The surgical significance of the anatomy of the parasellar venous structures and their relationship to the carotid artery are discussed. Two points emphasized are that it is possible to operate within the cavernous sinus and still be outside both the venous and arterial components of the fistula, and that, by one means or another, the carotid should be preserved.
