Temporary Flow Diversion in Oncological Embolization Procedures Using Degradable Starch Microspheres.

Objectives: This study aims to report on the application of degradable starch microspheres to provide flow diversion by means of temporary embolization of healthy tissues in oncological endovascular procedures when tumor feeding vessels are not selectively accessible.

Methods: This is a multicenter retrospective analysis of patients undergoing visceral embolization procedures of malignancies. The inclusion criteria were as follows: flow diversion performed by injection of degradable starch microspheres, visceral embolization procedures with unfeasible superselective catheterism of the target, and a malignant pathology.

A case report of hepatic inflammatory myofibroblastic tumor in a pediatric patient: diagnostic challenges and management strategies.

Purpose: The aim of this study is to present a case of inflammatory myofibroblastic tumor (IMT) of the liver in a 4-year-old girl. We will discuss the diagnostic challenges, the role of the radiologist in differential diagnosis, treatment modalities, and clinical outcomes.

Methods: A case report of a 4-year-old girl with IMT of the liver is presented.

A Trifecta-Based Evaluation of Patients Treated with Percutaneous Thermal Ablation of Small Renal Masses.

Scoring metrics are important to compare outcomes of different percutaneous treatments for small renal masses (RMs). The concept of trifecta (no complications, kidney function preservation, and absence of local recurrence) has been recently introduced in percutaneous thermal ablation of RM. In this context, previous studies have shown that cryoablation (CA) and microwave ablation (MWA) have similar outcomes.

Percutaneous microwave ablation of HCC: comparison between 100 and 150 W technology systems.

Purpose: To evaluate the differences in efficacy and safety between the 100 and 150 W percutaneous microwave ablation (MWA) systems in the treatment of hepatocellular carcinoma (HCC).

Methods: We retrospectively reviewed all patients who underwent percutaneous MWA (Emprint™ HP Ablation System, Medtronic) between January 2021 and May 2023. We divided the cohort into two groups: Group 1, treated with MWA at 100 W power system, and Group 2, treated with 150 W one.

Left radial vs right femoral: comparison between arterial accesses in c-TACE procedures in terms of operator radiations exposure and patient comfort.

Purpose: This multicenter prospective study aims to compare transradial access versus transfemoral access in conventional transarterial chemoembolization (c-TACE) procedures, focusing on operators radiations exposure, patients comfort, technical success and vascular access complications.

Materials And Methods: Patients were affected by hepatocellularcarcinoma (HCC) in intermediate stage or previous stages unfit for ablation and/or surgery; they were randomized into two groups according to arterial access site (Group F: right femoral access in standard position; Group R: radial access with left arm abduced 90°). Overall fluoroscopy time was recorded.
