ABSTRACT

<p><b>OBJECTIVE</b>To illustrate the morphological characteristics of atherosclerotic lesions of the internal carotid artery.</p><p><b>METHODS</b>The morphological characteristics of cervicocerebral atherosclerotic lesions in digital subtracted angiography were retrospectively reviewed in 120 cases.</p><p><b>RESULTS</b>Totally 217 atherosclerotic lesions were detected. Of all the lesions, moderately and severely stenosed lesions accounted for 62.21% and mild stenosed lesions for 37.79%; long lesions were found in 18.89% and short ones in 81.11%; 37.33% of the lesions were ulcerated while 62.67% were non-ulcerated; 13.36% were angulated lesions and 86.64% non-angulated; 50.23% were eccentric lesions and 49.77% were concentric; lesions with adjacent artery dilation were found in 9.22%, and lesions without with adjacent artery dilation in 90.78%.</p><p><b>CONCLUSION</b>The atherosclerotic lesions are characterized by moderate to severe stenosis and non-ulcerated, non-angulated, eccentric lesions without adjacent artery dilation.</p>
