Choosing Wisely: A good start to explaining vascular best practices
Avoid use of ultrasound for routine surveillance of carotid arteries in the asymptomatic healthy population at any time.
The presence of a bruit alone does not warrant serial duplex ultrasounds in low-risk, asymptomatic patients, unless significant stenosis is found on the initial duplex ultrasound. The presence of asymptomatic severe carotid artery disease in the general population yields a risk of neurologic events which is <2%. Even in patients who have a bruit, if no other risk factors exist, the incidence is only 2%. Age (over 65), coronary artery disease, need for coronary bypass, symptomatic lower extremity arterial occlusive disease, history of tobacco use and high cholesterol would be appropriate risk factors to prompt ultrasound in patients with a bruit. Otherwise, these ultrasounds may prompt unnecessary and more expensive and invasive tests, or even unnecessary surgery. In general population-based studies, the prevalence of severe carotid stenosis is not high enough to make bruit alone an indication for carotid screening. With these facts in mind, screening should be pursued only if a bruit is associated with other risk factors for stenosis and stroke, or if the primary care physician determines you are at increased risk for carotid artery occlusive disease.

How This List Was Created
The Society for Vascular Surgery (SVS) formed a task force to gather initial recommendations for a list of procedures that should not be performed, performed rarely or performed only under certain circumstances.
These draft recommendations were then sent to the Public and Professional Outreach Committee, which refined them before presenting them to its reporting council, the Clinical Practice Council. The Council reviewed the citations and ensured all recommendations aligned with SVS Clinical Practice Guidelines before submitting them to the Executive Committee of the SVS Board of Directors for approval.
You can review the society’s conflict of interest and disclosure policy at www.vsweb.org/COIpolicy.
About SVS
The Society for Vascular Surgery advances the care and knowledge about vascular disease, which affects the veins and arteries of the body, to improve lives everywhere. It counts more than 5,000 medical professionals worldwide as members, including surgeons, physicians, and nurses.
