Indications • Palmarand axillaryhyperhydrosis • Facial flushing • Upper extremity ischemia • Chronic regional pain syndrome
Hyperhydrosis • Palmar, axillary, and plantar hyperhydrosis • Excessive sweating of the palms of the hands, axillae, and soles of the feet • Creates vocational, social, and medical impairments

Hyperhydrosis • Primary (idiopathic) • Secondary
Hyperhydrosis • Primary • Over-stimulation of sympathetic nervous system • Most common form • Unknown etiology • Localized • Palms • Axilla • Soles of feet • Scalp, face
Hyperhydrosis • Secondary • Hyperthyroidism, hypertension • Diabetes / pheochromocytoma • Menopause • Obesity • Drug use • Anti-depressants • Anti-emetics
Treatment of Primary Hyperhydrosis • Anti-perspirants • Iontophoresis • Botox • Systemic medications • Surgery • Axillary liposuction • Excision of axillary tissue • Sympathectomy
Treatment of Secondary Hyperhydrosis • Treatment of the underlying condition
Medical Treatments • Anti-persirants • Aluminum chloride (Drysol) • Glutaraldehyde, tannic acid, astringent
Medical Treatments • Iontophoresis / Drionics • Second line treatment • Palmar and plantar • Electric current (15 – 30 mA) • Immersion 20 minutes 2 – 3 times / week • 70% effective in mild Hyperhydrosis • Sweating returns after cessation of treatment
Medical Treatments • Anticholinergics • Robinul 1 – 4 mg po TID • Dry mouth, urinary retention, constipation, dizziness • Oxybutynin (Ditropan) 10 – 20 mg po daily • Dry mouth, dizziness • Rebound excessive sweating
Medical Treatments • Alpha agonists • Clonidine (Catapres) 0.1 to 0.3 daily • Dry mouth, dizziness, sleepiness, fatigue • Less effect over time • Rebound sweating • Beta blockers • Inderal 10 mg potid or prn

Chronic Regional Pain Syndrome • Findings • Cool, mottled upper extremity • Extremely sensitive to light touch • Claw hand • Some of the pain is mediated by Sympathetic Nerve Fibers • Results • 20 – 50 % reduction in narcotic usage
Surgical Sympathectomy • Cervical • Injury to neurovascular bundle • Trans-axillary • Poor exposure • Thoracotomy • Pain and expense • Posterior • Pain, exposure • VATS • Outpatient, low pain, good exposure

Patient Selection • Must fail conservative therapy • Topical agents • Iontophoresis • Oral medication • Botox • Must rule out secondary cause • Usually very general sweating
Patient education • Compensatory sweating • 4 to 40% • Truncal and groin • Treatment options • Sympathectomy procedure • Support group
VATS Sympathectomy technique • Supine position, sitting up, arms out • Single lumen endotracheal tube • CO2 insufflation • Two 5 mm incisions • 5 mm endoscope • Long cautery, harmonic scalpel, or clips
Surgical Technique • 5 mm Incisions posterior to Pectoralis • 5 mm port, CO2 insufflation, 15 cm H20 • 5 mm port, 5 mm Endoscope • 3 mm cautery • T2 Dan Miller, MD Emory • T3, T4 Mayfield and Houck, Reisler • Carry laterally 2 – 3 cm, Kuntz nerves. • Evacuate CO2 completely

Single Level T2 Sympathectomy • 50 patients (41 female) • T2 and accessory nerves only • Single-lumen endotracheal tube • CO2 insufflation • Single bilateral access incisions (4 mm) • 3-mm, 30-degree thoracoscope, • Electrocautery nerve division, and no chest drainage. • Median operating time was 22 minutes (14 – 35) • 100% outpatient • Pain at 3 months 1% • Outcomes • 98% no sweating (1 pt required reop for T3) • 12% compensatory sweating Miller, D et al. Ann ThoracSurg 2007;83:1850 –3
Sympathectomy Level And Compensatory Hyperhidrosis After Sympathectomy • 282 with palmarhyperhidrosis • 179 patients (64%): division at T2 level only • 103at levels T2, T3, and T4 • Operative time 19 min (14 – 30) • Hospital stay 0 – 1 days • 1% inpatient – pain • Results • 99% no sweating • 0% Horner’s Syndrome • 0% gustatory sweating • Compensatory hyperhidrosis • 23 pts in T2 group (13%) • 35 pts in T2 - T4 group (34%; P = .011) Miller, D et al.
