未破裂颅内动脉瘤的自然病史和一般处理

目的:对未破裂颅内动脉瘤的自然病史、破裂因素及一般处理原则做一综述。方法:查阅新近公开发表的中外文献对未破裂颅内动脉瘤的自然病史和一般处理进行综述。结果:颅内动脉瘤的破裂引起的蛛网膜下腔出血病死率很高,幸存者中也有一半患者遗留有不可逆的脑损害。10mm以下的动脉瘤破裂的危险性因素还不是十分清楚,但可以估计出每年有0.5%~2%的破裂率,不断生长的和大于10mm的动脉瘤破裂的几率会更大。结论:未破裂颅内动脉瘤自然病史及治疗中的危险因素的数据还不完整,处理方法仍有争议。

The Natural History and Management in Unruptured Intracranial Aneurysm

Objective:To review the recent studies on the natural history and causes of rupture and management of unruptured intracranial aneurysm.Methods:Reading and reviewing literatured related to the natural history and management of unruptured intracranial aneurysm.Results:The mortality of subarachnoid hemorrhage induced by rupture in intracranial aneurysm was high.Half of the survivor remained irreversible brain damage.The risk factors of rupture in aneurysm less than 10 mm was not clear.The rate of rupture in aneurysm was between 0.5% and 2%,which was higher in aneurysm with gradually growth or larger than 10 mm.Conclusion:The data about risk factors of history and management of unruptured intracranial aneurysm is still not complete.The methods on management is still argued.
