’No Sweat’ CT-Guided Injection Treats Embarrassing Hand Condition

30.11.2005


A minimally invasive procedure can permanently cure people who suffer from "sweaty hands," according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).



Computed tomography (CT) fluoroscopy allows precise needle guidance in the treatment of palmar hyperhidrosis, or sweaty hands, minimizing risk and discomfort to the patient.

"This CT-guided percutaneous technique is the most secure treatment today and stops sweating from the hands to the armpits with very little chance of recurrence," said the study’s lead author, Hugues Brat, M.D., head of the radiology department at Centre Hospitalier Hornu - Frameries, in Hornu, Belgium.


Up to three out of every 100 people in the United States faces social and professional discomfort due to sweaty hands. The condition is caused by an overactivity of the sympathetic nervous system. Previously, the only known permanent treatments for sweaty hands were thoracic conventional or endoscopic surgical sympathectomies requiring general or local anesthesia. Both procedures are secure but can produce serious complications, ranging from bleeding and collapsed lung to partial paralysis and Horner syndrome, which affects movement of the eyelid.

Minimally invasive treatments are available which effectively treat sweaty hands with varying degrees of effectiveness, cost and risk to the patient. Some physicians offer local Botox injections, which are efficient but are painful and expensive and only last six months.

Percutaneous sympathectomy with CT fluoroscopy is a 20-minute procedure requiring no anesthesia, with no risk of nerve damage or bleeding and only minimal risk of Horner syndrome. Most patients require a single treatment for each side. As with surgical sympathectomy, there is an unpredictable but rare risk of compensatory sweating at the level of the chest.

For the procedure, interventional radiologists make a single needle puncture through the upper back and, using CT guidance, inject a phenol-based medication that interrupts the nerve tracts and nodes that transmit signals to the sweat glands. "This is the most precise and effective treatment of palmar hyperhidrosis available," Dr. Brat said.

For the study, Dr. Brat and colleagues performed CT-guided percutaneous thoracic sympathectomy on 50 consecutive men and women with palmar hyperhidrosis. The patients ranged in age from 18 to 37.

In all cases, multi-slice CT fluoroscopy enabled perfect needle guidance. Immediate successful results were observed in 47 patients (94 percent). Three patients underwent a successful second treatment. No significant complications were observed. Sixteen patients experienced minor complications including chest pain and thoracic discomfort, which resolved within a few hours.

The procedure, which can also be used to treat sweaty feet, is less expensive than open or endoscopic surgery and is often covered by insurance.

Dr. Brat cautioned, however, that the treatment is not for everyone. "If you suffer from this condition, it should significantly impair your normal life before you consider this type of treatment," he said. "Although sympathectomy is very effective, it is permanent. You must strike a balance between improvement of your quality of life with this or any other procedure and the potential risks and side effects of treatment."

Dr. Brat advises patients to discuss the risks and benefits with their physicians before undertaking any treatment plan.

Dr. Brat’s co-author is Tarik Bouziane, M.D.

Im Focus: Optical Nanoscope Allows Imaging of Quantum Dots

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
