Computed tomography guided thoracic sympatholysis for palmar hyperhidrosis

Sixteen patients (mean age 26.3 years; range 18-38) with palmar hyperhidrosis underwent 29 sympatholyses after unsuccessful medical, and in 8 ionophoresis, treatments. Sympatholysis was performed under local anesthesia with computed tomographic guidance. After opacification of the injection site at T3 with Iopamiron 200, phenolization was performed with 10 ml 6% phenol.

Good immediate results evaluated on the basis of venous dilatation, and dryness and warmth of the skin were obtained in 23 cases (80%). There were 6 immediately unsuccessful procedures in 4 patients. At 20 months, good results, assessed on the basis of objective criteria and subjective patient self-evaluation were obtained in 22 cases (75% including immediate failures). Computed tomography guided thoracic sympatholysis performed under local anesthesia is an effective treatment for palmar hyperhidrosis. Morbidity is low and hospital stay is short.

Our findings suggest that thoracic sympatholysis should be indicated as the first intention procedure when surgery is required in patients with palmar hyperhidrosis.
