From Wikipedia, the free encyclopedia. The impact of the international subarachnoid aneurysm trial ISAT on neurosurgical practice. International subarachnoid aneurysm trial ISAT of neurosurgical clipping versus endovascular coiling in patients with ruptured intracranial aneurysms: Could late ansurysm overturn the superiority of cranial aneurysm coil embolization over clip ligation seen in ISAT? More on ISAT [letter].

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. A critical review of the literature.


The risk of epilepsy was substantially lower in patients allocated to endovascular treatment, but the risk of late rebleeding was higher. Here we present clinical outcomes 1 year after treatment. Journal of Neurosurgery 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 aneurydm had not been established.

Long-term angiographic recurrences after selective endovascular treatment of aneurysms with detachable coils. 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.


They reported finding outcomes similar to the ISAT. What percentage of surgically clipped aneurysms have residual aneurydm

It appears that although endovascular coiling is associated with a shorter recovery period as compared to surgical clipping, it is also associated with a significantly higher recurrence rate after treatment.
