124例脑梗死CT表现与临床分析及早期诊断

目的：分析脑梗死的CT及临床表现，探讨CT对脑梗死的诊断价值，提高脑梗死早期诊断水平。方法：对我院收治的经CT确诊的124例脑梗死患者的临床特点及CT表现进行分析。结果：缺血性梗塞的形态呈圆形、类圆形、椭圆形或条索状，颞叶病灶多呈片状不规则低密度，占位表现轻微；出血性梗塞多位于额、顶叶，表现为扇形或不规则低密度区内出现斑点状高密度，有明显占位表现。结论：高血压、糖尿病与缺血性脑卒中的发生有密切关系．是重要的危险因素，且预后差。脑梗死发病的部位多为基底节区，以下依次为脑叶、小脑、脑干，说明主要由穿通支脑动脉供血的基底节区是缺血性病变的好发部位。及时的CT检查并结合临床表现，选择在恰当的时间进行溶栓、介入等治疗。可降低其致残率和死亡率。

Analysis of 124 Cases Cerebral Infarction Clinical Manifestation on CT

Objective To analyze CT images and clinical manifestation of cerebral infarction and discuss diagnostic value to improve early diagnosis. Methods 124 cerebral infarction cases which have suffered in our hospital were researched. Results The shapes of ischemic infarct were round, oval and streak, but the shapes of temporal lobe focus were mostly lamellar irregular, low density and little occupying-effect. Hemorrhagic infarcts of forehead and parietal lobe were fanlike or irregular and low density area with mottling high density. Conclusion Cerebral arterial thrombosis was relative closely to hypertension and diabetes mellitus. The cerebral infarctions almost occur in basal ganglia. Lobe of brain, cerebellum and brainstem is key part so that explains basal ganglia of penetrating branch cerebral arteries were high site of ischemic cerebral artery disease Mutilation rate and mortality may be reduced by CT examine in time and linked to clinical thrombolysis and intervention treatment.
