Percutaneous chemical dorsal sympathectomy for hyperhidrosis

Area of Science:

• Medical procedures
• Surgical interventions
• Neurology

Background:

• Palmar hyperhidrosis presents significant challenges, impacting daily activities and causing psychosocial distress.
• Existing treatments for severe palmar hyperhidrosis are often insufficient.
• A novel approach is needed to effectively manage medically refractory cases.

Purpose of the Study:

• To evaluate the safety and efficacy of a new chemical ablation technique.
• To target D2 and D3 dorsal sympathetic ganglia for palmar hyperhidrosis control.
• To assess the outcomes of chemical sympathectomy for refractory cases.

Main Methods:

• A cohort of 30 patients with refractory palmar hyperhidrosis was studied.
• Percutaneous chemical sympathectomy utilized absolute alcohol (97%) to ablate D2 and D3 sympathetic ganglia.
• Patients underwent follow-up at 1 week, 1 month, 3 months, and 1 year post-procedure.

Main Results:

• Complete cessation of palmar hyperhidrosis was achieved in 90% (27/30) of patients at the 1-year mark.
• The procedure demonstrated a high success rate in alleviating excessive palm sweating.
• No serious perioperative or postoperative complications were reported.

Conclusions:

• Percutaneous chemical dorsal sympathectomy is a safe and effective treatment option.
• The procedure offers a straightforward method for managing palmar hyperhidrosis.
• This technique provides a viable solution for patients with medically refractory symptoms.
