Abstract
Despite the extensive work to explore the predictors and risk factors of rupture for unruptured aneurysms, many of the proposed factors are unfortunately unmodifiable e.g. gender, age, population,…etc. while many others are controversial. Female gender and age over 50, seem to harbor a higher risk not only for CA development, but also for their rupture.
Some aneurysm-related factors that would predict aneurysm rupture include; anatomical location, aneurysm size and aneurysm aspect ratio. Moreover, satisfactory aneurysm occlusion via coil embolization for unruptured CA, has been shown to effectively secure the aneurysm sac for at least one year after the initial coiling. However, ruptured status and initial incomplete aneurysm occlusion would predict recurrence and the need to retreat.
Moreover, during the acute phase after aneurysmal rupture, while securing the aneurysm comes as the most important step to protect against the detrimental rebleeding events, endovascular coiling despite the possible chances for recanalization, has been shown to be reliable and efficient to commence in such situation.
Periprocedural complications were reported with coil embolization, yet low incidence of such events along with the reported high rates of favorable outcome, would make endovascular coil embolization of cerebral aneurysm, a safe and effective modality of treatment.
Endovascular coiling has shown to provide an adequate and successful therapeutic tool to manage cerebral aneurysm and should be considered as an upfront option to treat such lesions.
