The same year, the European Society of Cardiology stated that endarterectomy may be considered for asymptomatic patients with greater than 60% carotid stenosis if their perioperative risk of stroke or death is less than 3% and if the patients life expectancy exceeds 5 years.
In a study, the following risk factors (with odds ratios) are presented for CABG perioperative stroke; preoperative factors including carotid stenosis (%5.
They added that the USPSTF recommendation against screening the general population for carotid stenosis agrees with recommendations from the American Heart Association, American Stroke Association, American College of Cardiology, American Association of Neurological Surgeons, American College of Radiology, American Society of Neuroradiology, Society for Vascular Surgery, Society for Vascular Medicine, and the American Academy of Family Physicians.
Lai and his team conducted cognitive testing on 127 patients: 67 with ultrasound-confirmed asymptomatic carotid stenosis of 50% or more, and 60 controls.
Persons with a history of TIA or ischemic stroke within the past 2 weeks to 6 months should be considered for carotid endarterectomy or stenting for ipsilateral carotid stenosis of 50%-99%, if the peri-procedural risk of morbidity and mortality is less than 6%.
To date, the only approved nonmedical treatment method of carotid stenosis is carotid endarteractomy (CEA); stenting is currently reserved only for those patients who fall into the high-risk category (Centers for Medicare and Medicaid Services, 2008).

Researchers from both medical and technical fields report on such aspects as deformable registration using spring mass system with cross-section correction, evaluating the computer-assisted quantification of carotid stenosis, visualizing a skeletal dysplasia knowledge base, and a novel medical image segmentation method using dynamic programming.
These guidelines will help reduce the death and disability rates associated with stroke by identifying carotid stenosis in a timely manner, allowing treatment before a stroke occurs.
Per definition, none of the 433 controls had coronary artery disease, cerebrovascular disease, or internal carotid stenosis [greater than or equal to]50%, but many (n = 365) had carotid plaques, indicating mild but not clinically relevant atherosclerosis.
