【摘要】 目的　研究出血性脑梗死的病因、影像和临床特征。方法　回顾 3年中 3 41例住院非腔隙性脑梗死的临床资料。分析 3 0例 HI的病因、临床和影像改变。结果　HI发病率占同期脑梗死的 8.8%。脑栓塞为其主要病因 ,占 70 % ,并以心源性栓塞为主。HI最早发生在脑梗死后 2 4 h内。最长时间为 3 0 d。 2 6例发生在 MCA分布区。有血肿型和非血肿型之分 ( 1 8例和 1 2例 )。结论　脑栓塞和大面积脑梗死患者症状加重或治疗后无明显好转者 ,建议发病后 1到 2周内进行影像学复查。更多还原

【Abstract】 Objective To study the cerebral hemorrhagic infarction (HI) causes, imaging and clinical characteristics.Methods The causes, imaging and clinical syndroms in 30 patients with HI (from 341 cases of cerebral infarction treated during 1998 2000) were analysed.Results HI were detected in 8.8% cases of 341 patients. The most frequent causes of HI were cerebral embolism (70%), particularly cardiogenic. The earliest HI were detected within 24 h after onset of disease and the latest by 30th day. HI in 26 patients occurred in cerebral region supplied by MCA. HI might appear in hematomic and nonhematomic form (18 and 12).Conclusion To reexamine imaging in the first and the second week of patients with cerebral embolism or massive infarction if the clinical syndrom progresses or no improvement is found.更多还原
