目的:分析大面积脑梗塞的临床特征、影像学变化。方法:分析82例大面积脑梗塞的病因、临床特征、MRI及CT相关改变。结果:颈内动脉远端或大脑中动脉近端闭塞最多;额顶颞叶及内囊区梗塞最常见;伴有严重缺血性脑水肿及高颅压;梗塞后出血发生率较高;多合并高血压、冠心病、糖尿病、感染性疾病,易发生多脏器衰竭,病死率较高;脱水降颅压抗感染等综合治疗极其重要;MRI对急性期大面积脑梗塞有高度敏感性,能早期发现病灶及水肿的部位和范围。结论:大面积脑梗塞易发生脑水肿和脑疝而病情凶险;MRI是诊断急性期大面积脑梗塞最有价值的检查方法。
Objective: To analyze the clinical features and imaging changes of large area cerebral infarction. Methods: The etiology, clinical features, MRI and CT related changes of 82 cases of large area cerebral infarction were analyzed. Results: The distal occlusion of the internal carotid artery or the middle cerebral artery occured the most. The frontal temporal lobe and internal capsule infarction were the most common. Severe ischemic brain edema and high intracranial pressure were observed. The incidence of post-infarction bleeding was high. Combined with hypertension, coronary heart disease, diabetes, infectious diseases, prone to multiple organ failure, high mortality; dehydration and intracranial pressure anti-infection and other comprehensive treatment is extremely important; MRI acute acute cerebral infarction is highly sensitive, Early detection of lesions and edema of the site and scope. Conclusion: Large area cerebral infarction prone to cerebral edema and hernia and dangerous; MRI is the most valuable method of diagnosis of acute large area cerebral infarction.
