Phenol sympathetic block is valuable for the treatment of ischemic pain, gangrene, intermittent claudication, Pager's disease of the bone and pain associated with pancreatitis, pancreatic cacinoma, etc. The author has experienced a case of successful lumber sympathetic block using 7% phenol under fluroscopy and given to a patient with Buerger's disease who had severe pain and ulceration of the right great toe for several years. After the sympathetic block, 2 epidural blocks with 2.5% bupivacaine were done in order to augment the effects of this sympathetic block. Subsidence of rest pain, increase in walking distance from under 100M to over 500M and circulatory improvement of the affected limb were observed. Imporvement of circulation was confirmed by strain gauge plethysomgraphy.
