THE USE of cervical carotid artery-internal jugular vein anastomosis as a means of revascularizing the brain has been championed by Beck, McKhann, and Belnap.1 Experimental work in the rhesus monkey2 revealed that such an anastomosis does not result in increase in the oxygen content of the superiorsagittal sinus blood; in many of the experiments the oxygen content of the superior sagittal sinus blood is actually lower after the shunt. Angiographic studies in the rhesus monkey after a shunt reveal that blood usually courses up one jugular vein to the lateral sinus and across to the opposite lateral sinus and down the contralateral jugular vein or it courses through the tributaries in the neck to the opposite jugular vein. Tarlov and others3 found that in carotid artery-internal jugular vein shunts in human beings the postoperative angiographic pattern is essentially the same as the results of the above-described work
