NEW IN JVIR: Percutaneous Radiofrequency Ablation of Perivascular versus Nonperivascular Hepatocellular Carcinomas ≤ 3 cm: Local Tumor Progression and Survival in an Inverse Probability of Treatment Weighting Analysis

🔍 Clinical Question:
To determine whether perivascular hepatocellular carcinoma (HCC) is associated with higher local tumor progression (LTP) and lower overall survival (OS) after percutaneous radiofrequency ablation (RFA) than nonperivascular HCC.

💡 Key Insight:
Perivascular hepatocellular carcinomas ≤ 3 cm showed higher local tumor progression after radiofrequency ablation. Perivascular tumors had lower overall survival compared with nonperivascular tumors. Rates of Society of Interventional Radiology (SIR) Grade C-E adverse events were comparable between the two groups.

👉 Why it matters:
These findings confirm that perivascular tumor location is associated with higher recurrence and lower survival after RFA for small HCCs, even after rigorous statistical adjustment. Identifying perivascular location should prompt careful treatment planning and consideration of adjunctive or alternative strategies.

NEW IN JVIR: Percutaneous Cryoablation of T1b Renal Tumors: A Retrospective Evaluation of Local Tumor Control, Renal Function Preservation, Adverse Events, and Ablation Margins in 80 Patients

🔍 Clinical Question:
To investigate whether achieving an intraprocedural ice-ball margin of ≥8 mm during percutaneous cryoablation (PCA) of T1b renal cell carcinoma (RCC) results in long-term local tumor control with acceptable adverse events profile.

💡 Key Insight:
Percutaneous cryoablation achieved high composite outcomes success rates (98.8%) in T1b renal cell carcinoma, ensuring effective tumor control, renal preservation, and minimal adverse events. Ablation margins of ≥8 mm were crucial for preventing residual disease in T1b lesions, reflecting histopathologic evidence of microscopic extension beyond imaging boundaries.

👉 Why it matters:
These results affirm percutaneous cryoablation's effectiveness for T1b RCC with excellent renal function preservation and low adverse event rates—qualities that position it as a frontline option for older patients with comorbidities. Achieving ≥8 mm ice-ball margins appears essential to minimizing residual disease or local recurrence.

🆕 IN : Transarterial Embolization for Refractory Adhesive Capsulitis and Related Tendinopathies: A Systematic Review and Meta-Analysis

Clinical❓: This study aimed to synthesize evidence on transarterial embolization ( ) for adhesive capsulitis and related shoulder tendinopathies to quantify pooled changes in pain, range of motion, functional scores, and safety outcomes.

🕵️Key insight: Transarterial embolization (TAE) produced large, sustained improvements in pain scores, shoulder mobility, and function for refractory adhesive capsulitis. The analysis demonstrated a favorable safety profile with 100% technical success, no severe complications, and a 2.2% moderate adverse event rate.

Why it matters 🤷: This meta-analysis provides a robust evidence base for TAE as a safe and effective minimally invasive treatment option for patients with refractory to conservative management, justifying the progression to randomized trials.

🌟NEW IN JVIR🌟: Safety and Feasibility of Intra-Arterial Treatment of Pancreatic Cancer Using an Emulsion of Ethiodized Oil plus Bumetanide in an Oncopig Model

🕵️: To evaluate the safety and feasibility of treating pancreatic tumors in an Oncopig tumor model, using bumetanide (BU)/ethiodized oil emulsion.

🔑 insight: Intra-arterial injection of bumetanide and ethiodized oil emulsion is safe in treating pancreatic tumors in Oncopigs. No pancreatitis was observed after injection into the pancreatic feeding artery. Tumors decreased in size after 1 week of treatment, with a significant reduction compared with the control group.

Why it matters🤔: This preclinical study demonstrates a safe and feasible intra-arterial approach for targeting pancreatic tumors using an anti-glycolytic emulsion, supporting further investigation into locoregional metabolic therapy for pancreatic cancer.

