摘要
目的探讨大脑中动脉严重狭窄或闭塞患者临床与影像学特征。方法回顾性分析35例大脑中动脉中重度狭窄或闭塞患者的临床资料，并对其临床表现、MRA影像学特征进行分析。结果临床表现：35例患者均表现为偏瘫，其中面部和上下肢同时受累16例（45．7％），上下肢同时受累11例（31．4％），面部及上肢受累3例（8．6％），单纯面部受累2例（5，7％），面部及下肢受累2例（5．7％），单纯上肢受累1例（2．9％）。MRA影像学特征及脑梗死类型：29例（82．9％）患者表现为病变侧MCA中度以上狭窄，6例（17．1％）表现为MCA闭塞。30例（85．7％）表现为缺血性梗死灶，其中深部小梗死最为常见（53．3％），其次为交界区梗死（26．7％），皮层区域内脑梗死相对较少（20．0％）。结论偏瘫是大脑中动脉狭窄或闭塞患者常见的临床症状，主要表现为面部和上下肢同时受累；深部小梗死是影像学脑梗死常见的类型。
Objective To evaluate the clinical and imaging features and infarct pattern in patients with mid- die cerebral artery（MCA） stenosis and occlusion,to clarify its infarct pathogenesis. Methods 35 MCA moderate and severe stenosis or occlusion patients diagnosed by TCD were studied; the clinical and imaging features and infarct pat- tern were retrospectively analyzed. Results （ 1 ） Clinical features ： The clinical manifestations of 35 patients was hem- iplegia symptoms, in which 16 cases （45.7 % ） involved to the face, upper and lower limb, 11 cases （31.4% ） involved to the upper and lower limb,3 cases （ 8.6% ） involved to the facial and upper limb,2 cases （5.7 % ） involved only to the facial ,2 cases（5.7% ） involved to the facial and upper limb, 1 cases （2.9%） involved only to the upper limb. （2） MRA imaging characteristics and infarct pattern：29 cases（82.9% ） of patients with stenosis or occlusion showed moderate severe stenesis ,6 cases （ 17.1% ） showed MCA occlusion. 30 cases （85.7 % ） showed ischemic infarction, in which perforating artery infarction was the most common infarct pattern of middle cerebral artery stenosis or occlusive patients（53.3% ）,followed by water-shed infarct （26.7）%, pial infarct was ielatively small （20. 0% ）. Conclusion The hemiplegia was the most common clinical symptoms in patients with MCA stenosis and occlusion, and mainly involves to the face, upper and lower limb;The perforating artery infarction was the most common infarct pattern, and its infarct mechanism was an artery-to-artery embolism or hemodynamic abnormalities.
