Abstract Aneurysmal subarachnoid hemorrhage (SAH) is a worldwide health burden with high fatality and permanent disability rates. The estimated worldwide incidence of SAH is 9/100,000 persons/year. Ruptured cerebral aneurysms account for 75%-85% of non-traumatic SAH. The overall prognosis depends on the volume of the initial bleed, re-bleeding, and degree of delayed cerebral ischemia. The International Subarachnoid Aneurysm Trial (ISAT) reported a favorable neurological outcome with the endovascular coiling procedure (D’Souza, 2015). Wide-neck (when the neck is >4 mm, or when the dome/neck ratio <1.5-2) intracranial aneurysms were originally thought to be either untreatable or very challenging to treat by endovascular means because of the risk of coil protrusion into the parent vessel. The introduction of the balloon remodeling technique (BRT) and later stents specifically designed for intracranial use has progressively allowed these lesions to be endovascularly treated |
