Mandatory versus selective preoperative carotid screening: a retrospective analysis

2011 ACCF/AHA Guideline for Coronary Artery Bypass Graft Surgery

“…A retrospective analysis of 1421 consecutive CABG patients identified the following as risk factors for significant carotid artery disease: age Ͼ65 years, presence of a carotid bruit, and a history of cerebrovascular disease. 858 In so doing, they reduced preoperative testing by 40%, with only a "negligible" impact on surgical management or neurological outcomes. Similarly, the following risk factors have been identified as predicting the presence of Ͼ50% reduction in internal diameter of the internal carotid artery: smoking, diabetes mellitus, hypertension, a previous cerebrovascular event, PAD, left main CAD, and a history of cervical carotid disease.…”

Imaging of the carotid arteries: the role of duplex ultrasonography, magnetic resonance arteriography, and computerized tomographic arteriography

“…Although carotid artery imaging prior to coronary artery bypass graft surgery is controversial and beyond the scope of this manuscript, it remains an important area of debate among clinicians. 7 A recent review of the literature suggests that a carefully planned approach using non-invasive imaging can replace invasive angiography for carotid artery assessment in a cost-effective and safe manner. 8 Currently, indications for carotid duplex ultrasonography (DUS) which are acceptable for reimbursement include: cervical bruit; amaurosis fugax; focal or cerebral transient ischemic attacks; drop attacks or syncope; episodic dizziness with symptoms characteristics of transient ischemic attacks; evaluation and follow-up of cervical bruits (http://www.empiremedicare.com/newypolicy/policy/ l3743_final.htm).…”

Prevalência de estenose carotídea em pacientes com indicação de cirurgia de revascularização miocárdica

“…Others, only in cases presenting high risk: age older than 65 years 36 , cervical bruit at physical examination, previous CVA or transient ischemic attack, peripheral obstructive arterial disease, systemic arterial hypertension, left coronary artery trunk stenosis, history of smoking, diabetes mellitus and aortic arch atherosclerosis 37 .…”
