目的探讨脑梗死TOAST分型与影像学分型的关系。方法选择我院2011年1月至2012年6月收治的200例急性脑梗死患者分别进行TOAST分型与影像学分型诊断,比较两种分型的相关性。结果 62例大动脉粥样硬化患者中,57例(91.94%)为腔梗,5例(8.06%)为大梗塞,较多发生于顶叶、颞叶与额叶,患者发病时伴有意识障碍。38例心源性栓塞患者中36例(94.74%)为大梗塞,2例(5.26%)为腔梗。57例小动脉病患者中,51例(89.47%)为小梗塞,4例(7.02%)为阴性,2例(3.51%)为大梗塞。43例病因不明、其他病因或混合病因患者中,36例(83.72%)为腔梗,3例(6.98%)为大梗塞,3例(6.98%)为小梗塞,1例(2.33%)为阴性。结论脑梗死患者TOAST分型与影像学分型准确性高,对应性良好,具有较高的可信度。
Objective To explore the relationship between TOAST classification and imaging classification of cerebral infarction. Methods Totally 200 acute cerebral infarction patients admitted to our hospital from January 2011 to June 2012 were diagnosed by TOAST and imaging respectively. The correlation between the two subtypes was compared. Results Of the 62 patients with atherosclerosis, 57 (91.94%) had a luminal infarction and 5 (8.06%) had a large infarct, which occurred mostly in the parietal lobe, temporal lobe and frontal lobe. Thirty-six patients (94.74%) had major infarction in 38 patients with cardiac embolism, and 2 patients (5.26%) had infarction. Of 57 patients with arterioles, 51 (89.47%) were small infarcts, 4 (7.02%) were negative, and 2 (3.51%) were large infarcts. Of the 43 patients with unknown etiology, 36 (83.72%) had infarction, 3 (6.98%) had infarction, 3 (6.98%) had small infarction and 1 negative. Conclusion TOAST classification and imaging accuracy of cerebral infarction patients with high accuracy, good correspondence, with high credibility.
