本文对109例大脑中动脉（MCA）主干梗塞急性期的CT检查，治疗及病因进行了回顾性探讨，本病主要病因是栓塞，栓子来源主要为心房纤颤（AF）和心肌梗塞（AMI），其他病因亦不可忽视，如下肢深静脉炎、癌栓、颈内动脉血栓。本病的临床表现以偏瘫、凝视麻痹、各种失语和意识障碍为主。讨论了梗塞前CT的表现，指出本病引起出血性脑梗塞（HI）发病率较高，提出本病的急性期治疗以脱水，自由基清除剂、钙离子拮抗剂为主，不宜扩容，慎用溶栓。
In this paper, 109 cases of middle cerebral artery (MCA) infarction in the acute phase of CT examination, treatment and etiology of a retrospective study, the main etiology of this disease is embolism, the main source of emboli for atrial fibrillation (AF) and myocardial infarction (AMI ), Other causes can not be ignored, such as deep phlebitis, thrombus, carotid artery thrombosis. The clinical manifestations of the disease hemiparesis, staring paralysis, a variety of aphasia and disturbance of consciousness based. The performance of CT before infarction was discussed. The incidence of hemorrhagic cerebral infarction (HI) caused by this disease was pointed out. It was suggested that the acute phase of this disease should be treated with dehydration, free radical scavenger and calcium ion antagonist. Thrombolysis.
