【摘要】 目的 探讨通过彩色多勒普超声检测颈动脉血流,来分析颈动脉病变与脑梗塞的关系。方法 本研究共有脑梗塞患者52例,男35例,女17例,左半球梗塞20例,右半球梗塞15例,双侧梗塞17例,正常对照组15例。并将检测颈总动脉、颈内动脉、椎动脉的结果,分成单侧梗塞组,双侧梗塞组及正常对照组进行统计分析。结果 脑梗塞患者颈部各动脉的阻力指数均与正常对照组比较有显著差异,而单侧脑梗与双侧脑梗组比较无明显差异。结论 颅外段颈动脉阻力指数的升高,与脑梗塞的发生密切相关,提示脑梗塞颅内血供减少,血管床阻力升高,但它不能反映梗塞的部位、范围及程度,不能对脑梗塞作出定位诊断。更多还原

【Abstract】 Purpose Subject to analyse the relationship of carotid artery disaese and cerebral infarction with color Doppler ultrasound examing carotid artery blood flow. Methods Fifty - two patients with cerebral infarction were detected by ultrasound (male 35 cases,female 17 cases) .There were left side infarction in 20 cases,right side infarction in15 cases,bilateral infarction in17 cases,and 15cases as normal. According to the conclusion of detecting common carotid artery, intracarotid artery and vertebra artery, it is divided into three groups (unilateral,bilateral,normal) to analysis with statistics. Results The resistance index of carotid artery in the patients with cerebral infarction has remarkable difference comparing with the normal, the unilateral group have no difference comparing with the bilateral group. Conclusion The raising of RI in the extercranial carotid artery is closely related with the occuring of cerebral infarction, it promotes that the blood flow in brain is reduced and the resistance of blood bed is raised in patients with cerebral infarction. But it can t reflect the site,scope and degree of infarction ,and it also can’t diagnose cerebral infarction directly.更多还原
