Here we present clinical outcomes 1 year after treatment.

The international subarachnoid aneurysm trial ISAT: What percentage of surgically clipped aneurysms have residual necks? The risk of late rebleeding is low, but is more common after endovascular coiling than after neurosurgical clipping. Mayer S, Kreiter K. Treatment of intracranial aneurysms by embolization with coils. Neurosurgical clipping versus endovascular coiling of patients with ruptured intracranial aneurysms. The International Subarachnoid Aneurysm Trial ISAT was a large multicentre, prospective randomised clinical medical trialcomparing the safety and efficacy of endovascular coil treatment and surgical clipping for the treatment of brain aneurysms.

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

We undertook a randomised, multicentre trial to compare these treatments in patients who were suitable for either treatment because the relative safety and efficacy of these approaches had not been established.

Updated data from the ISAT group in March shows that the higher aneurysm rate of isay is also sneurysm 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.

ISAT was criticised on a number of factors, many related to the randomization of the patient population. Although the initial ISAT analysis appeared to favor endovascular coiling over microsurgical clipping, subsequent meta-analysis have questioned that conclusion, finding higher incidences of recurrence.
