PURPOSE: To determine the efficacy and safety of cryoablation in pediatric and young adult patients with desmoid tumors (DTs) retrospectively over a 10-year period. MATERIALS AND METHODS: Twenty-one patients (age 2-22 years; median 14 years), with 21 desmoid tumors, underwent a total of 34 percutaneous cryoablation procedures between August 2013 and August 2023. All patients, excluding two, had surgical resection, chemotherapy, or a combination of these therapies with failed or suboptimal response...

PURPOSE: To evaluate gyroscope-assisted CT-guided needle puncture (GAP) compared to free hand puncture (FHP) in a phantom. MATERIAL AND METHODS: A simple, low-cost gyroscope was equipped with a magnetic rail to attach it to common puncture needles. 18 radiologists with different levels of training and experience in CT-guided punctures first punctured three targets in free hand technique in a special biopsy phantom with different difficulty levels of the puncture path (T1: not angulated, needle path 7...

INTRODUCTION: Literature shows differences in pain experiences between sexes. The exact influence of thermal liver ablation on experienced pain is still not well-known. This study aims to investigate the maximum pain intensity at the recovery between men and women after percutaneous thermal liver ablation. METHODS: Patients treated with percutaneous thermal liver ablation (radiofrequency or microwave ablation) in Maastricht University Medical Center + between 2018 and 2022 for primary or secondary liver tumors were included retrospectively...

PURPOSE: To describe clinical outcomes among patients with benign prostatic hyperplasia (BPH) 24 months following prostatic artery embolization (PAE). MATERIALS AND METHODS: This was an international, multicenter, prospective trial of males with BPH with lower urinary tract symptoms (LUTS) or acute urinary retention (AUR) treated with PAE. The primary outcome was the 12 month change in the International Prostate Symptom Score (IPSS) for patients referred for bothersome LUTS, or urinary catheter independence for patients treated for AUR...

PURPOSE: Electrochemotherapy, clinically established for treating (sub)cutaneous tumors, has been standardized in the framework of the European Standard Operating Procedure on Electrochemotherapy (ESOPE). Due to common side effects of chemotherapeutic drugs, recent advances focus on non-cytotoxic agents, like calcium, to induce cell death (calcium electroporation). Therefore, this study aims to determine the efficacy of electrochemotherapy with bleomycin or cisplatin, or calcium electroporation on human hepatocellular carcinoma cells (HepG2) in vitro using the ESOPE protocol...

PURPOSE: Currently, significant medical practice variation exists in thermal ablation (TA) of malignant liver tumors with associated differences in outcomes. The IMaging and Advanced Guidance for workflow optimization in Interventional Oncology (IMAGIO) consortium aims to integrate interventional oncology into the standard clinical pathway for cancer treatment in Europe by 2030, by development of a standardized low-complex-high-precision workflow for TA of malignant liver tumors. This study was conducted at the start of the IMAGIO project with the aim to explore the current state and future role of modern technology in TA of malignant liver tumors...

INTRODUCTION: Deep venous stent placement has developed into a primary treatment modality for venous obstruction in recent decades. Reported rates of complications are low in the literature and are based mainly on case reports and single-centre cohorts. Interventionalists performing these procedures must be aware of the occurrence of complications associated with stent placement to counsel patients adequately and promote avoidance through optimal procedural approach. This study aims to determine the incidence of serious complications associated with iliocaval and iliofemoral stent placement in a cohort of patients from 3 major tertiary deep venous referral centres...

OBJECTIVE: To describe and study retrospectively the combination of elastic nails and cementoplasty to stabilize pathological fractures in the upper limb and present the results on pain and mobility. MATERIALS AND METHODS: Between January 2022 and April 2024, six patients with a median age of 65 were treated with elastic nailing and cement injection. Pathological fractures were located in the clavicle (n = 3), humerus (n = 1) and radius (n = 2)...

PURPOSE: To investigate the preliminary treatment outcomes of transcatheter arterial embolization (TAE) for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). MATERIALS AND METHODS: This retrospective study included patients with refractory CP/CPPS who underwent TAE between April 2022 and February 2023. All patients had persistent pelvic pain for at least 3 months, a total score of at least 15 on the NIH-Chronic Prostatitis Symptom Index (NIH-CPSI), and lacked evidence of infection...

PURPOSE: Peripheral arterial calcification is an important predictor of outcomes after both conservative and endovascular treatment. Digital subtraction angiography (DSA)-based calcification scores are limited by low sensitivity and inter-observer agreement. The Peripheral Arterial Calcium Scoring System (PACSS) assesses the severity of target lesion calcification. The newly introduced modified PACSS (mPACSS) also evaluates target vessel calcification. This study aimed to assess the inter- and intra-observer reliability of PACSS and mPACSS on computed tomography angiography (CTA) in (infra)popliteal endovascular interventions...

PURPOSE: Transarterial radioembolization (TARE) has emerged as a promising therapeutic approach for unresectable intrahepatic cholangiocarcinoma (ICCA). We updated our previous meta-analysis with meta-regression to explore the efficacy of TARE in the context of ICCA. METHODS: We searched PubMed and Scopus for studies published up to September 1, 2023. The primary outcome was overall survival. Secondary outcomes were tumor overall response rate, severe adverse events, and downstaging to surgery...

PURPOSE: To evaluate Vessel Tracking software for determining the prostatic arteries feeding the prostate gland during prostatic artery embolization (PAE) using Conebeam-CT (CBCT). MATERIALS AND METHODS: EmboGuide is a software developed to assist interventional radiologists in performing embolization of hypervascular tumors in the liver. In this study, a single-center retrospective image collection of 120 intraprocedural CBCT of 60 patients with benign prostatic hyperplasia treated using PAE between May 2017 and January 2019 was evaluated...

PURPOSE: Proton therapy is highly effective for liver malignancies, and to increase its accuracy, placement of fiducial markers in the liver is preferred. We retrospectively evaluated the safety and feasibility of CT-guided fiducial marker implantation using ultra-fine 25-gauge needles before proton therapy for liver malignancies. MATERIALS AND METHODS: Between May 2016 and April 2021, 334 cases were investigated. All of procedures were performed without anesthesia...

PURPOSE: This study aims to evaluate the safety and effectiveness of genicular artery embolization (GAE) using lipiodol in comparison to imipenem/cilastatin (IPM-CS). MATERIALS AND METHODS: This retrospective study screened patients who underwent GAE between January 2022 and February 2023 for inclusion. Clinical outcomes were assessed at 1, 3, and 6 months post-procedure using the Visual Analog Scale (VAS) for pain and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for pain, stiffness, functional capacity, and total scores...

PURPOSE: To evaluate the effect of being under time pressure on procedural performance using hand motion analysis. MATERIALS AND METHODS: Eight radiology trainees performed central venous access on a phantom while recording video and hand motion data using an electromagnetic motion tracker. Each trainee performed the procedure six times: the first three trials without any prompts (control), while for the next three, they were asked to perform the task as fast as possible (time pressure)...
