CT-Guided Vertebral Injection Curbs Palmar Hyperhydrosis

Minimally invasive procedure may help control 'sweaty hands' condition

WEDNESDAY, Nov. 30 (HealthDay News) -- Percutaneous thoracic sympathectomy using multislice computed tomography (CT) fluoroscopy successfully controls primary palmar hyperhydrosis or the embarrassing "sweaty hands" condition, researchers reported this week at the annual meeting of the Radiological Society of North America in Chicago.

Hugues Brat, M.D., of Centre Hospitalier Hornu Frameries, Hornu, Belgium, and colleagues evaluated 50 patients aged 18 to 37 with primary palmar hyperhydrosis. The patients underwent bilateral percutaneous thoracic sympathectomy, resulting in 103 procedures under local anesthesia. The researchers targeted the third thoracic vertebra, and used volumetric multislice CT fluoroscopy to guide a needle.

Immediate interruption of sweating was seen in 47 patients and 97 procedures. Three patients had a successful second procedure after an unsatisfactory one-sided result. Despite minor problems, there were no significant complications, the researchers report.

"Percutaneous thoracic sympathectomy using CT fluoroscopy for needle guidance and procedure management is a minimally invasive and efficient treatment for primary palmar hyperhydrosis," the authors write.
