目的 了解不同程度及不同侧别的颈内动脉狭窄与认知功能障碍的相关性。方法 连续选取2017年6月至2018年8月期间,某医院神经内科接受CTA或DSA检查脑血管的患者,根据根据检查结果将研究对象分为狭窄组和对照组。对所有入组患者进行记忆测评量表+改良版WCST检查,记录测评得分,统计分析各组别患者的得分差异。总纳入65例,根据狭窄与否分为狭窄组(共34例)和对照组(共31例),根据狭窄程度将狭窄组分为轻度狭窄组(共15例)和中重度狭窄组(共19例),根据侧别将狭窄组分为左侧狭窄组(24例)和右侧狭窄组(10例)。结果 狭窄组与对照组记忆及执行能力均显著受损,差异有统计学意义(P <0.05)。狭窄程度及狭窄侧别与记忆及执行能力无相关性,差异均无统计学意义(P> 0.05)。结论 颈内动脉狭窄显著影响患者以记忆、执行能力为代表的认知功能,但狭窄严重程度及狭窄侧别与认知功能无关。 相似文献

老年后循环缺血患者单侧椎动脉优势现象研究 总被引:2,自引:1,他引:1
目的探讨单侧椎动脉优势现象在老年后循环缺血(posterior circulation ischemia,PCI)发病中的意义。方法选择PCI及老年前循环脑卒中患者229例,根据诊断分为老年PCI组(老年组)91例,中年PCI组(中年组)68例,老年前循环脑卒中患者(前循环组)70例。通过全脑数字减影血管造影术对比检测一侧椎动脉优势现象分布差异,分析椎动脉优势与PCI的相互关联,及二者的优势比。结果老年组椎动脉优势52例(57.1%),中年组26例(38.2%),前循环组22例(31.4%),老年组椎动脉优势现象发生率明显高于中年组和前循环组,差异有统计学意义(P<0.05,P<0.01)。老年组有单侧椎动脉优势的危险较中年组和前循环组明显增高(OR=2.154,95%CI:1.134~4.091;OR=2.909,95%CI:1.513~5.592)。结论单侧椎动脉优势现象是老年PCI常见的血管变异,与老年PCI间存在明显关联。 相似文献

目的探讨动脉粥样硬化性前循环短暂性脑缺血发作(TIA)患者中,动脉狭窄位置和狭窄程度与ABCD2评分的相关性。方法选择南京卒中注册系统中,接受数字减影血管造影(DSA)检查的前循环动脉粥样硬化性TIA患者1 51例进行ABCD2评分,根据ABCD2评分分值分为3组:低危组60例,中危组64例,高危组27例。分析患者脑血管形态学特点与各组的关系。结果 DSA显示,151例患者中,25例为正常血管,126例血管狭窄的患者检出216处狭窄或闭塞性病变。3组患者血管狭窄位置的分布差异无统计学意义(P>0.05);在症状相关侧大血管中,低危组患者正常血管的比例明显高于高危组,轻度狭窄的比例明显高于中危组和高危组,重度狭窄及闭塞的比例明显低于中危组和高危组,差异有统计学意义(P<0.05);在非症状相关侧大血管中,低危组患者正常血管的比例明显高于中危组和高危组,高危组患者中度狭窄的比例明显高于低危组和中危组,差异有统计学意义(P<0.05)。有症状和无症状侧血管的管腔狭窄程度随ABCD2评分的增高而表现出升高趋势(P<0.01)。结论前循环TIA患者的ABCD2评分能够反映患者前循环血管的狭窄程度。ABCD2评分高的前循环TIA患者应重视血管形态学检查。 相似文献

颈动脉球囊扩张支架置入术后持续性低血压危险因素分析 总被引:2,自引:0,他引:2
目的探讨颈动脉球囊扩张支架置入(CAAS)术后发生持续性低血压的危险因素。方法收集CAAS术患者177例资料,分析术后发生持续性低血压的危险因素。结果 177例中,出现持续性低血压92例。单因素分析提示,球囊直径、球囊长度、扩张次数、扩张持续时间、扩张压力、双侧颈动脉支架与术后发生持续性低血压有关(P<0.05)。Logistic回归Forward LR法分析提示,双侧颈动脉支架、球囊扩张持续时间≥5s、球囊扩张压力>8atm是发生术后持续性低血压的独立危险因素。结论双侧颈动脉支架置入、球囊扩张压力>8atm、扩张持续时间≥5s的患者术后易出现持续性低血压。 相似文献

