Central Vein Stenosis Case Study

Chameleon™ PTA balloon catheter

Review how physicians use the Chameleon™ PTA balloon catheter for targeted imaging paired with direct angioplasty to address central venous (CV) stenosis.

Addressing imaging and accessibility for central venous stenosis

Direct stenosis imaging and inflation

Centrally located venous stenosis can offer access and imaging challenges. The Chameleon™ PTA balloon catheter enables both angioplasty and targeted contrast injection – with the ability to immediately image before and after inflation.

Case review of central vein stenosis

With Ari Kramer, M.D.

Experienced review of case steps for targeted diagnostic venogram, with immediate balloon inflation directly followed by reimaging for lesion treatment assessment.

Procedural approach for central vein stenosis​

Combined angioplasty and imaging step-by-step technique review​

1. High grade stenosis of the left innominate vein, with pronounced collateral filling

  • Ultrasound-guided micropuncture access is achieved
  • Initial fistulogram can be performed through the micropuncture sheath
  • Advancing the desired 0.035-inch working wire centrally, the micropuncture sheath is removed
  • The Chameleon™ PTA balloon catheter is directed to the central lesion

2. Angioplasty performed using the Chameleon PTA balloon catheter

  • Balloon angioplasty is performed
  • The balloon is then deflated and pulled back from the lesion (over the wire, maintaining wire access)

3. Immediate post-angioplasty imaging using the integrated third port confirms proper disruption

  • Contrast venography is performed through the Chameleon™ PTA balloon catheter injection port
  • Angioplasty results are immediately visualized

Comparing the Chameleon™ PTA balloon catheter with standard PTA balloon catheter use

Review how the Chameleon™ PTA balloon catheter compares to traditional PTA balloon catheters for central venous and cephalic arch stenosis procedures. See comparison study performance data from the Journal of Vascular Access.
