Treatment of Carotid Artery-Cavernous Sinus Fistula

In 1933 Hamby and Gardner¹reported their observations following several surgical procedures which they employed in an attempt to bring about cure in two cases of fistula between the carotid artery and the cavernous sinus. In their case of significance in the present discussion (case 2) the patient had, in the order given, ipsilateral ligation of the extracranial portion of the internal carotid artery and the common carotid artery, ligation of the intracranial portion of the internal carotid artery distal to the lesion and finally ligation of the extracranial portion of the internal carotid artery and the common artery contralateral to the fistula. Two years later Dandy²reported the results following ligation (clipping) of the intracranial portion of the internal carotid artery in two patients who had a traumatic fistula between the cavernous sinus and the internal carotid artery. In each of these two instances there had
