UNASSIGNED: OBJECT The incidence and risk factors of @entity75 on MR diffusion-weighted imaging (DWI) were analyzed after the endovascular coiling of @entity438 ( @entity438 ). METHODS Data obtained from 271 consecutive @entity1 (70 @entity1 and 201 @entity1 ; median age 57 years; range 23-79 years) who presented with UIA for coil embolization between July 2011 and June 2013 were analyzed. Two independent reviewers examined the DWI and apparent diffusion coefficient maps obtained the following day for the presence of restrictive diffusion spots and counted the number of spots. Multivariate analysis was then performed to identify independent risk factors for developing microembolism following the coiling of an @entity439 . RESULTS @entity75 were noted in 101 of 271 @entity1 (37.3%). The results of the multivariate analysis showed that the following factors significantly influenced the risk for microembolism: age, @entity6 , previous history of @entity385 , high-signal FLAIR lesions in the white matter, @entity439 , and the insertion of an Enterprise stent (all ORs > 1.0 and all p values < 0.05). Previously known risk factors such as prolonged procedure duration, @entity439 size, and decreased antiplatelet function did not show any significant influence. CONCLUSIONS The incidence of microembolism after endovascular coiling of UIA was not low. Lesions occurred more frequently in @entity1 with vascular status associated with old age, @entity6 , and previous @entity64 . @entity439 multiplicity and the type of stent used for treatment also influenced lesion occurrence.
