Alteration in cardiovascular function and body surface temperature during percutaneous stereotactic upper thoracic ganglionectomy and sympathectomy in palmar hyperhidrotic patients.
We assessed changes in cardiovascular function, specifically arterial blood pressure and heart rate in 6 palmar hyperhidrotic patients before, during, and after T2 and T3 ganglionectomy and sympathectomy. We also assessed changes in skin temperature, specifically at the forehead, axilla, thumb, loin, and sole of the foot (all bilaterally) in 10 palmar hyperhidrotic patients before, during, and after T2 ganglionectomy and sympathectomy. In both methods, ganglionectomy and sympathectomy were done by percutaneous stereotactic thermocoagulation, under local anesthesia, at room temperature 21.4 +/- 0.6 degrees C. During the procedure we found a significant acute decrease in systolic and pulse pressures, from 153 +/- 10 to 127 +/- 9 and from 80 +/- 7 to 56 +/- 4mmHg respectively, and a lesser decrease in diastolic pressure; heart rate showed no statistically significant changes. We also noted a marked increase in thumb temperature, from 21.2 +/- 0.6 to 36.0 +/- 0.1 degrees C, with a mean increase of 14.8 degrees C, at a room temperature 21.4 +/- 0.6 degrees C, after complete bilateral T2 ganglionectomy and sympathectomy. Skin temperature at the forehead, axilla, loin, and sole of the foot, all measured bilaterally, showed no significant increase, although there was a decrease in sweating in both forehead and axillary regions. The decrease in systolic and pulse pressures observed during the thermocoagulation procedure were temporary effects. The increase in thumb temperature, however, appears to be a permanent effect for palmar hyperhidrotic patients. Finally, the data indicate that the sympathetic innervation of the blood vessel in the periphery presents a segmental organization.
