Abstract

Eighty-three patients with cerebrovascular disease were investigated by Transcranial Doppler Sonography (TCD) and Carotid Color Doppler Flow Imaging (CDFI) in order to estimate the incidence of tandem lesions in patients with extracranial carotid artery disease. According to the severity of carotid artery stenosis, the patient were classified into four groups: I- mild, II- moderate, III- severe stenosis and IV- occlusion of the carotid artery. Eight of the 22 patients in Group I (less than 50%), had very possible tandem lesions, 10 of the 28 patients from Group II (stenosis of 51-80%) possible tandem lesions, 2 of the 12 patients from Group III (stenosis of 81-99%) probable tandem lesions and 8 of the 21 patients from Group IV also probable tandem lesions. Transcranial Doppler Sonography and Color Doppler Flow Imaging are simple and noninvasive methods which give insight into intra- and extracranial hemodynamic changes which may incidate the presence of tandem lesions. The detection of tandem lesions has potential therapeutic implications.
