“…We detected AC in nearly half of our patients, which was an independent predictor for embolic complications after CAS. In good agreement with previous studies, this atherosclerotic risk factor was associated with advanced age [24], a high incidence of coronary artery disease [22,24] as well as with diabetes mellitus [25]. During the past years, an increasing number of clinical and anatomical risk factors for CAS have been identified, including advanced age [4,21,26,27], the symptom status of the stenosis [19,21], the presence of severely ulcerated or long stenosis [12,23,27,28] or cardiovascular risk factors such as diabetes mellitus [28].…”
