Learn how to cross complete
venous occlusions with the Sniper Technique
This four-part educational series, equips endovascular interventionalists with advanced techniques for successful venous recanalization. Review all facets of the Sniper Technique, from pre-procedural planning to post-operative care, to facilitate safe and effective recanalization of even the most complex central venous occlusions (CVOs) and iliac vein obstructions.
Part 1: Patient Selection and Pre-Procedural Planning
Review critical anatomy and imaging when planning for the Sniper Technique. Explore advanced imaging techniques that can be implemented to enhance procedural efficiency and safety.
Part 2: Tools and Room Preparation
Review tools, equipment, and room setup to facilitate a successful procedure.
Part 3: Recanalization of Challenging Central Venous Occlusions (CVOs)
Explore the step-by-step technique for radiofrequency (RF)-assisted crossing of CVOs with the PowerWire® RF Guidewire (“RF Wire”).
Part 4: Addressing Complex Lower Extremity Occlusions
Review advanced techniques when approaching challenging lower extremity venous occlusions for safe and effective intervention.
Part 1: Patient Selection and Pre-Procedural Planning
Part 2: Tools and Room Preparation
Part 3: Recanalization of Challenging Central Venous Occlusions (CVOs)
