摘要
目的研究眼外肌麻痹对以眩晕为主诉的椎-基底动脉系统缺血性脑血管病诊断价值。方法 75例以眩晕为主诉、头部CT排除出血的椎-基底动脉系统急性缺血性脑血管病患者,所有病例均做头磁共振平扫(MRI)、头磁共振动脉成像(MRA)、脑干听觉诱发电位(BAEP)、体感诱发电位(SEP)检查。结果入组75例中眼外肌麻痹45例,无眼外肌麻痹30例。眼外肌麻痹45例中入院和出院时眼外肌麻痹情况无变化者5例,考虑有先天斜视的可能而剔除。头MRI有梗死病灶57例(占81.4%),其脑干有病灶10例,检出眼外肌麻痹组9例,无眼外肌麻痹组1例,眼外肌麻痹对脑干有梗死灶者的敏感性为90%,可见脑干有梗死灶者易检出眼外肌麻痹(P<0.05)。结论对以眩晕为主诉的椎-基底动脉系统急性缺血性脑血管病患者眼外肌麻痹是一种便捷有效的临床检查方法。
Objective To investigate the diagnosis value of ophthalmoplegia externa for vertebral-basilar artery system acute ischemic cerebrovascular disease by the chief complaint of vertigo.Methods Seventy-five patients diagnosed as vertebral-basilar artery systema acute ischemic cerebrovascular disease and depleted hemorrhage by the chief complaint of vertigo were examined with magnetic resonance imaging（MRI）,magnetic resonance angiography（MRA）,brain-stem auditory evoked potential（BAEP）and sensory evoked potential（SEP）.Results There were 45 cases that had the symptom of ophthalmoplegia externa and 30 cases had not in all the 75 examples.The 5 cases in and out of hospital that had no changes in ophthalmoplegia externa among the 45 cases that had the symptom of ophthalmoplegia externa were rejected for the possibility of congenital strabotic.The 57 cases checked by MRI had focus of infarction and occupied 81.4% in all cases.There were 10 cases that had focus of infarction in brainstem,among them 9 cases had the symptom of ophthalmoplegia externa and 1 none.Its sensitivity was 90% and it was believed that ophthalmoplegia externais was more easily detected in brainstem infarction（P0.05）.Conclusion The examination of ophthalmoplegia externa is useful for auxiliary diagnosis of vertebral-basilar artery systema acute ischemic cerebrovascular disease by the chief complaint of vertigo.
