【摘要】：目的探讨颈总动脉血流动力学参数判断颈内动脉狭窄程度的价值。方法选择单侧颈内动脉中度及以上狭窄或闭塞、对侧同名动脉无狭窄或轻度狭窄者255例,根据颈内动脉狭窄程度分为颈内动脉中度狭窄98例(中度组)、重度狭窄89例(重度组)、闭塞68例(闭塞组)。分别测量各组颈总动脉收缩期血流峰值(PSV)、舒张末期血流速度(EDV)、阻力指数(RI)、血管内径(D)、血流量(BFV),并分析各指标与颈内动脉狭窄程度的关系。结果重度组和闭塞组患侧颈总动脉PSV、EDV、BFV明显低于同组健侧颈总动脉,RI明显高于同组健侧颈总动脉(P均0.05)。重度组和闭塞组患侧颈总动脉PSV、EDV、BFV明显低于中度组患侧颈总动脉,RI明显高于中度组患侧颈总动脉(P均0.05)。相关分析显示,颈内动脉狭窄程度与颈总动脉EDV、BFV呈负相关关系(r分别为-0.893、-0.723,P均0.01),与颈总动脉RI呈正相关关系(r=0.853,P0.05),与颈总动脉PSV、D无明显相关性(r分别为0.536、0.324,P均0.05)。结论颈总动脉EDV、BFV可用于评价颈内动脉狭窄程度,尤其是颈内动脉闭塞。
[Abstract]:Objective to evaluate the value of common carotid artery hemodynamic parameters in judging the degree of internal carotid artery stenosis. Methods 255 cases of unilateral internal carotid artery stenosis or occlusion without stenosis or slight stenosis of the contralateral artery with the same name were selected. According to the degree of internal carotid artery stenosis, 98 cases of internal carotid artery stenosis (moderate group), 89 cases of severe stenosis (severe group) and 68 cases of occlusion (occlusion group) were divided into two groups. The blood flow velocity, resistance index (RI), blood flow volume (BFV) and blood flow volume (BFV) were analyzed. Results the BFV of common carotid artery in severe group and occlusion group was significantly lower than that in the control group, and the RI of common carotid artery in normal side was significantly higher than that in control group. In the same group, the normal common carotid artery (P < 0.05), the common carotid artery (PSV) EDV (BFV) in the severe group and the occlusion group (P < 0.05) were significantly lower than those in the moderate group (P < 0.05). There was a negative correlation between the degree of stenosis of internal carotid artery and EDVV BFV of common carotid artery (r = -0.893t -0.723), a positive correlation with RI of common carotid artery (r = 0.853N, P 0.05), and no significant correlation with common carotid artery (PSV) D, respectively (r = 0.5360.3244P = 0.050.Conclusion EDV BFV of common carotid artery can be used to evaluate common carotid artery. Degree of stenosis of internal carotid artery, Especially internal carotid artery occlusion.
