In-stent thrombosis and stenosis after neck-remodeling device-assisted coil embolization of intracranial aneurysms.

Background: Intrinsic thrombosis and stenosis are complications associated with the use of neck-remodeling devices in the treatment of intracranial aneurysms.

Objective: To examine the technical and anatomic factors that predict short- and long-term stent patency.

Methods: We undertook a retrospective review of 161 patients who underwent coil embolization of 168 ruptured and unruptured aneurysms assisted by the use of a neck-remodeling device.
