![]() However, there are known harms associated with the confirmatory testing and interventions (e.g., computed tomography, magnetic resonance imaging, and invasive angiography). There is inadequate direct evidence that screening for asymptomatic carotid artery stenosis can cause harm. Additionally, there is evidence that treating asymptomatic patients with surgical or catheter-based procedures provides no to small benefit in reducing adverse health outcomes as compared to current medical therapy. ![]() There is inadequate direct evidence that screening for asymptomatic carotid artery stenosis reduces adverse health outcomes (e.g., stroke, mortality). However, it may yield false-positive results when used for general population screening.Īuscultation of the neck for carotid bruits has poor accuracy for detecting clinically relevant carotid artery stenosis.
