Abstract
Intra-Cranial Arterial Stenosis (ICAS) represents a source of risk to develop stroke. There is some genetic and ethnic determinant in having a major risk. Non invasive diagnosis rely on Trans-Cranial Doppler (TCD) and Magnetic Resonance Angiography, while Computed Tomography has the best accuracy to be compared to the more invasive Digital Subtraction Angiography. The endovascular and medical therapy options are compared, passing through WASID and SAMMPRIS trials.
