孤立性动眼神经麻痹的临床DSA评价

The Isolated Third Nerve Palsy: Clinical and DSA Evaluation

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 significance and usefulness of DSA in diagnosing the cause of isolated third nerve palsy by analyzing the clinical manifestations and DSA findings in 260 patients.Materials and Methods The clinical manifestations and cerebral DSA findings in 260 patients were analyzed.Results About 7% of total cerebral aneurysms could cause isolated third nerve palsy. And of the aneurysms of posterior communicating artery, which were most likely to cause the disease, up to 73% would result in isolated third nerve palsy. DSA could fully and actually demonstrate the features of the aneurysms causing isolated third nerve palsy.Conclusion For patients with isolated third nerve palsy, DSA should be performed in order to exclude the brain aneurysms.
