目的分析DWI以及大动脉粥样斑块形成是否有助于TIA预后的风险判断。方法收集荣成市人民医院TIA发作入院患者343例。其中339例患者行DWI检查;所有的患者均行TIA发作后颈部大动脉超声检查,并跟踪随访3个月。分别在TIA发作后的第1周以及第3个月评估检查。结果DWI的阳性率是40%(136例),患大动脉粥样斑块形成患者67例(20%),27例(8%)有房颤史。其中DWI检查阳性患者多伴随偏侧肢体障碍;TIA发病时间大于60min;大动脉粥样斑块形成。随访期间,5例(1.5%)患者在TIA后1周内有大中风发作。10例(2.9%)在3月内有一次大中风。9例TIA后卒中患者早期检查伴有DWI阳性发现。ABCD2评分及DWI的阳性发现与7d以及3个月内的卒中风险增加密切相关。在3个月时,ABCD2评分>4分,DWI的阳性表现、以及大动脉粥样硬化均为TIA发作后卒中的独立危险因素。而房颤未证实与此有关。结论DWI、颈部大动脉粥样斑块形成结合ABCD2评分可以提高TIA后卒中的风险预测。
Objective To analyze whether risk assessment of DWI and atherosclerotic plaque contribute to the prognosis of TIA. Methods 343 patients admitted to Tiantong People’s Hospital of Rongcheng City were enrolled. Among them, 339 patients underwent DWI examination. All the patients underwent ultrasound examination of cervical aorta after TIA onset and were followed up for 3 months. In the first week after the onset of TIA and the first 3 months to assess the assessment. Results The positive rate of DWI was 40% (136 cases), 67 cases (20%) had major atherosclerotic plaque, and 27 cases (8%) had atrial fibrillation history. The DWI positive patients were mostly accompanied by unilateral limb disorders; TIA onset time greater than 60min; atherosclerotic plaque formation. During follow-up, 5 patients (1.5%) had a stroke within one week of TIA. Ten patients (2.9%) had a major stroke in March. 9 cases of TIA post stroke patients with early detection of DWI positive findings. A positive ABCD2 score and DWI findings were associated with an increased risk of stroke at 7 and 3 months. ABCD2 score> 4 at 3 months, positive findings of DWI, and atherosclerosis were all independent risk factors for stroke after TIA. Atrial fibrillation has not been confirmed with this. Conclusions DWI, the formation of aortic atherosclerotic plaques combined with ABCD2 score can improve the risk prediction of stroke after TIA.
