Just finishing up, neurolysis and nerve ablation. We talked a little bit about this, but the goal is to permanently disrupt the axons and the myelin sheath. You can do it chemically with alcohol or phenol. But more and more people now are offering
radiofrequency ablation or cryoablation as a more precise way of performing these ablations. Radiofrequency ablation probably has the most data after alcohol and phenol. It's inexpensive and it has a long track record. Cryoablation is now being reported in the literature.
It's easy to see on CT as my colleagues have demonstrated. It's good in soft tissue tumors, but we still have very early data. Some people are actually looking at MR-guided focus ultrasound, very sexy, very expensive technology, very niche.
I don't really see that becoming a major player. I think it's really gonna be RFA and cryoablation,
review of the electrical conduction pathway here.
We're gonna, this is a slide that just shows how normal conduction would work initiated at the sinoatrial node on down. And then here the yellow color within these diagrams, shows the areas of the heart that are depolarized. And, of course, our patients who
have ended up at the electrophysiologist have some kind of disruption in this conduction. And so, when these patients, when and if these patients end up with a device and end up in radiology we need to have a basic understanding
So now we move from a potential case like this
where the patient has a large renal mass and a metastasis into their left femur, and that patient underwent a surgical resection here, replacement of that, a big operation for a patient with metastatic disease, now we take a similar kind of patient
with a left renal cell carcinoma and has two metastases, one in a rib and a small one in the acetabular region. And they undergo the nephrectomy and then ablation of these two areas. That may be the new model.
