OBJECTIVEChronic ventriculomegaly in the absence of raised intracranial pressure (ICP) is a known entity in adult hydrocephalus practice. The natural history and indication for treatment is, however, poorly defined. A highly heterogeneous group, some adults with ventriculomegaly are asymptomatic, while others have life-threatening deteriorations. The authors hypothesized that the various presentations can be subtyped and represent different stages of decompensation. A cluster analysis was performed on a cohort of patients with chronic ventriculomegaly with the aim of elucidating typical clinical characteristics and outcomes in chronic ventriculomegaly in adults...

Digital subtraction angiography (DSA) is a technique used in interventional radiology for the diagnosis of vascular cerebral conditions. Central retinal artery occlusion (CRAO) is a complication of endovascular procedures that involve atherosclerotic plaque removal with subsequent embolisation. The case is presented on a patient who noticed a sudden vision loss during a DSA. Funduscopy showed retinal pallor and a cherry red spot. The angiography showed a structure suggesting the presence of an embolus in the central retinal artery...

Background: There has been significant improvement in understanding the etiology and management of Budd-Chiari Syndrome (BCS). Patients with chronic or acute-on-chronic BCS need radiological interventions in the form of angioplasty, hepatic vein/inferior vena cava stenting or Transjugular Intrahepatic Portosystemic Shunt (TIPS). Data regarding the long term follow up of patients undergoing TIPS is limited. We thus prospectively followed-up BCS patients who underwent TIPS at our center...

With the ongoing changes in graduate medical education, emphasis has been placed on simulation models to increase clinical exposure and optimize learning. In specific, high-fidelity simulation presents as a potential option for procedural-skill development in interventional radiology. With improved haptic, visual, and tactile dynamics, high-fidelity endovascular simulators have gained increasing support from trainees and certified interventionalists alike. The 2 most common high-fidelity endovascular simulators utilized today are the Procedicus VIST and ANGIO Mentor, which contain notable differences in technical features, case availability, and cost...

The current model for medical education is based on the Master-Apprentice model which was adopted into practice over a century ago. Since then, there have been many changes in healthcare and the environment in which trainees learn, practice and become proficient in procedural and critical thinking skills. The current model for medical education has however, not changed considerably in this time frame, resulting in significant limitations to trainee education. Simulator-based training is a technique which can minimize the limitations of the apprenticeship model by mitigating the effect of time constraints, increased emphasis on patient safety and satisfaction and nonstandardization of Interventional Radiology (IR) curricula...

Efficient teamwork and communication is critical for the delivery of safe and high quality patient care. Studies have shown that medical errors can occur as a result of poor communication. Simulation scenarios can help improve communication and teamwork, therefore decreasing errors and improving team morale. Simulation is best employed through a multidisciplinary approach, including all members of the team involved in the patient's care. Team simulation can be difficult to plan and execute, therefore we will review the steps to planning an effective multidisciplinary team simulation, as well as the barriers to overcome when implementing these programs...

Interventional Radiology (IR) incorporates a unique set of technical skills such as ultrasound-guided needle placement, inferior vena cava filter placement, and wire/catheter exchange, which are not easily attained in other aspects of medical training. Simple, low cost models can allow medical students and residents to attain these skills in a low risk setting. These simulated tasks will ultimately combine to improve preparedness of trainees during patient procedures allowing them to advance more quickly through the training paradigm without patient risk...

Advanced practice registered nurses, such as Nurse Practitioners (NPs), can be found working in a variety of settings. Niche practices, such as Interventional Radiology, are highly specialized areas and are often specialties in which few NPs get to orient through during their graduate nursing program clinical rotations. For the NP transitioning into an Interventional Radiology practice, formal on-the-job orientation and training can assist in gaining specialty-based knowledge and competencies in performing interventional procedures...

With the advances in affordable three-dimensional (3D) printing technology, 3D reconstruction and patient-specific 3D printed models are establishing a crucial role in the field of medicine for both educational purposes and procedural planning. 3D printed models provide physicians with increased 3D perception and tactile feedback, and enable a team-based approach to operational planning. However, performing an effective 3D reconstruction requires an in-depth understanding of the software features to accurately segment and reconstruct the human anatomy of interest from preacquired image data from multiple modalities such as computer tomography, 3D angiography and magnetic resonance imaging, and the different 3D printers/materials available in the market today...
