16. Recommendations for Carotid Artery Evaluation and Revascularization Before Cardiac Surgery Class IIa Carotid duplex ultrasound screening is reasonable before elective coronary artery bypass graft (CABG) surgery in patients older than 65 years of age and in those with left main coronary stenosis, PAD, a history of cigarette smoking, a history of stroke or TIA, or carotid bruit. (Level of Evidence: C) Carotid revascularization by CEA or CAS with embolic protection before or concurrent with myocardial revascularization surgery is reasonable in patients with greater than 80% carotid stenosis who have experienced ipsilateral retinal or hemispheric cerebral ischemic symptoms within 6 months. (Level of Evidence: C) Class IIb In patients with asymptomatic carotid stenosis, even if severe, the safety and efficacy of carotid revascularization before or concurrent with myocardial revascularization are not well established. (Level of Evidence: C) 2011 ASA/ACCF/AHA/AANN/AANS/ACR/ASNR/CNS/SAIP/SCAI/SIR/SNIS/SVM/SVS Guideline on the Management of Patients With Extracranial Carotid and Vertebral Artery Disease: Executive Summary

Carotid stenosis revascularization and preoperative risk of stroke – what everybody seems to agree on Asymptomatic unilateral – no benefit Asymptomatic bilateral – debatable Symptomatic – should be revascularized Most strokes in patients without carotid stenosis ( most often in posterior brain circulation) Naylor AR J Cardiovasc Surg 2009 Mahmoudi Stroke 2011

What is asymptomatic severe stenosis? Silent embolic infarcts on computed tomography brain scans and risk of ipsilateral hemispheric events in patients with asymptomatic internal carotid artery stenosis. * 2 fold increase of stroke on FU CONCLUSION: The presence of silent embolic infarcts can identify a high-risk group for ipsilateral hemispheric neurologic events and stroke and may prove useful in the management of patients with moderate asymptomatic carotid stenosis. - CT of our patient revealed silent ischemic cortical lesions on the right hemisphere *Kakkos SK, et al. Asymptomatic Carotid Stenosis and Risk of Stroke (ACSRS) Study Group J Vasc Surg. 2009

Early CAS experience ? No report on operator experience No strokes reported while waiting for CABG – mean 32 days !! CAS and wait before CABG – high rate of AE

Same day CAS on RICA and CABG+AVR on heparin and aspirin(SHARP protocol)

Peculiarities of same day CAS+CABG Use your usual technique No clopodogrel Preload Aspirin + statin Heparin ACT >200 until transferred to OR Replace the long sheet with short one and suture to the skin at the end of procedure

Take home message Carotid Revascularization should be part of heart team decision CAS or CEA based on results of local operators Simultaneous or staged procedure – urgency of coronary revascularization is decisive but excess of coronary event is observed in a waiting period

Thank u for your attention!
