Recurrent hyperhidrosis is another potential side effect from hyperhidrosis surgery

The Society of Thoracic Surgeons Expert Consensus for the Surgical Treatment of Hyperhidrosis -- Cerfolio et al. 91 (5): 1642 -- The Annals of Thoracic Surgery: "Recurrent hyperhidrosis is another potential side effect from hyperhidrosis surgery. Incidence rates vary considerably and have been described as 0% to 65%"

The Society of Thoracic Surgeons Expert Consensus for the Surgical Treatment of Hyperhidrosis -- Cerfolio et al. 91 (5): 1642 -- The Annals of Thoracic Surgery: "Because the goal of this procedure is to improve quality of life, complications should be minimal and essentially eliminated. The primary side effects of hyperhidrosis surgery include CH, bradycardia, and Horner's syndrome. It is important for patients to be aware, however, of all of the possible complications that can occur. In general, "the higher the level of blockade on the chain, the higher is the expected regret rate" [26]."

The vasodilating effect of spinal dorsal column stimulation is mediated by sympathetic nerves - Springer

The vasodilating effect of spinal dorsal column stimulation is mediated by sympathetic nerves - Springer: "Immediately after sympathectomy, the contralateral right arm became increasingly cold and cyanotic and the patient complained of chronic painful coldness and severe cold-intolerance in the right arm. Attempts to pharmacologically vasodilate the arm with felodipine did not affect the local vasoconstriction and pain. Dorsal column stimulation (associated with symmetrical paraesthesia in both arms) induced an immediate and marked (ten-fold) increase in skin blood flow in the right arm (and in the leg), whereas skin blood flow in the left arm remained unaffected. The lack of vasomotor response in the left arm was not due to maximal vasodilatation at rest, since skin blood flow in the left arm showed a normal capacity for axon reflex vasodilatation following antidromic activation of sensory afferents. The results suggest that the marked vasodilatation induced by dorsal column stimulation is mediated by sympathetic vasomotor fibres, via modulation of central neuronal circuits involved in the regulation of skin sympathetic discharge."

Transection below T8-T10 is not accompanied by reflex sweating

Reflex sweating in patients with spina... [Arch Phys Med Rehabil. 1977] - PubMed - NCBI: "Sweat glands derive their innervation from the sympathetic nervous system. The spinal sympathetic structures that are located in the intermediolateral areas extend from T1-L2 segments and are under the control of hypothalamic centers. Cord transection abolishes the supraspinal control of sudorimotor function. Since sympathetic innervation does not follow a clear segmental distribution, normal sweating may be preserved at a higher or lower level than skin sensation. Nonthermoregulatory reflex sweating is an indication of unchecked spinal cord facilitation and is precipitated by afferent stimuli from bladder, rectum, and various other sources. It is usually a manifestation of mass reflex or autonomic crisis and occurs particularly in cervical or high thoracic lesions. Transection below T8-T10 is not accompanied by reflex sweating. The phenomenon of thermal relfex sweating is controversial. Although some aspects of nonthermoregulatory reflex sweating are still unclear, proper immediate and continuing preventive management will reduce the incidence of this and other autonomic manifestations.
