Role of virtual reality simulation in teaching and assessing technical skills in endovascular intervention.
Training in endovascular intervention ultimately aims to produce interventionalists who demonstrate competence in technical skills. Herein, the authors investigate the rationale for simulation-based training by providing an overview of the psychological theories underpinning acquisition of technical skills, training and assessment history, recent advances in simulation technology, and a critical appraisal of their role in training and assessment in endovascular intervention. Simulators have potential for training and assessment and promise solution to many shortcomings of traditional 'apprenticeship' training models. Before inclusion into the curriculum, further work is needed regarding fidelity, validity, reliability, and design of simulators to ensure accurate transfer of acquired endovascular skills from simulator to patient.

High-risk retrieval of adherent and chronically implanted IVC filters: techniques for removal and management of thrombotic complications.
To evaluate the safety and efficacy of aggressive techniques for retrieving adherent and chronically implanted inferior vena cava (IVC) filters. ⋯ Alternative techniques can be used to retrieve adherent IVC filters implanted for up to 3-5 years. Although caval thrombosis was an observed complication, protocol modifications appeared to reduce this risk.

Fluoroscopically guided percutaneous jejunostomy with use of a 21-gauge needle: a prospective study in 51 patients.
To assess the safety and clinical efficacy of fluoroscopically guided percutaneous jejunostomy with use of a 21-gauge needle and a single anchor technique in 51 patients. ⋯ Fluoroscopically guided percutaneous jejunostomy with use of a 21-gauge needle and the single anchor technique seems to be safe and effective, with high technical success and low complication rates.

Review Meta AnalysisCatheter-directed therapy for the treatment of massive pulmonary embolism: systematic review and meta-analysis of modern techniques.
Systemic thrombolysis for the treatment of acute pulmonary embolism (PE) carries an estimated 20% risk of major hemorrhage, including a 3%-5% risk of hemorrhagic stroke. The authors used evidence-based methods to evaluate the safety and effectiveness of modern catheter-directed therapy (CDT) as an alternative treatment for massive PE. ⋯ Modern CDT is a relatively safe and effective treatment for acute massive PE. At experienced centers, CDT should be considered as a first-line treatment for patients with massive PE.

Multicenter StudyShort- and long-term retrievability of the Celect vena cava filter: results from a multi-institutional registry.
To evaluate retrievability of the Celect vena cava filter over time and to assess the safety of the retrieval procedure in a prospective multicenter registry. ⋯ Retrieval of the Celect filter was performed safely as long as 466 days after implantation.