NEW IN : Standardized Technique for Prostatic Artery Embolization: A Delphi Consensus Study on Optimized Methods and Emerging Concepts

Clinical❓: To consolidate existing evidence and expert opinion into a structured, stepwise approach for performing ( ) in the management of benign prostatic hyperplasia ( ).

🔑 insight: An international panel of 14 experts achieved high consensus (>80% agreement) on six key procedural steps for PAE, creating a framework to address its technical complexity. Core recommendations include the use of cone-beam CT for procedural planning, embolization to complete stasis from the distal prostatic artery, and mandatory techniques to avoid non-target embolization. The panel also discussed the safety of emerging concepts like liquid embolic agents and the "coil-out" technique.

Why it matters🕵️: This consensus provides interventional radiologists with evidence-based, standardized technical recommendations aimed at optimizing outcomes, improving procedural consistency, and enhancing safety for this effective but technically demanding treatment for benign prostatic hyperplasia.

**NEW IN JVIR:** Image-Guided Thermal Ablation of Upper Pole Renal Lesions ≤4 cm: Safety and Effectiveness

🔍 **Clinical question:**
To compare the safety and effectiveness of image-guided thermal ablation (IGTA) for upper pole versus nonupper pole renal lesions ≤4 cm given the technical challenges of the former.

💡 **Key insight:**
Upper pole renal lesions ≤4 cm treated with image-guided thermal ablation showed comparable adverse event rates to nonupper pole lesions (Grade 3 [severe], 2.4% vs 1.3%, P > .99).

Primary effectiveness was 100% for upper pole lesions versus 97.3% for nonupper pole lesions (P = .54), with no difference in 3-year overall survival (92.9% vs 87.0%, P = .22) and local progression-free survival (90.0% vs 100.0%, P = .17).

Polar location (upper vs nonupper) and R.E.N.A.L./m.R.E.N.A.L. nephrometry scores had no association with adverse events or local progression.

👉 **Why it matters:**
Image-guided thermal ablation for upper pole renal lesions ≤ 4 cm demonstrated safety and oncologic outcomes comparable to non-upper pole lesions despite its increased technical complexity. Polar location alone should not exclude patients from consideration for image-guided thermal ablation.

**NEW IN JVIR:** Tumor-Absorbed Dose, Metabolic Response, and Survival after Yttrium-90 Radioembolization in Patients with Breast Cancer Liver Metastases

🔍 **Clinical Question:**
To evaluate the association between tumor-absorbed dose (TAD) relative to response and survival among patients with breast cancer liver metastasis (BCLM) treated with yttrium-90 (90Y) transarterial radioembolization (TARE).

💡 **Key insight:**
Overall survival was found to be significantly improved in responders compared with nonresponders among patients with breast cancer liver metastasis treated with yttrium-90 glass microspheres.

Tumor-absorbed dose showed a significant survival advantage above 145 Gy.

No significant difference was found in tumor-absorbed dose between responders and nonresponders.

👉 **Why it matters:**
Metabolic response predicts survival, dose thresholds matter, and higher dose alone does not guarantee response. These results highlight the need for personalized dosimetry in 90Y therapy for breast cancer liver metastases.

**NEW IN JVIR:** Transarterial Microembolization Therapy for Chronic First Metatarsophalangeal Joint Pain

🔍 **Clinical Question:**
To evaluate the feasibility, safety, and preliminary effectiveness of transarterial microembolization (TAME) for refractory first metatarsophalangeal joint (MTPJ) pain in patients with inflammatory arthritis, gout, or osteoarthritis.

💡 **Key Insight:**
Transarterial microembolization (TAME) targets hypervascularity and pathological nerve ingrowth, key contributors to chronic pain, by selectively embolizing feeder arteries, thereby disrupting pain pathways and reducing inflammatory mediators.

TAME demonstrated significant reduction in pain and weekly analgesic use, establishing it as a safe and effective minimally invasive alternative for managing chronic metatarsophalangeal joint pain refractory to conventional treatments.

👉 **Why it matters:**
The favorable safety profile and effectiveness of TAME suggest potential applications in other small joint pathologies.
