We studied 4 patients with bilateral carotid artery occlusion who suffered
delayed TIAs in one of the occluded internal carotid or common carotid
areas. Hemodynamic mechanisms were prominent in two patients, in head
turning and orthostatic hypotension. In the other two cases, embolic
phenomena through the homolateral external carotid collateral pathways were
probable, because this artery (or the common carotid artery) showed
atheromatous stenosis and major collateral supply to the brain and retina.
Different mechanisms may be responsible for further ischemia after
bilateral occlusion of carotid arteries.
