Embolization of very small (<= 3 mm) unruptured intracranial aneurysms: A large single-center experience on treatment of unruptured versus ruptured cases

摘要

OBJECTIVE: In selected cases, embolization can be indicated for very small unruptured intracranial aneurysms. Previous studies reported high intraprocedural rupture rates. Recent improvements of endovascular devices and availability of small, soft platinum coils may lead to improved safety and efficacy profiles.
