Having confirmed the development of cephalea in a large number of patients undergoing saphenectomy under subarachnoidal anasthetic, the authors wanted to research its probable causes. With this in mind, they observed a group of patients who had varices of the lower limbs which they had operated. They present their study methodology, and then examine and discuss the results. The conclude that many factors are responsible for the aetiology of the symptoms of cephalea. The sex, age, and conditions of venous hypertension in the posterior tibial vein are particularly determining factors.
