Thromboembolic events associated with balloon-assisted coil embolization: evaluation with diffusion-weighted MR imaging.

Abstract

The risk of thromboembolic events during the treatment of intracranial aneurysms with balloon-assisted techniques is not more significant than when conventional GDC techniques are used. The only variables found to influence this risk during or after balloon-assisted coil placement were microcatheter repositioning, coil removal and repositioning, and size of the aneurysmal neck.
