Purpose
Radiation protection in fluoroscopy guided procedures is traditionally based on fluoroscopy equipment, but generally does not include tailored means of dose management. We believe that the disposables also have to be designed for optimal dose efficiency and procedure safety. Chameleon™ is an FDA approved, angioplasty balloon catheter that allows vessel imaging by injecting contrast through the catheter, whether the balloon is inflated or deflated, while maintaining wire position. Our aim was evaluation of Chameleon™ PTA balloon catheter performance and it's dose efficiency on an animal model.
Materials & Methods
We performed pre-clinical evaluation of Chameleon™ PTA balloon catheter and angioplasty procedure with a standard balloon a on an animal model of AV graft placed between the femoral artery and femoral vein of a pig. The procedures included angioplasty of the venous and arterial anastomosis, post angioplasty imaging of the treated area and reflux angiography for evaluation of the arterial anastomosis. Each type of procedure was performed 3 times by each of 3 experienced interventional radiologists. We measured and recorded procedure and fluoroscopy time with both approaches.
Results
Procedure and fluoroscopy time was reduced by reducing number of catheter and guide wire exchanges. Average procedure time with standard angioplasty versus Chameleon™ was 101 seconds versus 16.5 seconds which represents an 89% reduction. Average fluoroscopy time with standard angioplasty versus Chameleon was 16 seconds versus 6.6 seconds which represents a 60% reduction in fluoroscopy time. The differences were statistically significant (p<0.05).
Conclusions
Proximal injection angioplasty balloon catheter reduces catheter exchanges and guide wire removals and eliminates the need for manual compression reflux angiography. This technique seamlessly reduces patient and personnel radiation exposure by reducing fluoroscopy time.
