ATLANTA (Ivanhoe Newswire/WTVM) – Cryoablation therapy has long been used to treat pain in cancer patients. But now, a doctor at Emory University is trying it out on other types of nerve pain, and what he's finding could bring pain relief to millions of amputees suffering from phantom limb pain. We take a look at one of the first patients to try this experimental procedure.
Training the next generation of firefighters requires experience and discipline and Gene Hull has both.
What he doesn't have is both arms. He lost the right one to cancer 10 years ago.
Hull says, "I thought about my family and how it was going to affect them. I thought about my job and how it was going to affect that."
But he didn't fully consider how it would affect his quality of life. He knew is arm was gone, but his brain would sometimes forget.
"I'd be sitting in my office or teaching a class and I'd get those pains and you can imagine what it's like getting hit by a cattle prod; that's the only thing I can equate it to," Hull explains.
J. David Prologo, MD, Interventional Radiologist at Emory School of Medicine in Atlanta says, "Many of the nerves that we know are responsible for carrying pain symptoms are not accessible to pain doctors."
But those nerves are accessible to interventional radiologists like Dr. Prologo who uses 'image guiding' to pinpoint the exact nerve that's causing the pain. He then uses cryoablation to freeze it.
Dr. Prologo says, "So basically you got a nerve that's sending pain signals, pain signals, pain signals and after you freeze it and then thaw it, those pain signals stop."
Hull says, "I still get those pains a little bit, but they're nowhere near what they used to be. Now they're just a mild discomfort." And a mild discomfort is a welcome relief from the severe pain gene felt in his phantom limb for almost 10 years.
Dr. Prologo believes military veterans who experience phantom pain after losing a limb in combat are excellent candidates for cryoablation therapy. He is applying for a grant from the Department of Defense to fund a clinical trial at several locations around the country.
