目的 通过对 2 60例患者的临床及全脑血管造影分析 ,评价DSA在确诊孤立性动眼神经麻痹病因中的意义和作用。材料与方法 搜集 2 60例行全脑血管造影检查的病例 ,对其临床特征及DSA表现进行分析。结果 动脉瘤致孤立性动眼神经麻痹的发生率约占全部动脉瘤的 7%。后交通动脉瘤最易导致动眼神经麻痹 ,其发生率约占全部后交通动脉瘤的 73 %。DSA可以全面真实地反映致孤立性动眼神经麻痹的动脉瘤的特征。结论 对于孤立性动眼神经麻痹的患者 ,应行DSA检查除外动脉瘤的可能。
Objective To evaluate the clinical significance and the role of DSA in the etiology of isolated optic nerve palsy by clinical and total cerebral angiographic analysis of 260 patients. Materials and Methods260 cases of cerebral angiography were collected, and their clinical features and DSA findings were analyzed. Results Aneurysm-induced isolated oculomotor nerve paralysis accounted for about 7% of all aneurysms. Post-traffic artery aneurysm most likely to cause oculomotor nerve paralysis, the incidence of about 73% of all post-traffic artery aneurysms. DSA can completely and truly reflect the characteristics of aneurysm caused by isolated oculomotor palsy. Conclusion For patients with isolated oculomotor palsy, DSA should be performed to exclude aneurysms.
