短暂性脑缺血发作ABCD3评分与供血动脉狭窄相关性的初步研究

目的探讨短暂性脑缺血发作(TIA)患者ABCD3评分与供血动脉狭窄分布的关系。方法前瞻性研究60例TIA患者入院时的ABCD3评分及头颈CT血管造影、颈部血管超声资料,根据ABCD3评分,分为≥4分组(中、高危组)和<4分组(低危组),根据头颈CTA和颈部血管超声的影像学结果,分为单只血管窄组(单独颈部血管或颅内血管);多只血管狭窄组(包括颈部血管和颅内血管);无血管狭窄组。评价ABCD3评分与脑供血动脉狭窄分布的相关性,初步探讨TIA预后评估的可能机制。结果≥4分组(中、高危组)患者动脉狭窄比例高于<4分组(低危组),以颅内血管狭窄为主,出现多支供血动脉狭窄病变比例高于低危组。结论 TIA患者颅内血管狭窄病变较颈部血管狭窄发生率高,ABCD3评分≥4分时颅内多支动脉狭窄发生率增高。

A Preliminary Study of the Correlation between Transient Ischemic Attack and Artery Stenosis with ABCD3 Score

Objective To explore the correlation between transient ischemic attack and artery stenosis with ABCD3 score. Methods Retrospective study of 35 cases of T1A patients admitted to hospital ABCD3 score and head CTA, carotid doplex ultrasound data, according to ABCD3 score, divided into〉4 grouping （in high-risk group） and group （low-risk group）, according to CTA of head and neck and vascular ultrasound imaging results, divided into single blood vessels narrow group （separate blood vessels of the neck or intracranial vessels）;single vascular stenosis group （including the neck vessels and intracranial blood vessels）; multivascular stenosis group. The evaluation ABCD3 score and cerebral artery stenosis distribution of correlation, and the possible mechanism of TIA prognosis. Result ≥ 4 grouping （high-risk group） in patients with intracranial arterial stenosis is higher than the 〈4 group （low-risk group）,multi-branch artery stenosis lesions proportion is also higher than the low-risk group. Conclusion Patients with TIA and intracranial vascular stenosis have the higher incidence of neck vascular stenosis. Meanwhile ABCD3 score ≥4 grouping has the higher incidence of intracranial artery stenosis.
