OBJECTIVE: To determine frequency of carotid artery disease in patients undergoing elective coronary artery bypass grafting (CABG) using Doppler sonography. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Radiology Department, The Aga Khan University Hospital, Karachi, from January 2005 to September 2008. METHODOLOGY: Patients with known cardiovascular disease waiting for CABG surgery were enrolled for carotid artery Doppler sonography. A predefined data entry form was used for data collection. Coronary angiography findings, carotid artery findings and other associated factors were noted from medical and radiological records. Frequency and pattern of carotid artery disease along with associated risk factors were evaluated. Data was entered and analyzed in SPSS version 15. Pearson chi-square for categorical and independent "t" test was applied for continuous variables at 95% confidence level. P-value of less than 0.05 were considered significant. RESULTS: A total of 176 patients (85% male, mean age=65 years) undergoing elective coronary artery bypass grafting were evaluated preoperatively for carotid artery disease by neck color Doppler sonography. Twenty percent of patients were found to have advanced carotid artery disease (> 50% stenosis), 6% had critical stenosis (> 75% stenosis) and 3% had complete stenosis. Frequency of atherosclerotic plaques was 50%, more common on right side and more prevalent in common carotid artery. Family background of carotid or coronary artery disease and history of smoking were significantly associated with presence of carotid artery disease (p < 0.05). CONCLUSION: A sizeable proportion of patients undergoing elective coronary artery bypass grafting surgery for coronary artery disease were found to have coexistant carotid artery disease.
