The recent advent of more energetic medical regimens for the treatment of essential hypertension has led to the need for reevaluating the patients who were treated surgically for this disease by means of thoracolumbar sympathectomy. The pertinent questions to be answered by such an evaluation are the extent of long-term symptomatic improvement, the degree and duration of blood pressure depression, and, finally, the predictability as to which patient will benefit from such an operative procedure.
By means of recent correspondence or personal examination, patients who underwent surgery at least eight years prior to this study were evaluated. Ninety patients from the private surgical services of the Strong Memorial Hospital were studied. The distribution according to sex was four males to five females. The average age of the females and males was essentially identical at 42.5 years. The oldest patient in this group was 57 and the youngest 20.
