Retrograde Technique Case Study
View how physicians use an integrated injection modality to perform combined angioplasty and targeted diagnostic imaging in retrograde fashion.
Addressing the complexities of angiogplasty in retrograde
For stenoses close to a fistula’s anastomosis, retrograde access from the venous side is required — performing “against the flow,” and often resulting in diluted imagery or multiple procedural steps and catheter exchanges.
By offering PTA with an integrated contrast injection option, the Chameleon™ PTA balloon catheter enables targeted diagnostic imaging immediately following angioplasty – with the ability for repeated angioplasty and imaging directly at the lesion site as needed.

Case review
High pressure PTA with moderate compliance in retrograde approach
- 57-year-old male
- End stage renal disease
- Multiple failed accesses to left arm
- Functioning right brachio-basilic fistula
Retrograde technique case study:
Contrast delivery in retrograde approach
- 80-year-old male
- AV fistula with anastomotic stenosis
- Poor flow in a brachiocephalic fistula
- Chameleon™ PTA balloon catheter 5 x 40 mm
Tight stenosis near anastomosis
Balloon inflation at AV anastomosis
Post-inflation, deflate and advance balloon over the wire beyond anastomosis
Maintaining wire position, inject contrast through Chameleon™ PTA balloon catheter to visualize area post treatment
Step-by-step retrograde case review with Dr. Ari Kramer
- Juxta-anastomotic fistula stenosis
- Narrowing at brachial artery and cephalic vein
- Retrograde approach to standard AV fistula
- Imaging of circuit while maintaining guidewire control in retrograde approach
Step 1
Once access is achieved, the Chameleon™ PTA balloon catheter is advanced to the treatment site and angioplasty is performed.
Step 2
The device is deflated and advanced to the arterial side.
Step 3
Finally, contrast is injected directly through the Chameleon™ PTA balloon catheter, enabling the assessment of angioplasty results.
