摘要 目的:通过CT灌注成像对不同程度颈内动脉狭窄脑灌注进行评价,为颈内动脉狭窄脑缺血的临床诊断及治疗提供依据。方法:收集48例单侧颈内动脉狭窄患者,根据狭窄程度分组,中度组10例;重度组16例,闭塞22例。观察不同程度颈内动脉狭窄患者脑组织不同部位脑灌注状态。结果:rTS:闭塞患者脑颞叶、基底节、前分水岭灰质、前分水岭白质、后分水岭灰质、后分水岭白质较中度狭窄患者明显延长;闭塞患者前分水岭灰质、前分水岭白质、后分水岭白质较重度狭窄患者明显延长。rTTP:闭塞患者脑颞叶、基底节、前分水岭白质、后分水岭灰质较中度狭窄患者明显延长;闭塞患者基底节、前分水岭灰质、前分水岭白质较重度狭窄患者明显延长。结论:颈内动脉狭窄患者脑组织脑灌注状态可通过CTP进行有效的评价,随着颈内动脉狭窄程度的增加,灌注异常也明显增加,而以前、后分水岭区多见,尤其是后分水岭区白质最明显。
