Brief Summary

Un-ruptured intracranial aneurysm is a complex disease that seriously affects human life and health. At present, the treatment of intracranial aneurysm is divided into interventional treatment and craniotomy clipping, the two treatment methods are different in the intervention effect of aneurysm, for example, the complications of interventional therapy are lower than craniotomy clipping, but the long-term patency rate is lower than craniotomy clipping, and there is no standard of treatment in different parts of aneurysm in our country, the choice of intervention measures of un-ruptured aneurysm is different in different clinical centers; on the other hand, there are serious problems in the treatment of aneurysms, because without the relevant guidelines of diagnosis and treatment of intracranial aneurysms, different clinical centers will cause excessive treatment of un-ruptured aneurysms, not only bring unreasonable utilization of medical resources, but also cause the subject's life and property to be threatened. The patients with un-ruptured intracranial aneurysm(estimated sample number over 1500) were included in prospective cohort study, after clipping and intervention operation, setting fixed time for postoperative follow-up, the clinical data and image data were recorded, the safety, efficacy and economic benefits of interventional treatment and craniotomy clipping were compared, providing strategies for the standardized treatment of un-ruptured intracranial aneurysms.
