BACKGROUND: Palmar hyperhidrosis is a common functional disorder in the Asians. Currently, transthoracic endoscopic sympathectomy (TES) is considered to be the treatment of choice for this entity because of its high initial success rate and minimal morbidity. However, primary failure and recurrence of hyperhidrosis occurred in some patients, even with a very low incidence. We present our experience in the treatment of primary failure and recurrence of hyperhidrosis after TES by means of percutaneous computer tomography (CT) guided ethanol thoracic sympathectomy. METHODS: From July 1999 to July 2001, 11 patients (2 males and 9 females with a mean age of 25.9 years, range: 19-44 years) of this subgroup underwent percutaneous CT-guided chemical thoracic sympathectomy. Failure of the first sympathectomy was caused by severe pleural adhesion (from the previous operative findings) in 7 patients. The remaining 4 patients were recurrent palmar hyperhidrosis. All patients underwent unilateral procedures (3 on the right and 8 on the left). RESULTS: All patients were followed for at least 2 years after the treatment. Needle puncture was possible without difficulty in all patients. All patients had satisfactory results with minimal complication. No recurrence was noted at follow-up. CONCLUSION: In summary, percutaneous CT-guided ethanol thoracic sympathectomy could be an easy, safe, and alternative strategy to treat patients with palmar hyperhidrosis after failure or recurrence after TES.
