[Morphological characteristics of internal carotid artery atherosclerotic lesions in digital subtracted angiography].
OBJECTIVE
To illustrate the morphological characteristics of atherosclerotic lesions of the internal carotid artery.


METHODS
The morphological characteristics of cervicocerebral atherosclerotic lesions in digital subtracted angiography were retrospectively reviewed in 120 cases.


RESULTS
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%.


CONCLUSIONS
The atherosclerotic lesions are characterized by moderate to severe stenosis and non-ulcerated, non-angulated, eccentric lesions without adjacent artery dilation.
