DeBakey9 stated that the use of sympathetic block as a preliminary procedure to test the value of sympathectomy was not entirely dependable in degenerative arterial disease. Others3,5,7,11 also have reported that a lack of response following preoperative procaine block of the lumbar sympathetic chain did not consistently predict a lack of clinical response after sympathectomy. Early studies, for the most part, depended upon changes in the temperature of the skin after temporary inhibition or block of sympathetic activity. It was assumed that rises in temperature would be indicative of increases in the rate of blood flow in the skin and that similar improvements would
