Aim. In this study, it has been questioned whether carotid Doppler USG should be considered as a routine investigation who will undergo CABG and frequency of carotid artery disease concomitantly with coronary artery disease in the cases that will undergo elective coronary artery bypass surgery.
Methods. The study included 250 patients that have been operated CABG consecutively. Bilateral carotid arteries of all the patients with or without any neurological symptom (recent TIA or stroke) were evaluated by B-mode Color Doppler USG.
Results. Total occlusion, severe carotid artery stenosis (≥70%) and narrowness (50%≤ and ≤70%) were detected in 2, 20 and 13 patients, respectively. The 20 patients were performed concomitant CABG and carotid endarterectomy (CEA). The sensitivity 0.40 and specificity 0.74 were calculated for carotid Doppler USG.
Conclusion. Consequently, carotid Doppler is an easy-applicable and low-cost method for both physician and the patient. In our study group, severe stenosis was detected in a 4.8% population whereas no symptom or finding was determined. We consider this rate to be significant when the frequency of peroperative neurological complication was taken notice. Therefore, we conclude that performing Preoperative Carotid Doppler Investigation as a routine examination would be helpful.
