Abstract］ objective to identify the relationship between serum homocysteine and carotid artery atherosclerosis in patients with cerebral infarction and effects of foliate,methylcobalamin.methods the concentrations of hcy were determined by means of fluorescence polarization immunoassay and carotid arteries was examined with color doppler ultrasound in 165 patients with cerebral infarction.the subjects were divided into 4 groups according to the severity of lesion of carotid artery.the concentrations of hcy were compared in different groups.the patients with hyperhomocysteinemia received foliate and methylcobalamin.results when lesion of carotid artery became severer,serum hcy was higher.the intima medial thicknesses of carotid artery were significantly decreased in patients with hyperhomocysteinemia who received foliate and methylcobalamin for two years.conclusion hyperhomocysteinemia may play an important role in development of carotid artery atherosclerosis.the intervention of foliate and methylcobalamin may reduce carotid artery atherosclerosis.

摘要］ 目的探讨脑梗死患者颈动脉病变与血清同型半胱氨酸水平的关系及叶酸、甲钴胺长期干预对其影响。方法对165例急性脑梗死患者进行血清hcy的测定及颈动脉超声检查，并按动脉硬化的程度分组，比较不同程度颈动脉粥样硬化患者hcy水平，部分高hcy血症患者给予叶酸、甲钴胺干预，随访2年。结果随着颈动脉病变程度的加重，血清hcy浓度呈上升趋势，高hcy血症干预者动脉内中膜厚度明显减小。结论高hcy血症对颈动脉粥样硬化的形成起重要作用，长期给予叶酸、甲钴胺干预可能减轻颈动脉粥样硬化。

RESULTS: The imaging features of CBT were masses located at the bifurcation of the carotid artery, with abundant blood supply in the tumor, the internal and external carotid arteries shifted, the bifurcation of the carotid artery increased like goldcup in DSA. The imaging features of the neurilemmoma were masses located behind the bifurcation of the carotid artery, and the carotid bifurcation was normal, no blood supply in the tumor, but carotid arteries shifted.

结果：颈动脉体瘤的CDFI和DSA特征为：颈总动脉分权处单发性肿块，并与其紧密相连，瘤体内血流极为丰富，瘤体使颈外动脉向前内移位、颈内动脉向后外移位，颈内、外动脉分权角度增大明显，DSA呈高脚杯状改变；神经鞘瘤紧邻颈动脉，颈总动脉分权处角度无改变，瘤体内血流信号不丰富，瘤体使颈动脉向前、外移位。

1.Preliminary studys on the carotid artery parameters Detected by Intracavitary Convex Array ProbePurpose and SignificanceFinal results of The North American Symptomatic Carotid Endarterectomy Trial and the MRC European Carotid Surgery Trial displayed that carotid artery must be observed intimately when stegnosis degree is higher than 50%and it must have an operation or interventional therapy in time when stegnosis degree is higher than 70%.

1、腔内凸阵超声探头检测颈动脉参数的初步研究目的和意义北美有症状颈动脉内膜剥脱试验(The North American Symptomatic CarotidEndarterectomy Trial NASCET)和欧洲颈动脉手术试验(European Carotid SurgeryTrial，ECST)研究结果显示，当颈动脉狭窄程度超过50%时要密切观察病情变化，当狭窄程度超过70%时要及时手术或介入治疗，治疗后可大幅降低脑梗死的发生率。
