Consecutive coil migrations through solitaire ab stent during stent assisted coiling of an aneurysm: a case report

Abstract

Endovascular treatment has been established as a safe and efficacious approach to the treatment of cerebral aneurysms. These stents provide support to decrease the risk of coil herniation. However, complications associated with stent-assisted embolization include aneurysm recurrence, stent migration, in-stent stenosis, and hemorrhagic and thromboembolic complications. Herein, we report a case of consecutive coil migrations into the distal middle cerebral artery (MCA) during stent-assisted coil embolization. F/U 1-month perfusion magnetic resonance imaging showed no hypoperfusion in the MCA territory.
