简要总结
This is a randomized, open label, multi-center, positive-controlled study, in which a total of 236 patients will be enrolled and randomly assigned to receive bivalirudin or heparin in a 1:1 ratio during coil embolization in patients with ruptured intracranial aneurysms.
Procedure-related complication, mRS, Activated Clotting Time, ischemic and hemorrhagic complications, symptomatic and asymptomatic intracranial hemorrhage, death, Heparin Induced Thrombocytopenia will be evaluated during procedure, at 24hs, 7days and 30 days after.
详细描述
Endovascular embolization has become an effective modality for the treatment of intracranial aneurysms. Despite advances in technology and techniques, thromboembolic and bleeding events are still encountered as inherent perioperative complications. Hypercoagulability as a systemic response to acute subarachnoid hemorrhage (SAH) may be associated with an increased incidence of thromboembolic events.
The administration of anticoagulant may reduce thromboembolic events during the endovascular embolization, meanwhile, involves the risk of bleeding. Although heparin is commonly used during the procedure, the safety in patients with ruptured intracranial aneurysms has not been established. In contrast to heparin, bivalirudin is a short-lived direct thrombin inhibitor with an intrinsic antiplatelet activity and more stable pharmacokinetic and pharmacodynamic properties which has been associated with reduced bleeding and an overall favorable profile. Bivalirudin administration in patients with high bleeding risk during coronary intervention is recommended by current guidelines.
This is an open label, multicenter, randomized pilot study, which is aimed to investigate the safety and efficacy of bivalirudin coil embolization in patients with ruptured intracranial aneurysms.
