目的探讨大面积脑梗死患者的CT诊断方法及效果。方法对河南省固始县公疗医院收治的75例大面积脑梗死患者进行CT检查,分析检查结果。结果本组大部分患者在2h内就诊,对6h后入院就诊的患者多次CT检查结果显示,随发病时间延长患者脑组织水肿逐渐加重,梗死区域脑组织密度不断下降。本组CT扫描显示脑半球区域梗死患者21例,脑枕叶区域梗死患者16例,颞、顶叶区域梗死患者12例,额、叶区域梗死患者11例,脑基底区域梗死患者8例,顶叶、丘脑区域梗死患者7例。患者CT影像表现为脑中动脉呈条线状高密度分布且包含钙化、梗死中线结构向对侧移动、梗死呈大片状且片状边界模糊低密度区或梗塞分布呈双侧显示。结论大面积脑梗死与脑出血在临床症状上具有一定相似性,易出现误诊,采用CT诊断能够准确鉴别和区分,临床效果显著,应用价值较高。
Objective To investigate the CT diagnosis and its effect in patients with large area cerebral infarction. Methods 75 patients with large area cerebral infarction admitted to Gushi County Public Hospital of Henan Province underwent CT examination and the results of the examination were analyzed. Results Most of the patients in this group were treated within 2 hours. The CT findings of patients admitted to hospital after 6 hours showed that the edema of brain tissue gradually increased and the density of brain tissue in infarcted area decreased continuously with the extension of time. This group of CT scans showed cerebral infarction patients in 21 cases, brain occipital lobe infarction in 16 cases, temporal, parietal infarction in 12 cases, frontal and lobar infarction in 11 cases, basal infarction in 8 patients, top 7 cases of infarction in the leaves and thalamus. The CT images of the patients showed a high density distribution of the middle cerebral artery in the form of lines and lines, which included calcification. The midline structure of the infarction moved to the opposite side. The infarct showed a large patch and the blurred border of the flaky border or the distribution of the infarction showed bilateral display. Conclusion Large area cerebral infarction and cerebral hemorrhage have some similarities in clinical symptoms and are prone to misdiagnosis. CT diagnosis can identify and distinguish accurately, and the clinical effect is significant and the application value is higher.
