【摘要】：目的分析TIA及TIA形式的脑梗死的临床特点,探索其临床相关因素。方法回顾性分析83例初步诊断为TIA并在症状首发后24 h内行常规MRI及DWI检查的患者,发病1周内行颈部动脉血管彩超、TCD。记录发病后7 d内的临床转归。根据DWI结果分为DWI+组及DWI-组,确定DWI阳性率。比较DWI+组及DWI-组临床特征差别。分析两组患者动脉粥样硬化斑块的部位、性质、数量及颅内外血管狭窄的部位、程度。结果DWI阳性率为36.1%。DWI阳性与动脉粥样硬化相关(P=0.03),与颈部动脉动脉粥样硬化斑块数目相关(P=0.04),TIA症状首发后7 d内,30.0%DWI+组患者TIA症状反复发作或表现为临床症状持续存在,高于DWI-组(22.6%)。结论临床表现为TIA的病例大于1/3急性期已经形成了脑梗死,动脉粥样硬化斑块数量越多,DWI阳性的可能性越大,DWI+的患者7 d内更易进展。
[Abstract]:Objective to analyze the clinical features of cerebral infarction in the form of TIA and TIA. Methods Eighty-three patients with TIA who were diagnosed as TIA and performed routine MRI and DWI examination within 24 hours after the initial symptom were retrospectively analyzed. The clinical outcome was recorded within 7 days after onset. According to the results of DWI, the patients were divided into DWI group and DWI- group. To determine the positive rate of DWI. To compare the clinical characteristics between DWI group and DWI- group. To analyze the location, nature, quantity and location of intracranial and extracranial vascular stenosis of atherosclerotic plaques in the two groups. Results the positive rate of DWI was 36.1%. The positive rate of DWI was correlated with atherosclerosis and the number of carotid atherosclerotic plaques. Within 7 days after the onset of TIA symptoms, the patients in the DWI group had repeated attacks of TIA symptoms or persistent clinical symptoms. Conclusion the clinical manifestation of TIA is that cerebral infarction has been formed in more than 1/3 acute stage, and the more atherosclerotic plaques are, the more likely it is to be positive on DWI. Patients with DWI were more likely to progress within 7 days.

【正文快照】： 短暂性脑缺血发作(TIA)是临床常见的缺血性脑血管病,是预示也是防治缺血性脑血管病病情恶化、发展为脑梗死的关键时期。DWI(弥散加权成像)技术能够区分急性和慢性缺血,被推荐为TIA首选的脑成像诊断方式[1~3]。本研究根据DWI结果将患者分为TIA与TIA形式的脑梗死组,分析其相关因
