An Unusual TIA


This case demonstrates that the diagnosis of carotid occlusion is important to make as it confers a high future risk of stroke. Advanced neuroimaging that consists of SPECT, transcranial Doppler ultrasound or CT or MR perfusion studies may be able to demonstrate reduction, or inducible reduction, in cerebral blood flow in the appropriate carotid vascular territory. Medical therapy consists of management of vascular risk factors including hypertension and hypercholesterolaemia and the initiation of antiplatelets. This may be supplemented with revascularization of a contralateral carotid stenosis or extracranial-intracranial bypass surgery to alleviate symptoms. However, this technique is not proven to reduce the incidence of ispilateral stroke and is associated with considerable periprocedural mortality.
