Delayed Ischemic Stroke after Stent-assisted Coil Placement in Cerebral Aneurysm: Characteristics and Optimal Duration of Preventative Dual Antiplatelet Therapy

Delayed ischemic stroke after stent-assisted coil repair of cerebral aneurysm is caused by embolism from the stent or thrombotic occlusion of the stent-containing vessel after early switch of dual antiplatelet therapy to monotherapy, and thus longer-term dual antiplatelet therapy for more than 9 months and late switch to monotherapy are necessary to prevent delayed ischemic stroke.
