Prediction of Hyperperfusion After Carotid Stenting by Multi-parameter Characteristics Based on Cerebral Autoregulation

The procedures will be performed for patients with general or local anesthesia. Implantation of stents at the site of carotid artery stenosis for the treatment of carotid severe stenosis. A suitable balloon will be selected based on the internal carotid arterial（ICA）diameter, as shown on the digital subtraction angiography（DSA）image. The use of a balloon for predilatation or postdilatation depends on the degree of stenosis. The type of stent will be selected according to several factors, such as the length and configuration of the lesion, vascular morphology, vessel diameter, plaque characteristics, stent characteristics, and surgeon experience.
