Rupture of an intracranial aneurysm is a diagnostic and therapeutic emergency. Occlusion of the aneurysm with coils is the first line treatment and should be performed promptly to avoid any further rupture, which carries a poor prognosis. Most aneurysms are accessible to this type of treatment. The risks of coiling, which are mostly thromboembolic and less commonly hemorrhagic due to peroperative rupture, are low. The use of stents or a flow diverter requires dual anti-aggregation which increases their risks so that their use are restricted to specific situations such as dissecting aneurysms. Endovascular treatment is effective in the long and short term prevention of recurrent hemorrhage provided that patients are followed up by imaging, which allows possible early recanalization to be detected early and treated if necessary.
