Kharche Dr. Pankaj Banode Dr. September 2017 6 9 01 02 ABSTRACT

 Intracranial atherosclerotic stroke (ICAS) is responsible for ischemic stroke in 10~33%. ICAS occurs in association with various stroke mechanisms, such as in situ thrombotic occlusion, artery–to–artery embolism, hemodynamic insufficiency, and branch occlusion. (1)

 

Thus, for patients with Carotid artery stenosis of 60% to 70% its identification is important with regards to management, allowing appropriate referral for carotid endarterectomy. Risk factors for disease at the carotid bifurcation include atherosclerosis, hypertension, diabetes mellitus, hyperlipidaemia, hypercholesterolemia, obesity, and smoking. Risk factor modulation is the key to the management of atherosclerosis, but in the treatment of carotid disease, imaging has utmost role to play.
