目的研究颈动脉粥样斑块性状和部位与复发性脑梗死的关系。方法采用彩色多普勒血流成像技术对105例复发性脑梗死(复发组)、80例初发性脑梗死(初发组)和95非缺血性心脑血管病(对照组)患者进行检测,观察颈动脉粥样硬化斑块的数目及部位,并测量血管壁的厚度和斑块的大小及厚度。结果复发组颈动脉粥样斑块发生率为67.6%高于初发组及对照组,双侧颈动脉受累及一条血管多个斑块及各型斑块并存多见,颈总动脉(CCA)分叉处发生率最高。软斑及合并溃疡的混合斑是脑梗死主要的栓子来源之一。结论颈动脉不稳定性粥样斑块的存在是复发性脑梗死的危险因素。颈动脉超声检查对复发性脑梗死有重要的意义。
Objective To study the relationship between carotid atherosclerotic plaque characteristics and location and recurrent cerebral infarction. Methods Color Doppler flow imaging was used in 105 patients with recurrent cerebral infarction (recurrent group), 80 patients with primary cerebral infarction (initial group) and 95 non-ischemic cardiocerebral vascular disease (control group) The number and location of carotid atherosclerotic plaque were detected and observed. The thickness of vascular wall and the size and thickness of plaque were measured. Results The incidence of carotid artery atherosclerotic plaques in recurrence group was 67.6% higher than that in primary and control groups. Multiple carotid arteries involved and multiple plaques of one vessel coexisted. Common carotid artery (CCA) The highest incidence of bifurcation. Bleeding spots with soft spots and ulcers are one of the major sources of emboli in cerebral infarction. Conclusion The presence of carotid instability plaque is a risk factor for recurrent cerebral infarction. Carotid ultrasound examination of recurrent cerebral infarction has important significance.
