颈内动脉系统动脉粥样硬化病变的DSA形态学特征

Morphological characteristics of internal carotid artery atherosclerotic lesions in digital subtracted angiography

目的探讨颈内动脉系统动脉硬化病变的形态学特征。方法回顾分析120例动脉硬化患者颈内动脉系统动脉硬化病变,分析各病变的脑血管造影(DSA)的形态学特征。结果120例病人共217个动脉硬化病变,其中重度狭窄占62.21%,轻度狭窄占37.79%;长病变占18.89%,短病变占81.11%;溃疡病变占37.33%,非溃疡病变占62.67%;成角病变占13.36%,非成角病变占86.64%;偏心性病变占50.23%,向心性病变占49.77%;狭窄两端扩张病变占9.22%,无狭窄两端扩张病变占90.78%。结论本组颈内动脉系统脑动脉硬化病变形态学特征中,中重度狭窄、短病变、非溃疡病变、非成角病变、偏心性病变以及无狭窄两端扩张病变为其主要表现。

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% （135/217） and mild stenosed lesions for 37,79% （82/217）; long lesions were found in 18.89% （41/217） and short ones in 81.11% （176/217）; 37.33% （81/217） of the lesions were ulcerated while 62.67% （136/217） were non-ulcerated; 13.36% （29/217） were angulated lesions and 86.64% （188/217） non-angulated; 50.23% （109/217） were eccentric lesions and 49.77% （108/217） were concentric; lesions with adjacent artery dilation were found in 9,22% （20/217）, and lesions without with adjacent artery dilation in 90.78% （197/217）, Conclusion The atherosclerotic lesions are characterized by moderate to severe stenosis and non-ulcerated, non-angulated, eccentric lesions without adjacent artery dilation.
