Bilateral complete carotid and basilar artery occlusion in a patient with minimal deficit

Clinico-radiological study of collateral circulation after internal carotid and middle cerebral occlusion

“…Fields, Edwards, and Crawford (1961) described 16 cases of bilateral internal carotid occlusion, only 10 of whom presented with a stroke, the remaining six showing only minimal deficit. Doniger (1963) described a patient with bilateral carotid and basilar artery occlusions who had only minor impairment. Angiography in this patient showed filling of the anterior and middle cerebral arteries on both sides via the ophthalmic arteries which were hypertrophied.…”

Bilateral internal carotid artery occlusion secondary to closed head injuries

“…The potential efficacy of anastomosis to the central nervous system can be judged from Doniger's (1963) report in which complete bilateral occlusion of the internal carotid arteries and complete occlusion of the basilar artery was verified angiographically in a 48year-old woman. Neurological deficit was minimal.…”

Delayed TIAs distal to bilateral occlusion of carotid arteries -- evidence for embolic and hemodynamic mechanisms.

“…For a long time it was thought to be incompatible with life, but a few studies showed that patients may survive this condition, sometimes with a fairly benign outcome. [1][2][3] A few studies dealt with the prognosis of BCO, 4-6 but little attention has been paid to the occurrence of further ischemic events in the areas supplied by the occluded carotid arteries. We now report 4 patients with BCO, demonstrated on angiography who later suffered delayed TIAs in one of the occluded artery areas.…”
