant biopsy remains the gold standard for etiological diagnosis of graft dysfunction and subsequent management. When percutaneous renal biopsy (PRB) is contraindicated due to bleeding risk or limited percutaneous access, the fluoroscopy-guided transvenous femoral renal transplant biopsy (TFRB) might be a valuable alternative. This study aims to describe the TFRB technique, its safety, and efficacy.

Safety and efficacy of percutaneous arterial port Implantation for Hepatic Arterial Infusion Chemotherapy.

Objectives: Approximately 40% of patients with colorectal cancer will develop liver metastases. Hepatic arterial infusion chemotherapy (HAIC) represents a valuable treatment option, with curative, palliative, or adjuvant intent. The aim of our study was to describe technical considerations, safety, and oncological outcomes of patients receiving HAIC.

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 (i.

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.
