- el flujo sanguineo de los dedos se incremento en un 700% despues de la simpatectomia
- la temperatura en los dedos aumento en 7grados despues de la simpatectomia
- muchos de los reflejos autonomicos fueron dramaticamente afectados
- la densidad de los dedos disminuyo despues de la simpatectomia. Se midio a traves de la prueba del anillo 
- los pacientes deberian de ser completamente informados antes de la simpatectomia de los efectos secundarios que acarrea

Sympathicotomy affects cutaneous blood flow, temperature, and sympathicus-mediated reflexes.Koskinen LO, Blomstedt P.

Objective - To study the sympathetically mediated effects of transthoracic endoscopic sympathicotomy (TES) in the treatment of severe primary palmar hyperhidrosis. Materials and methods - The effects of TES, on sympathetic ganglia at the thoracic level of 2-3, finger blood flow, temperature, and on heat and cold provocation were investigated. Middle cerebral artery (MCA) blood flow velocities were studied by transcranial Doppler. Results - The finger blood flow increased by about 700% after TES and finger temperature by 7.0 +/- 0.5 degrees C. Several autonomic reflexes were dramatically affected. A finger pulp-shrinking test showed a major decrease after surgery. MCA mean blood flow velocities were not affected by TES. Conclusions - Besides the high success rate of good clinical effect of TES on palmar hyperhidrosis, major effects on local blood flow and temperature are elicited by TES. Complex autonomic reflexes are also affected. The patient should be completely informed before surgery of the side effects elicited by TES.
