Proposed predictors of the need for retreatment after coil embolization of unruptured cerebral aneurysms with major or minor recanalization: Analysis of a single center’s experience

Various risk factors for recanalization after coil embolization have been reported, but the indications for retreatment of recanalized aneurysms have not been determined. The aim of this study was to identify risk factors indicating the need for retreating recanalization during long-term follow-up (approximately 1 year). A total of 172 unruptured saccular aneurysms in 155 patients treated by initial coil embolization between February 2012 and...
