Cryoablation

Is anyone here performing cryoablation on a regular basis?

What conditions respond best?
Average duration of benefit?
What system are you using (Iovera etc)?
What are the advantages compared to thermal ablation in your opinion?

Very long time ago I acquired a cryoprobe gratis. The problem I remember is the probe was huge. Advantage is limited post procedure neuritis. Stopped using it as pulsed RF is technically much easier. Hopefully the cryoprobes are much smaller now.

I've used Iovera a few times. Works well for things where it doesn't really matter if you move a little like genicular nerves but the probe is pretty large and unbalanced (all the weight is in the handle). Doing something much more risky like intercostal nerve ablation wasn't fun because of that.

The rep mentioned that they are about to publish a study comparing cryoablation to RFA for lumbar facets, and that cryoablation came out on top. This is interesting if true (and if it's a good study) but the issue is that you can only do a single lesion at a time and it's like the tip of the cannula would move during the ablation.

Less frequent use of late because of worsening insurance coverage, but have done >1500 cases. Mostly knee, but have done shoulder, intercostal, genitofemoral/ilioinguinal and various nerves in residual limb pain many times.
All Iovera. 3 to 6 months if it works.

For me, the advantage is doing it in clinic, markedly cheaper than going to HOPD Center and much faster for me. U/s not fluoro is better for peripheral nerves including knee. Relatively less damage to the nerve, relatively lower risk, at least conceptually.

Not to mention the duration of relief is ~3 months, as opposed to 6-18 months with RF.

Why can’t you do rfa in clinic?

Need fluoro.
