摘要
目的 探讨颈部血管病变与脑梗死的相关性。方法 自颈总动脉近心端开始,分别取其短轴和长轴切面,由近而远逐渐向远心端扫查,观察颈总动脉及其分又处、颈内动脉和椎动脉内-中膜厚度和形态、斑块及血流情况。结果 129例脑梗死患者中有110例共329支颈部动脉患有不同程度的硬化,100例共178支动脉有硬化斑块。13例14支动脉为中度至严重狭窄;3例3支颈内动脉为完全闭塞,不能引出血流频谱和血流色彩。结论 颈动脉粥样硬化所形成的颈动脉狭窄和斑块是缺血性脑病的病理基础,颈动脉粥样硬化附壁血栓脱落、斑块的破裂出血可以成为大片脑梗死或腔隙性脑梗死的主要原因。
Objeetive To investigate the relations between cervical vascular lesion and cerebral infarction. Methods The thickness, shape, spot, and blood flow were observed from the proximid end to distad end. Results Among the 129 cases, 339 carotid artery in 110 cases were sclerosis in difference. 178 carotid artery in 100 cases had sclerotic spots. 14 artery in 13 cases Were stenosis rnoderatly and seriously. 3 internal carotid artery in 3 cases were obliteration entirely. Conclusions Duing to the form of carotid artery atheromatous sclerosis, stensis and spots were the main causes for exfoliated thrombus and spots repture so as to leading cerebral infarction or lacunar cerebral infarction.