缺血性脑血管病患者颈内动脉颅外段血管折曲的影响因素分析 总被引:1,自引:1,他引:0
目的 探讨缺血性脑血管病患者颈内动脉颅外段血管折曲的影响因素. 方法 选择行DSA检查的334例缺血性脑血管病患者,根据颈内动脉颅外段血管走行分为血管折曲组(血管成角小于90°定义为血管折曲,110例)和血管无折曲组(血管成角大于90°或盘曲成环状定义为血管无折曲,224例),根据患者年龄分为青年组(18~45岁)、中年组(46~64岁)和老年组(≥65岁).对于可能影响患者颈内动脉颅外段血管折曲的影响因素,如性别、年龄、身高、颈动脉狭窄程度和脑血管病危险因素等进行统计学分析. 结果 单因素分析发现,患者年龄、高血压病史、吸烟史、酗酒史、身高、性别比例在血管折曲组和血管无折曲组中差异有统计学意义(P<0.05);logistic回归分析显示,高血压病史(OR=2.546,95%CI:1.376~4.712,P=0.003)、年龄(以18~45岁为参照组,46~64岁组OR=2.610,95%CI:1.056~6.452,P=0.038;≥65岁组OR=2.929,95%CI:1.159~7.401,P=0.023)与患者颈内动脉颅外段血管折曲有明显相关性. 结论 高血压病史和年龄是缺血性脑血管病患者颈内动脉颅外段血管折曲的重要影响因素.Abstract: Objective To investigate the influencing factors of kinking of extracranial internal carotid artery (EICA) in patients with transient ischemic attack. Methods Three hundred and thirty-four patients with ischemic cerebrovascular disease performed digital subtraction angiography (DSA) were chosen; they were divided into 2 groups according to vascular morphology through DSA detection: kinking group (angulation smaller than 90°, n=110) and non-kinking group (angulation larger than 90°, n=224). According to the age, the patients were divided into youth group (18-45 years old),middle age group (46-64 years old) and elderly group (older than 65 years old). The influencing factors which may be related to the kinking of EICA, including gender, age, height and stenosis degree, and the risk factors for cerebrovascular diseases were statistically analyzed. Results Univariate analysis found that the kinking group and non-kinking group on the ratio of age, gender, height, and histories of hypertension, smoking and drinking were significantly different (P<0.05). Multiple logistic regression analysis showed that the kinking of EICA was obviously correlated to the history of hypertension (OR=2.546, 95% CI: 1.376-4.712, P=0.003) and age (taking youth group as reference group, middle age group:OR=2.610, 95% CI: 1.056-6.452, P=0.038, elderly group: OR=2.929, 95% CI: 1.159-7.401, P=0.023).Conclusion The history of hypertension and age are identified as independent predictors for kinking of EICA in patients with ischemic cerebrovascular diseases. 相似文献

Objective To investigate the incidence,distribution patterns,and influencing factors of cerebral microbleed (CMB) in Chinese adult patients with moyamoya disease.Methods Thirty consecutive patients with moyamoya disease confirmed by digital subtraction angiography from the Nanking Stroke Registry Program were included.All patients performed conventional MRI sequences (3.0 T) and susceptibility-weighted imaging.The clinical data,such as medical history,systolic blood pressure,diastolic blood pressure,mean arterial pressure,and white matter lesions were collected.Their fasting blood glucose levels and fibrinogen levels were detected.The numbers of CMB lesion,distribution information,and their relationship with various clinical parameters in patients with moyamoya disease were analyzed.Results Among the 30 subjects included,14 CMBs were detected in 10 patients from 11 hemispheres.The distribution of the lesions was mainly in deep brains (71.4%),especially in the periventricular white matter (50.0%).There was no statistical difference in age,gender,hemorrhage symptoms,blood pressure,white mater lesions,and plasma fibrinogen levels between the CMB positive group and CMB negative group.However,the fasting blood glucose levels in the former was significantly higher than those in the latter (8.0 ± 4.1 mmol/Lvs.4.8 ± 0.4 mmol/L;P =0.035).Multivariate regression analysis showed that the increased fasting blood glucose level was an independent risk factor for the occurrence of CMBs in adult patients with moyamoya disease (OR = 10.992,95% CI 1.325-91.218;P=0.026).Conclusions The CMB lesions are susceptible to Chinese adult patients with moyamoya disease in deep brains,especially in the periventricular white matter.The fasting blood glucose level may influence the incidence of CMBs in patients with moyamoya disease. 相似文献
