Subarachnoid Hemorrhage, Subarachnoid Hemorrhage, Aneurysmal
Conditions
Brief summary
Rationale: Intrasaccular neck occlusion devices have been used for unruptured aneurysm without safety concerns and good occlusion rates. In the setting of a subarachnoid hemorrhage, they could improve the rate of complete occlusion without safety concerns. Aim: To explore the safety and efficacy of intrasaccular neck occlusion devices in patients with acute subarachnoid hemorrhage caused by a ruptured saccular aneurysm by a one arm prospective registry. Study outcome: The primary outcomes is the rate of complete occlusion (Raymond-Roy I) and rebleeding at one year follow-up. The primary safety outcome is rate of rebleeding during the admission.
Interventions
All patients included will be treated the same: after catheterizing the affected vessel and microcatheterizing the aneurysm with a microcatheter of 0.021'' or 0.027'', the intrasaccular device (Neqstent® or Contour®) will be positioned. Depending of the operator preference, the use of an intrasaccular device could be associated with coiling (mandatory in the case of Neqstent®). Treatment must be performed without previous double antiplatelet treatment (allowing antiplatelet after aneurysm exclusion). Before the treatment all patients should undergo a flat panel CT.
