进展性缺血性卒中(SIP)是临床经常遇到的难题,发病率占缺血性脑卒中的9.8%～42.0%[1,2],使脑卒中病死率增加4倍以上,是死亡的独立预测因子。颈动脉粥样硬化狭窄是缺血性脑卒中的重要危险因素之一,而与卒中进展性的关系研究尚少。本研究通过对颈部血管彩色多普勒的检查,探讨颅内 Progressive ischemic stroke (SIP) is a common clinical problem that accounts for 9.8% -42.0% of ischemic strokes [1,2], leading to a more than 4-fold increase in stroke mortality and death Independent predictors. Carotid atherosclerosis is one of the most important risk factors for ischemic stroke, but there is little research on its relationship with the progress of stroke. In this study, through the examination of color Doppler of the blood vessels in the neck, explore the intracranial
