What is the role of preoperative carotid artery noninvasive screening in CABG patients?
The role of preoperative carotid artery noninvasive screening in CABG patients is to reduce stroke rates. Noninvasive screening using ultrasound imaging is recommended to identify carotid artery stenosis ≥50% that may require revascularization or medical management prior to CABG. Such screening can help to reduce the risk of stroke after CABG. Additionally, carotid artery stenting prior to CABG may also reduce the risk of stroke. However, carotid artery stenting is not recommended in asymptomatic patients with carotid artery stenosis <70%.
