About the Procedure
Angioplasty and cryoplasty are performed basically the same way: A small incision is made in the main artery of the leg. A catheter is threaded into the clogged artery, where a balloon is inflated to compress the blockage and reopen the vessel. Once the vessel is opened, the balloon is deflated and removed.
How is Cryoplasty Different?
In traditional angioplasty, the balloon is inflated with saline solution. In cryoplasty, the balloon is inflated with nitrous oxide. The nitrous oxide cools to -10 degrees Celsius, which freezes the plaque.
