The trainees receive specialized education and training by local educational modules, by website educational resources, or a combination of both that include: (1) vascular anatomy and physiology (AnatomyZone, 2015), (2) web-based HD vascular access educational modules endorsed by the Ontario Renal Network and available via secure websites at the institutional level, (3) basic ultrasound physics (Hoffman, Rumsey, & Nixon, 2008), (4) operation of the ultrasound equipment, and (5) hands-on clinical assessment and real-time cannulation in accesses of varied complexities.
This technology can be applied to TIPS procedures in patients with BCS and other complex TIPS cases, as it may help delimit the trajectory of the needle pass and optimally result in more efficient portal vein cannulation and decreased radiation dose.
Without this technique it would be impossible to achieve cannulation around 'corners' of a tortuous radial artery.

In many patients, palpating and cannulating the arteriovenous fistula is challenging; the use of VWING(TM) is demonstrated to improve cannulation success with fewer attempts, thereby improving the experience for patients and healthcare professionals and providing a safe alternative for establishing cannulatable fistulas," said Avi Kometz, Partner at Deerfield.
Insertion of these catheters follows the same principles of CVC insertion, with the right internal jugular vein being the preferred insertion site due to easier catheterization, a relatively straight path to the superior vena cava and right atrium, high rates of cannulation success, and low rates of central venous stenosis (3, 4).
