Coils or clips in subarachnoid haemorrhage? J Neurol Neurosurg Psychiatry ; 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 aneuryxm 7 years. Quality of life after subarachnoid hemorrhage [letter]. It appears that although endovascular coiling is associated with a shorter recovery period as siat to surgical clipping, it is also associated with a significantly higher recurrence rate after treatment.


The risk of epilepsy was substantially lower in patients allocated to endovascular treatment, but the risk of late rebleeding was higher. More on ISAT [letter]. Published by Wolters Kluwer – Medknow.
