Stent-Assisted Coiling Followed by Ticagrelor Monotherapy Instead of Dual Antiplatelet Therapy in Unruptured Intracranial Aneurysm

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.
