摘要
目的 研究慢性脑供血不足患者的脑血流及颈动脉粥样硬化特点。方法 分别对100 例慢性脑供血不足患者和100例正常对照者及100例脑梗死患者行颈动脉彩色多普勒及经颅多普勒检查,并测量相关指标。结果 观察组颈动脉粥样斑块发生率为60%,内膜粗糙率为31%,颈动脉内膜中层厚度>1.00 mm者占24%,颈动脉狭窄率为23%,颅内血流异常率为60%,颅内血管狭窄率为16%,而正常对照组分别为18%,4%,4%,6%,8.1%,4.8%;脑梗死对照组分别为90%,62%,51%,45%,88.9%,50%,观察组与正常对照组比较有显著差异(P<0.01),脑梗死对照组与观察组比较也有显著差异(P<0.01)。结论 慢性脑供血不足是动脉粥样硬化过程的一个阶段,是缺血性脑卒中的预兆。
Objective To study the characters of cerebral blood flow and atherosclerosis in the patients with chronic cerebral circulation insufficiency (CCCI).Methods One hundred patients diagnosed as CCCI were assigned in test group,100 healthy people,in normal control group,and the other 100 patients diagnosed as cerebral infarction, in infarction control group.They were given carotid color Doppler examination and TCD to measure related indexes.Results In the test group, the incidence rates of carotid atherosclerosis spot,intima coarseness,middle intima thickness> 1.0 mm,carotid stenosis,abnormal intracranial artery blood flow and intracranial vascular stenosis were 60%,31%,24%,23%,60% and 16%,respectively.In the normal control group,the incidence rates were 18%,4%,4%,6%, 8.1% and 4.8% ,respectively.In the infarction control group,the incidence rates were 90%,62%,51%,45%, 88.9% and 50%,respectively.By analysis of statistics,there was significant difference between the test group and the normal control group (all, P < 0.01 ),and there was significant difference between the infarction control group and the test group (all , P < 0.01 ),also.Conclusions CCCI is the transition period in the process of atherosclerosis,and is the predicitive sign in the development of ischemic stroke.
