脑供血动脉闭塞与颅内动脉瘤形成关系的初步分析

目的初步评价脑供血动脉闭塞与颅内动脉瘤发生之间的关系。方法本研究分析了8例脑供血动脉闭塞伴有颅内动脉瘤患者的临床资料。结果8例患者中单侧颈内动脉闭塞7例，双侧颈内动脉及一侧椎动脉同时闭塞1例。8例患者共检出动脉瘤11枚，多发动脉瘤患者3例，所有动脉瘤均位于Willis环，其中9枚动脉瘤采用了血管内栓塞治疗，致密栓塞5例，本组病例未发生技术相关并发症。I临床随访9个月～14年，提示所有患者出院后病情稳定，无新发神经功能缺损。结论脑供血动脉闭塞后代偿血管的血流动力学变化与颅内动脉瘤的生成密切相关。

Correlation of cerebral artery occlusion for intracranial aneurysms formation

Objective To evaluate the correlation of cerebral artery occlusion for intracranial aneurysms formation preliminarily. Methods The clinical data of 8 patients with cerebral artery occlusion and intraeranial aneurysms, were retrospectively collected and analyzed. Results Seven of 8 cases were with unilateral carotid artery occlusion, while 1 case with bilateral carotid and unilateral vertebral artery occlusion. Eleven aneurysms were revealed in total. Three patients harbored multiple aneurysms. All these aneurysms located in the willis circle, 9 of which were treated endovascularly resulting in 5 complete occlusions. There was no procedure related complication in this series. There was no neurological deterioration during 9 - month to 14-year clinical follow-up. Conclusion The hemodynamic changes following cerebral artery occlusion may lead to intracranial aneurysm formation.
