[Evaluation of the efficacy of CT guided thoracic sympatholysis to treat palmar hyperhidrosis].

PURPOSE AND METHOD: Palmar hyperhidrosis is a pathological condition characterized by overperspiration caused by any stress or emotion. We have evaluated the results of 101 CT guided sympatholysis procedures performed on 50 patients suffering from primary palmar hyperhydrosis.

RESULTS: Mean follow up was 50 Months (6 Months to 8 Years) for 87 procedures with immediate good results in 46 patients. Using actuarial analysis, 62% of patients had persistent good results after 50 Months. Complications included one case of small pneumothorax requiring no treatment and one case of vagal syndrome. Pain or thoracic discomfort was reported by 14 patients and was relieved by aspirin within 24 hours. Six patients developed a Horner's syndrome that resolved within a few weeks and six other patients developed moderate compensatory overperspiration over the face, thorax or contralateral arm.

CONCLUSION: Based on our results, CT guided sympatholysis provides results similar to endoscopic thoracic sympathectomy and is associated with fewer risks.
