Extensive cerebral arteries thrombosis.

Cerebral artery thrombosis is one of the major causes of death. It is usually not clear what kind of pathologic processes participate in this pathological entity. We report a case of a 47-year old female patient with recurrent episodes of cerebral arterial thrombosis, without permanent neurological deficits and history of heavy smoking, hypertension, hypothyroidism, hypercholesterolemia, metabolic syndrome and insulin resistant postprandial hyperglycemia. Brain magnetic resonance angiography (MRA) revealed total thrombosis of the left internal carotid artery (ICA) and partial thrombosis of the right ICA. Although, the extent of the cerebral arteries thrombosis due to the coexistence of many risk factors, the clinical symptoms are mild, because of the sufficient blood supply from the vertebrobasilar system and the efficient collateral circulation.
