AbstractOf 2,667 patients with herpes zoster who visited our hospital between January 1972 and March 1989, 136 patients whose treatments were started after more than 6 months following the onset were subjects of the present study. Thus we performed a retrospective study of the therapeutic effects of sympathetic ganglion block (using alcohol) on postherpetic neuralgia left untreated for more than 6 months after the onset. After more than 1 year following the onset, the disease was nearly or completely cured in 9 of 37 patients (24%) treated with sympathetic ganglion block with alcohol and in 6 of 34 (17.6%) without the treatment. Thus the patients who underwent sympathetic ganglion block with alcohol tended to show better results. The above findings suggest that, in patients with postherpetic neuralgia in whom the initiation of treatment was delayed, treatment mainly consisting of thoracic or lumbar sympathetic ganglion block using alcohol in combination with antidepressants and antianxiety drugs can greatly improve patients' activities of daily life and that, at present, this method is most effective in relieving postherpetic neuralgia.
