目的：探讨颅内巨大动脉瘤的临床表现及脑血管造影特征。材料和方法：对２０例颅内巨大动脉瘤患者的临床、病理及脑血管造影资料进行全面分析，探讨颅内巨大动脉瘤发生的部位与其临床表现之间的关系以及它们的脑血管造影特征。结果：颅内巨大动脉瘤一般瘤颈较宽，瘤腔内容易血栓形成。其占位效应可直接或间接的引起临床症状和体征。同一部位的巨大动脉瘤可能会有不同的临床表现，而不同部位的巨大动脉瘤可能会有相同的临床表现。结论：临床症状和体症对判断颅内巨大动脉瘤的发病部位没有特异性，脑血管造影对显示颅内巨大动脉瘤的部位和特征具有重要价值。
Objective: To investigate the clinical manifestations of intracranial giant aneurysms and the characteristics of cerebral angiography. MATERIALS AND METHODS: The clinical, pathological and cerebral angiographic data of 20 patients with giant intracranial aneurysm were analyzed comprehensively to explore the relationship between the location of intracranial giant aneurysms and their clinical manifestations and their characteristics of cerebral angiography. Results: Intracranial giant aneurysms generally wide neck, tumor cavity thrombosis easily. The placeholder effect can directly or indirectly cause clinical symptoms and signs. Huge aneurysms in the same area may have different clinical manifestations, whereas giant aneurysms in different sites may have the same clinical manifestations. Conclusion: The clinical symptoms and physical diseases are not specific for judging the location of intracranial giant aneurysms. Cerebral angiography is of great value in displaying the location and characteristics of intracranial giant aneurysms.
