Abstract

Carotid stenosis is an important cause of transient ischemic attacks and stroke. The cause of carotid stenosis is most often atherosclerosis, which account for up to 10% to 20% of brain infarction causes. The annual stroke risk for patients with asymptomatic stenosis of the carotid artery is around 1% increase of < 70% stenosis and 2-5% in patients with > 70% stenosis. The risk of recurrent ischemic events for patients with symptomatic stenosis is much higher, around 15% during the first year. Carotid stenosis can be diagnosed by duplex ultrasound, magnetic resonance angiography, and carotid angiography. Each has different diagnostic accuracy. CAS is undergoing rapid evolution. The technique of carotid artery stenting include the use of stiff guide wire to access the lesion it’s important not to cross the lesion with the guide wire to prevent embolization, then sizing of the carotid vessels to use the correct diameters of balloons stents and cerebral protection devices, then balloon dilatation and stenting is done. Cerebral protection during CAS is very important to reduce embolic complications. Cerebral protection can either be done by balloon occlusion technique or the use of cerebral protection devices or reversal of internal carotid artery flow. Conclusion: CAS is a nearly equivalent alternative to carotid end arterectomy with certain indications and contraindications however it is less cost effective.
