Surgical treatment of our patients suffering from cavernous sinus fistula, certain types of aneurysms of the internal carotid artery and internal carotid artery stenosis involved either temporary or permanent occlusion of the affected internal carotid artery. Before interrupting the blood flow through the affected internal carotid artery, it is important to find out whether the collateral cerebral circulation can tolerate this inherent reduction of blood flow. We attempted to find a solution to this problem by studying the effects of carotid compression of the affected carotid artery on the EEG. Carotid compression tests (CCT) under different arterial oxygen pressures (aPO2) should clarify the question whether a positive clinical or EEG effect is an ischemic hypoxic reaction.
