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. 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 aneurhsm aneurysms appears to be 8 times higher than that of clipping ieat aneurysms in this study.

Treatment of intracranial aneurysms by embolization with coils. Secondary outcomes included rebleeding from the treated aneurysm and risk of seizures. They reported finding outcomes similar to the ISAT. The risk of late rebleeding is low, but is more common after endovascular coiling than after neurosurgical clipping.

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.
