【摘要】 目的研究颈动脉及颅内血管的功能状况,为缺血性脑卒中的预防及治疗提供依据。方法对110例缺血性脑卒中患者行眼底、颈动脉彩色多普勒超声、颅底大动脉经颅多普勒检查。结果眼底病变以高血压视网膜病变、糖尿病视网膜病变为主,分别占61.8%和25.5%;颈动脉超声异常率达84.5%,颅底大动脉经颅多普勒异常达71.8%。结论缺血性脑卒中患者易合并眼底病变和颈动脉、颅底大动脉异常改变。对颈动脉和颅内动脉的联合检查有助于评价患者侧支循环状况,早期进行眼底检查,有助于采取相应的干预措施,以减少其对视力的危害。更多还原

【Abstract】 Objective In order to provide evidence for prevention and treatment in ischemic stroke,Hemodynamics in intracranial arteries and carotid arteries were studied.Methods 110 patients with ischemic stroke were examined with the fundus、Color Dopple ultrasonography and transcranial Dopple(TCD).Results Hypertensive Retinopathy(61.8%) and Diabetic Retinopathy(25.5%) were dominant in all patients The abnormal rate were 84.5% and 71.8% respectively in carotids by Color Doppler ultrasonography and the changes of TCD.Conclusion It was helpful to evaluate collateral circulation that the examinations of carotids arteries and intracranial arteries were combined.It was an important index of condition of patients and prognosis in ischemic stroke,especially those with the early diagnosis of the changes of the fundus,providing objective data in preventing visual impairment.更多还原
