Video-assisted and thermometrically controlled thoracoscopic sympathectomy demonstrates new ways in the treatment of upper-limb hyperhidrosis. An anatomical portrayal of the sympathetic chain is possible as a result of the improved visualization and magnification of the operative area provided by the video-optic technique. The difference in temperature, registered by means of a thermometric sensor in the palm of the hand, indicates that the sympathetic nerves responsible for the hyperhidrotic segments have been severed. The number of postoperative Horner's syndromes will be reduced significantly with this method. Until now, we have successfully treated six thermometrically controlled patients. No recurrences have arisen during an 18 months observation period. Neither intraoperative nor postoperative complications were recorded. One patient complained of increased compensatory sweating of the trunk. Thermometrically controlled thoracoscopic sympathectomy is expected to improve the various forms of treatment available for sympathetic reflex dystrophies in the future.

“…Most of the methods use the increase in tissue blood flow, such as skin thermometry (LINDER et al, 1993;REX et al, 1998;WILKINSON, 1996), laser Doppler flowmetry (REx et al, 1998) and venous occlusion plethysmography (KARDOS et al, 2000). it should be noted that a significant discrepancy was found between thermometry and laser Doppler flowmetry data.…”

The photoplethysmographic (PPG) signal, which measures cardiac-induced changes in tissue blood volume by light transmission measurements, shows spontaneous fluctuations. In this study, PPG was simultaneously measured in the right and left index fingers of 16 patients undergoing thoracic sympathectomy, and, from each PPG pulse, the amplitude of the pulse (AM) and its maximum (BL) were determined. The parameter AM/BL is proportional to the cardiac-induced blood volume increase, which depends on the arterial wall compliance. AM/BL increased after the thoracic sympathectomy treatment (for male patients, from 2.60+/-1.49% to 4.81+/-1.21%), as sympathetic denervation decreases arterial tonus in skin. The very low-frequency (VLF) fluctuations of BL or AM showed high correlation (0.90+/-0.11 and 0.92+/-0.07, respectively) between the right and left hands before the thoracic sympathectomy, and a significant decrease in the right-left correlation coefficient (to 0.54+/-0.22 and 0.76+/-0.20, respectively) after the operation. The standard deviation of the BL or AM VLF fluctuations also reduced after the treatment, indicating sympathetic mediation of the VLF PPG fluctuations. The study also shows that the analysis of the PPG signal and the VLF fluctuations of the PPG parameters enable the assessment of the change in sympathetic nervous system activity after thoracic sympathectomy.
