OBJECTIVES: To retrospectively evaluate sclerotherapy using consecutive polidocanol and bleomycin foam (CPBF) on large untreated venous malformations (VM) and/or those resistant to prior treatment. METHODS: This retrospective study included all patients treated by CPBF for untreated VM larger than 10 mL and/or refractory to treatment between May 2016 and October 2019. Baseline and follow-up VM volumes were measured on fat-suppressed T2-weighted MRI. Outcome was evaluated on post-procedure MRI volumetry and by a retrospective survey assessing clinical response and adverse events...

PURPOSE: To improve radiopacity of radiolucent absorbable poly-p-dioxanone (PPDO) inferior vena cava filters (IVCFs) and demostrate its efficacy in clot-trapping ability. MATERIALS AND METHODS: We incorporated tungsten NPs (WNPs), along with polyhydroxybutyrate (PHB), polycaprolactone (PCL), and polyvinylpyrrolidone (PVP) polymers to increase the surface adsorption of WNPs. We compared the physicochemical, in vitro, and in vivo imaging properties of PPDO-IVCFs with WNPs with single-polymer PHB (W-P), and WNPs with polymer blends consisting of PHB, PCL, and PVP (W-PB)...

PURPOSE: To study HCC patient experiences contributing to treatment discrepancy in the U.S. METHODS: Using NCI's SEER data, Medicare (2002-2015) beneficiaries with HCC who completed a Consumer Assessment of Healthcare Providers and Systems (CAHPS) Survey were included. Six CAHPS items (3 global scores: Global Care Rating [GCR], Primary Doctor Rating [PDR], Specialist Rating [SR]; 3 composite scores: Getting Needed Care [GNC], Getting Care Quickly [GCQ] and Doctor Communication [DC]) assessed patient experience...

PURPOSE: To develop a reproducible in vitro model simulating central venous catheter (CVC) exchange with high potential for air embolization and test the hypothesis that a closed catheter clamp over Glidewire exchange technique will significantly reduce the volume of air introduced during CVC exchange. MATERIALS & METHODS: The model consisted of a 16 Fr valved sheath, 240 mL container, and pressure transducer submerged in water in a 1200 mL suction canister system...

OBJECTIVES: To identify the appropriately sized imaging-visible embolics with balanced safety and efficacy for bariatric arterial embolization (BAE) in a preclinical model. MATERIALS AND METHODS: Twenty-seven pigs were divided into three cohorts. In cohort I, 16 pigs were randomized to receive either (n=4 each) 40-100 μm in one or two fundal arteries, or 70-340 μm radiopaque microspheres in two fundal arteries, or saline. In cohort II, three pigs underwent renal arterial embolization with either custom made 100-200 μm, 200-250 μm, 200-300 μm, 300-400 μm radiopaque microspheres, or Bead Block 300-500 μm with microsphere distribution assessed histologically...

PURPOSE: To evaluate the feasibility of the glue-in-plug (GIP) technique using n-butyl-2-cyanoacrylate‒Lipiodol (NL)‒iopamidol (NLI) for short-segment embolization in swine. MATERIALS AND METHODS: The renal arteries, left external iliac artery, subclavian arteries, and common carotid arteries were each embolized in four swine using the GIP technique under general anesthesia. First, a type I Amplatzer vascular plug (AVP) (1‒2 times the target vessel diameter) was deployed in the target artery...

PURPOSE: To examine the effect of end-stage renal disease (ESRD) on the likelihood of major adverse limb events (MALE) in patients with Rutherford 4-6 critical limb ischemia (CLI) undergoing percutaneous vascular intervention (PVI). MATERIALS AND METHODS: Two contemporaneous cohorts of patients undergoing PVI for symptomatic CLI from 2012 to 2022, differing in ESRD status, were matched using propensity score methods. This database identified 628 patients undergoing 1297 lower extremity revascularization procedures; propensity score matching yielded 147 patients (180 limbs, 90 limbs in each group)...

This retrospective study evaluated the feasibility and safety of percutaneous computed tomography (CT)-guided bone biopsies in cancer patients using a patient-mounted robotic system with steering capabilities. The study included 39 patients (17 female, 22 male; median age 65.5 years, interquartile range: 54.8-71). Forty biopsies were performed in the pelvis, spine, ribs, shoulder, femur, and sternum. The technical success rate was 100%, and the median trajectory length was 55.9 mm (47.1-73.6). Intermediate checkpoints were used in eight biopsies...

PURPOSE: To quantify perfusion changes during Genicular Artery Embolization (GAE) with the qualitatively described "pruning" technique using parametric analysis. METHODS: A total of 12 patients underwent unilateral GAE for a total of 36 vessels embolized. Among 34/36 vessels embolized, regions of interest (ROIs) were placed on parent vessels (PV) and hyperemic target vessels (TV) before and after GAE. For each ROI: peak-intensity (PI), time to arrival (TTA), and area under the curve (AUC) was computed and compared between PV&TV...

PURPOSE: To evaluate safety and efficacy of prostatic artery embolization (PAE) using polyethylene glycol (PEG) microspheres in patients with moderate to severe benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A single center, prospective study of 30 patients undergoing PAE from August 2020 to December 2021 using PEG 400μm microspheres was conduct. Patient evaluation using International Prostate Symptom Score (IPSS), quality-of-life (QoL) score, prostate-specific antigen (PSA), peak urinary flow rate (Qmax), postvoid residual volume (PVR) and prostate volume (PV) at baseline, 3 and 12 months after PAE were obtained...

PURPOSE: To determine overall survival, best response and toxicities in HCC patients previously treated with chemoembolization (TACE+) treated with resin 90Y transarterial radioembolization (TARE) compared to TACE-naïve (T-N) participants. MATERIALS AND METHODS: In this prospective, observational study, 262 adult participants with HCC were TACE+ (n=93, 35%) or T-N (n=169, 65%) at 36 centers in the United States. Overall survival (OS) was assessed using Kaplan-Meier analysis from the date of TARE...

PURPOSE: The study aimed to evaluate the efficacy of tract embolization using a gelatin sponge slurry in percutaneous ultrasound (US)-guided liver biopsy. MATERIALS AND METHODS: Among the 543 patients who underwent percutaneous US-guided liver biopsies between September 2018 and August 2021, 338 patients who did not undergo tract embolization and 105 who underwent tract embolization were included in the analysis. All procedures were conducted with 18G co-axial core biopsy needles...

OBJECTIVE: To assess the reported safety and effectiveness of sclerotherapy for the treatment of non-parasitic splenic cysts through a systematic review and metanalysis. MATERIALS AND METHODS: A systematic search of PubMed Medline, Embase, Web of Science and the Cochrane library through July 2023 was performed. Studies including at least 5 patients reporting percutaneous sclerotherapy of non-parasitic splenic cysts, initial and post-treatment cyst size, clinical symptoms as well as adverse events (AE) and recurrence rates were included...
