Abstract

Carotid artery disease is thought to be a risk factor for neurological complications after cardiac surgery. Routine ultrasonographic screening is still not performed in every patient scheduled for coronary artery bypass grafting (CABG). To assess factors which may facilitate the selection for elective carotid artery ultrasound examination in patients undergoing CABG. 682 patients (mean age 63.2 +/- 8.7, range: 37-85 years) scheduled for CABG underwent preoperative duplex ultrasound examination of the carotid arteries. The following factors were collected and analysed: age, sex, LVEF, history of cerebrovascular accidents (stroke and/or TIA), myocardial infarction, and presence of hypertension, diabetes, unstable angina, chronic obstructive pulmonary disease, chronic kidney disease, left main stenosis > or = 50%, lower-extremity peripheral arterial disease, and obesity (BMI > 30 kg/m(2)). Logistic regression analysis was used to determine the risk factors for carotid artery stenosis. Internal or common carotid artery stenosis > or = 50% was detected in 123 (18%) patients. Bilateral stenosis occurred in 35 (5.1%) patients, of whom 29 (4.5%) presented at least a monolateral vessel diameter reduction of > or= 70%. History of cerebro...Continue Reading
