Abstract: This article reports a case of non-disabling acute ischemic stroke in which TCD microembolic monitoring revealed an “Embolic Shower”, and 7 T HR-MRI revealed unstable plaques in the M1 segment of the left middle cerebral artery. After dual antiplatelet therapy, intensive lipid-lowering, and intravenous fluid therapy, the patient’s condition stabilized. The diagnosis and treatment process of this case suggests that for patients with high-risk non-disabling acute ischemic stroke, the etiology and pathogenesis should be identified as soon as possible, and early individualized treatment is crucial for effectively preventing stroke recurrence.

Key words: High-risk non-disabling acute ischemic stroke; Intracranial atherosclerosis; Microembolic signal

摘要： 本文报道1例急性非致残性缺血性卒中患者的临床特点，该患者在进行TCD微栓子监测时发现“栓子雨”现象，7 T HR-MRI检查提示左侧大脑中动脉M1段存在不稳定斑块。患者经双联抗血小板、强化降脂、补液扩容治疗后病情稳定。本病例的诊疗经过提示，对于高危非致残性急性缺血性卒中患者，应尽早明确病因及发病机制，早期给予个体化治疗，以有效预防卒中复发。
