Assessment of Carotid Artery Stenosis and Lower Limb Peripheral Ischemia Prior to CABG

From our experience among Egyptian population in our institution, there is an increased prevalence of hidden subclinical peripheral artery disease along with carotid artery affection. Thus, increasing the risk of post-operative morbid complications.We aim to evaluate routine/ non-selective carotid and peripheral arterial screening in asymptomatic patients undergoing coronary artery bypass grafting in the Egyptian populationIt is a prospective, non-randomized, comparative study including two groups of patients. The study will start from the day of approval of the ethical committee. It will include 260 patients, on basis of "all new comers". Patients will be examined and classified as "high-risk" group (ɳ = 130) or "low-risk" group (ɳ=130). All patients will have the "routine" preoperative investigations along with evaluation of extracranial carotid system by non-invasive carotid duplex and lower limb arterial system by non-invasive bilateral lower limb arterial duplex.
