【摘要】 目的：探讨急性缺血性脑卒中(AIS)患者美国国立卫生研究院卒中量表(NIHSS)评分与颈动脉斑块内新生血管(IPN)的相关性。方法：选取2019年6月至2021年10月收治的73例AIS患者，采用NIHSS评分评估患者神经功能缺损程度，采用超声造影检查颈动脉IPN。分析AIS患者神经功能缺损NIHSS评分，颈动脉IPN分级，以及NIHSS评分与IPN的相关性。结果：神经功能缺损中重度组颈动脉IPNⅢ级+Ⅳ级的占比80.8%,高于神经功能缺损轻度组的54.7%,差异有统计学意义(P<0.05)。AIS患者颈动脉IPN与NIHSS评分呈正相关，r=0.267(P<0.05)。结论：AIS患者颈动脉IPN与神经功能缺损NIHSS评分相关联，颈动脉IPN分级越高，神经功能缺损越严重。更多还原

【Abstract】 Objective: To investigate the correlation between national institutes of health stroke scale(NIHSS) score and intraplaque neovascularization(IPN)within carotid in patients with acute ischemic stroke(AIS). Methods: Seventy-three AIS patients admitted from June 2019 to October 2021 were included, NIHSS score was used to assess the degree of neurological deficit and carotid IPN was evaluated by using contrast-enhanced ultrasound. The NIHSS score, carotid IPN grade, and the correlation between NIHSS score and IPN grade were analyzed in AIS patients. Results: The proportion of carotid IPN grade Ⅲ+Ⅳ in moderate and severe neurological deficit group was 80.8% higher than 54.7% in mild neurological deficit group, and the difference was statistically significant(P<0.05). Carotid IPN grade was positively associated with the NIHSS score in AIS patients, r= 0.267(P<0.05). Conclusion: Carotid IPN grade was associated with the neurological deficit NIHSS score in AIS patients, and the higher the carotid IPN grade is, the more serious the neurological deficit is.更多还原
