Clinical Trial Summary

The primary goal of the trial is to investigate whether the experimental arms (receiving the P2Y12 inhibitor Ticagrelor) compared with the control arm (taking dual antiplatelet therapy) could reduce bleeding complications in patients with intracranial aneurysms undergoing Stent-Assisted Coiling.

Clinical Trial Description

Bleeding complications associated with the use of DAPT have been of great concern, with up to one-third of PCI patients treated with DAPT previously reported to suffer from nuisance bleeding. Once any of these bleeding complications occur, adherence to the DAPT regimen may become difficult. Antiplatelet agents are necessary for patients undergoing stent-assisted spring coil embolisation of intracranial aneurysms and are key to reducing thrombosis leading to ischaemic stroke events in post-procedural patients. Currently neither long-term DAPT nor short-duration DAPT followed by aspirin monotherapy is fully satisfactory. Patients with aneurysms without underlying intracranial atherosclerotic disease have relatively lower ischaemic risk factors, and antiplatelet medication after stenting remains to be improved. Ticagrelor monotherapy was associated with a lower risk of major bleeding and no measurable increase in ischaemic events after a short course of 1- or 3-month DAPT. The study indicated no difference in stroke or death between mono- and dual-antiplatelet therapy after carotid artery placement, and P2Y12 inhibitor monotherapy may be an effective strategy to reduce severe bleeding complications while preserving ischemic benefits for patients. This study investigates the comparative efficacy and safety of stent-assisted coiling therapy for intracranial aneurysms after ticagrelor monotherapy as an alternative to dual antiplatelet therapy, to reduce the incidence of bleeding complications in patients, and thus to improve the antiplatelet strategy after stent-assisted coiling therapy for intracranial aneurysms. ;
