Purpose
This exhibit is designed to review the PowerWire Radiofrequency Guidewire and its use in the treatment of chronic venous occlusions.
Materials & Methods
Chronic venous occlusions can occur in the setting of venous thromboembolic disease as well as in patients requiring hemodialysis and prolonged venous access. This condition can be associated with significant morbidity and in some cases, particularly in patients with SVC Syndrome, can potentially be life threatening. Endovascular treatment options can be used in these patients but this is dependent on the ability of an interventionalist to cross the occlusion with a guidewire. This may occur in almost 25% of patients using standard catheter and guidewire techniques. The use of the PowerWire is a potential option for patients in whom standard techniques fail to result in guidewire passage across a chronic occlusion as a prelude to endovascular stent placement.
Results
This teaching exhibit will review the construction of this wire and the mechanism by which it can be used in the treatment of chronic venous occlusions. The available literature will be reviewed to highlight the indications for treatment, the clinical outcomes that have been demonstrated, and the potential complications that may be associated with it use. Case studies will be provided to demonstrate the potential success that can result in this use of the PowerWire in patients with chronic venous thromboembolic disease, occluded TIPS stents, thrombosed dialysis access, and SVC Syndrome.
Conclusions
The use of the PowerWire Radiofrequency Guidewire has significantly changed the approach to treating patients with chronic venous occlusions. Standard catheter and guidewire techniques are limited in their ability to treat all patients with this condition. The PowerWire has expanded the number of patients that can be treated by Interventional Radiology. However, the use of this wire must be accompanied by an understanding of the guidewire itself in addition to how the product should be used and its potential outcomes and complications.
