Bilateral internal carotid artery occlusion with compensatory perfusion in a HIV-infected patient
HIV infection occlusive arteriopathies may result in neurological symptoms. We report a case of bilateral complete occlusion of the extracranial portions of the internal carotid arteries in a HIV+ve patient who presented with a syncopal episode due to intraventricular haemorrhage. Compensatory blood flow from the posterior cerebral circulation via the circle of Willis resulted in small telangiectatic vessels arising from the posterior cerebral circulation which probably accounted for this rare haemorrhagic complication of an occlusive arteriopathy.
