Preoperative carotid screening of candidates for elective cardiovascular surgery. A prospective analysis of 388 patients.

Preoperative extracranial carotid artery examination with ultrasonography in patients undergoing coronary artery bypass grafting in Japan

“…Despite some differences in the degree and prevalence of severe stenosis and the methodology, our findings generally correlate with recent reports from Europe and America. [1][2][3][4] Although there are only a few studies on extracranial carotid stenosis in Japanese patients undergoing CABG, Fukuda et al 5 reported that stenosis of greater than 80% was found in 8.1%, and Saito et al 24 reported that stenosis of greater than 75% and occlusion were observed in 11.9%. Moreover, Nagao et al 25 demonstrated that the proportion of severe atherosclerosis in the extracranial ICA examined by angiography in Japanese patients with cerebral infarction has been increasing in recent years owing to Westernization of lifestyle, which is particularly reflected in an increased incidence of diabetes in the Japanese population.…”
