颈内动脉系统频发短暂性脑缺血发作51例分析

目的探讨颈内动脉系统频发短暂性脑缺血发作（TIA）的临床特征以及颈内动脉系统血管狭窄特点。方法回顾性分析51例颈内动脉系统频发TIA患者的临床资料。结果51例患者临床表现以一侧肢体无力E30例（59％）]最为常见，其余依次为肢体无力合并感觉症状[14例（27％）]、失语[4例（8％）]、感觉障碍[3例（6％）]。平均发作持续时间为23min；平均ABCD2评分为4．1分，4例患者在发作后1周内形成缺血性脑卒中。33例（65％）有颈内动脉系统血管狭窄，其中颅内动脉狭窄18例（35％），颅外动脉狭窄10例（20oA），颅内动脉、颅外动脉均有狭窄5例（10％）。轻度、中度、重度狭窄患者分别为7例（14％）、11例（22％）、15例（29％）。结论颈内动脉系统频发TIA以一侧肢体无力为主要临床表现。颈内动脉系统血管狭窄率为65％，且以颅内动脉狭窄为主。

Analysis of 51 patients with frequent transient ischemic attack related to internal carotid artery

Objective To investigate the clinical features of frequent transient ischemic attack （TIA） and the features of stenosis of internal carotid artery. Methods 51 patients with frequent TIA related to internal carotid artery were retrospectively analyzed. Results The most common clinical manifestation of all the 51 patients was unilateral weakness（59% ）, followed by unilateral weakness with sensory disturbance （27 %）, aphasia （ 8 % ）, sensory disturbance（6%）. The average duration time was 23 minutes. The mean ABCD2 score was 4.1. Four patients developed ischemic stroke within one week after attack. Vascular stenosis of internal carotid system occurred in 33（65%） patients, 18 （35 % ） patients with intracranial stenosis, 10 （20% ） patients with extracranial stenosis, 5 （ 10%） patients with both intracranial and extracranial stenosis. Patients with mild, moderate, severe stenosis were 7 （14%）, 11 （22%）, 15 （29 %）, respectively. Conclusions The most common clinical manifestation of frequent TIA related to internal carotid artery is unilateral weakness. The stenosis rate of internal carotid system is 65%, mainly intracranial.
