Psychoneurological applications of endoscopic sympathetic blocks (ESB).

In addition to more widely and longer known indications of ETS, various neurological disorders and psychologically stressful situations in their worst expressions might be alleviated by the reversible ESB procedure. The patients with social phobia, especially those who have also blushing and/or stage fright type of heart racing, benefit from the ESB. The disturbances of the sympathetic nervous system, e. g. in Parkinson's disease and multiple system atrophy might be alleviated with sympathetic block, especially the extrapyramidal symptoms in these diseases. In migraine, sympathetic surgery has been noted to give some help. The unilateral left-sided block has been effective in long QT-syndrome type arrhythmias. In schizophrenia, the phobic, paranoic or confusional reactions have been tentatively treated by the sympathetic block.
