2022-08-23 16:20:16 Yttrium-90 Radioembolization for Liver-Dominant Metastatic Prostate Cancer: A Case Series
https://www.jvir.org/article/S1051-0443(22)00981-2/fulltext?rss=yes

Transarterial radioembolization (TARE) with yttrium-90 glass microspheres is widely used to treat primary and secondary malignancies in the liver. However, the safety and efficacy of TARE in patients with liver-dominant metastatic castration-resistant prostate cancer (mCRPC) is unknown. A proof-of-concept, retrospective analysis of 7 consecutive patients with liver-dominant mCRPC who were treated with TARE was performed. The median overall survival was 27.2, 32.1, and 108.1 months from the time of TARE, the diagnosis of liver metastases, and initial cancer diagnosis, respectively. Open / Comment

https://www.jvir.org/article/S1051-0443(22)00980-0/fulltext?rss=yes

This prospective study evaluated the safety and effectiveness of percutaneous sclerotherapy in the treatment of secondary Budd-Chiari syndrome due to hepatic venous malformations (HVMs). Four patients (mean age, 40 years; 3 women) with 5 HVMs underwent 7 sessions of percutaneous sclerotherapy with a mixture of bleomycin and lipiodol. All patients had chronic Budd-Chiari syndrome, determined based on imaging findings, with the main symptom being abdominal discomfort and distention. On physical examination, 2 patients had ascites and the other 2 had an epigastric mass. Open / Comment

2022-08-23 16:17:18 Safety of Uterine Artery Embolization for Subserosal Pedunculated Fibroids: Sufficient Data or More Studies Are Needed?
https://www.jvir.org/article/S1051-0443(22)00936-8/fulltext?rss=yes

Pedunculated subserosal fibroids were initially considered a relative contraindication to treatment using uterine artery embolization (UAE), based on the concern that after embolization, fibroids may undergo torsion or detachment, resulting in sepsis or bowel injury that would require emergency surgery (1). However, some studies (2–4) suggested that it is possible to perform UAE without this type of adverse event in patients with the International Federation of Gynecology and Obstetrics type 7 fibroids.

To measure ablation-zone temperature and non-target-tissue temperature during radiofrequency ablation (RFA) in bone containing metal instrumentation versus no metal instrumentation (control group). Open / Comment

2022-06-23 16:35:34 Percutaneous Hemodialysis Fistula Creation
https://www.jvir.org/article/S1051-0443(22)01015-6/fulltext?rss=yes

Two devices have been recently introduced to European Union and North American clinical practice that allow for percutaneous creation of autogenous hemodialysis fistulas (pAVF). Although there are similarities between the devices, there are many differences. Adoption of either or both technologies by an interventionalist may be determined by the individual’s comfort with the device. Importantly, current and future outcomes will shape acceptance and use of these devices. This review focuses on the similarities and differences of each device, the procedures, published outcomes to date and their interpretation and other clinical considerations towards initiation of a successful pAVF program.
