Editorial: Coils and rebleeding

Restricted access

With publication of the late results of the International Subarachnoid Aneurysm Trial (ISAT) study,2 and continued refinements of endovascular techniques, coil embolization is rapidly becoming the therapy of choice for the majority of patients with ruptured intracranial aneurysms in many neurovascular units worldwide. Despite the safety of the procedure and its undoubtedly less invasive nature when compared to surgical treatment, concerns remain about the durability of treatment. Moreover, in the ISAT study only a small proportion of the patients originally screened were eventually enrolled. This observation has generated questions whether the results of ISAT can indeed be generalized
