International Subarachnoid Aneurysm Trial – Wikipedia

How to cite this URL: From Wikipedia, the free encyclopedia. Updated data from the ISAT group in March shows that the higher aneurysm rate of recurrence is also associated with a higher rebleeding rate, given that the rebleed rate of coiled aneurysms appears to be 8 times higher than that of clipping treated aneurysms in this study.

In patients with ruptured intracranial aneurysms suitable for both treatments, anneurysm coiling is more likely to result in independent survival at 1 year than neurosurgical clipping; the survival benefit continues for at least 7 years.
