摘要
目的分析出血性脑梗死的发病率与发病机理,MRI与CT敏感性的比较.方法总结分析临床312例脑梗死患者中36例出血性梗死的影像学改变,临床表现和诊治结果.结果见36例梗死后出血,占同期脑梗死的11.21%,其中大面积脑梗死22例,占61.11%,心源性梗死7例,占19.44%,小脑梗死6例,占16.67%,死亡1例,占2.8%,既往有脑梗死史者6例,占16.67%,MRI发现少量梗死后出血的敏感性比CT高.给予适当的脱水、脑保护剂治疗,神经功能均有改善.结论大面积脑梗死、心源性脑梗死及小脑梗死易发生梗死后出血,小脑出血性梗死应积极脱水治疗,以防脑疝.
[Abstract] Objective To study the hemorrhagic infarction's(HI) incidence and principle and to contrast M RI 's sensitivity with the sensitivity of CT in diagnosing HI .Methods Among the 312 cerebral infarction patients 36 HI patients were founded.The 36 HI patients had been studied in picture changes, clinical expressions and the results of diagnosis and treatment. Results HI's incidence was 11.21% in our study .Among the 36 HI patients,22 patients were large area cerebral infarction, the imcidence was 61.11%. There were 7 patients' cerebral infarction caused by cardiac thrombus,the incidence was 19.44% , 6 patients had cerebral infarction history,the incidence was 16.67% , one died , six patients had cerebral infarction history , the ratio was 16.67% , MRI's sensitivity was higher than CT in diagnosing small cerebral infarction .After suitable treatment, most patients' neurological function improved .Conclusion Large area cerebral infarction, cerebral infarction caused by cardiac thrombus and cerebellar infarction can cause HI easily,cerebellar HI should be treated actively to prevent encephaloma.
