Endovascular coiling of intracranial aneurysms has been shown to be safe and efficacious in the treatment of intracranial aneurysms. The International Subarachnoid Aneurysm Trial (ISAT) has shown that endovascular coiling can reduce morbidity and mortality compared to clipping of aneurysms in the setting of SAH. [8]. The goal of endovascular coiling is to prevent rupture or rebleeding by isolating an aneurysm from the normal blood circulation without narrowing the parent vessel.
