目的探讨超早期大脑中动脉供血区大面积脑梗死临床特点与CT征象特征。方法分析20例超早期大脑中动脉供血区大面积脑梗死的临床表现及具有特点的CT征象。结果 20例超早期大脑中动脉供血区大面积脑梗死的患者临床表现为肢体瘫痪19例(95%),伴有头痛、恶心、呕吐等颅内高压症状18例(90%),有意识障碍17例(85%)。CT征象有大脑中动脉高密度征5例(25例),豆状核境界模糊2例(10%),岛皮质境界不清1例(5%),早期低密度改变2例(10%),脑沟变浅或消失4例(20%),梗死区点状出血1例(5%)。结论超早期大脑中动脉供血区大面积脑梗死患者临床症状突出,多具有CT征象。
Objective To investigate the clinical features and CT features of large area cerebral infarction in the early middle cerebral artery. Methods The clinical manifestations and CT features of 20 cases of large area cerebral infarction in the early middle cerebral artery were analyzed. Results Nineteen patients (95%) had limb paralysis in 20 cases of MCI with super-early middle cerebral artery occlusion, 18 cases (90%) had symptoms of intracranial hypertension such as headache, nausea and vomiting, with disturbance of consciousness Example (85%). There were 5 cases (25 cases) with CT signs of high cerebral infarction, 2 cases (10%) with fuzzy nucleus pulposus, 1 case (5%) with unclear border and 2 cases with early low density change (10% , Shallow sulcus or disappearance in 4 cases (20%), 1 case of infarction-like spot bleeding (5%). Conclusion The clinical symptoms of large area cerebral infarction in the early middle cerebral artery arterial blood supply area are prominent, and often have CT signs.
