目的明确大脑后动脉枕叶分支梗塞的临床特点。方法对１０２例枕叶梗塞病人进行病因、临床特征、ＣＴ、图形视觉诱发电位和视野检查。结果视觉症状是枕叶梗塞的主要临床症状，头晕、头痛、视物不清是枕叶梗塞的首发症状，以上症状恢复较快且完全。同向性偏盲是最常见的临床症状，持续时间长，恢复不理想。结论ＣＴ检查是枕叶梗塞最重要的诊断方法。图形视觉诱发电位异常改变对枕叶缺血性损伤非常敏感，波形稳定，所以图形诱发电位可做为枕叶梗塞临床监护、疗效观察的重要指标。
Objective To clarify the clinical features of posterior cerebral artery occlusion of the occipital lobe. Methods 102 cases of occipital lobe infarction patients etiology, clinical features, CT, visual evoked potentials and visual field examination. Results Visual symptoms were the main clinical symptoms of occipital lobe infarction. Dizziness, headache and blurred vision were the first symptoms of occipital infarction. The above symptoms recovered quickly and completely. Isotropic hemianopia is the most common clinical symptoms, long duration, recovery is not satisfactory. Conclusion CT examination is the most important diagnostic method of occipital infarction. Graphic visual evoked potential abnormalities in the occipital lobe ischemic injury is very sensitive, stable waveform, so the evoked potential of the occipital lobe can be used as clinical monitoring, an important indicator of the efficacy observed.
