2019-03-29 杨中华 脑血管病及重症文献导读

67岁,男性,因为左侧上肢无力1h就诊。

67岁,男性,因为左侧上肢无力1h就诊。

NIHSS 2分,拒绝静脉溶栓。

既往史:高血压和高脂血症。

头颈 CTA 显示右侧颈内动脉后壁发出层状充盈缺损,伴30-50%狭窄。轴位 CTA 证实为腔内隔膜,符合颈动脉蹼的表现,无钙化,也没有附着的血栓(下图):

脑MRI 显示右侧额叶急性梗死,累及右侧运动皮层(下图),同时可见同一动脉供血区陈旧性脑栓塞性梗死:

对侧颈内动脉、颅内动脉未见动脉闭塞、狭窄或严重异常。经胸超声和心电监测未见异常。心电图监测未见房颤

开始给予阿司匹林100mg,每天一次。11个月后再发左侧面部下垂,左上肢无力和构音障碍。

头 MRI 显示上一次梗死灶旁新发梗死(下图):

脑CTA显示右侧 MCA M2段新发闭塞。颈部 CTA 显示右侧颈内动脉狭窄,狭窄程度和腔内病变的形态与前一次相比没有变化。

DSA 进一步证实为颈动脉蹼,患者随后进行了血管内治疗,右侧颈内动脉置入自膨支架,治疗后狭窄明显好转:

患者症状完全缓解,出院给予双抗治疗3个月,以后长期阿司匹林单抗治疗。
