Allowing for the observation that only about half of patients with cervical bruits have a hemodynamically significant lesion,^3,4 the risk of relevant stroke amounts to about 0.5% per year or one quarter the risk of immediate morbidity or mortality (2%) set as a maximum by Quiñones-Baldrich and Moore.
