Abstract
Stellate ganglion block (SGB) was effective in reinitiating menstrual cycle regularity in patients with amenorrhea of hypothalamic origin. Four patients whose initial complaints had been headache or other non-gynecological problems underwent stellate ganglion block as a primary therapeutic regimen. The effect, we suspect, was due to SGB-induced alteration of blood flow to and thus temperature of the hypothalamus. This in turn corrected a more general endocrinological disturbance. Other possible causes may include amelioration of headache or related other problems with resultant improvememt in overall condition or other nonspecific effects.
