BACKGROUND: Stent-assisted coil embolization (SACE) is used to address wide-necked or complex @entity439 . However, as they may recanalize after SACE, predictors of recanalization are needed. We investigated the relationship between follow-up angiographic results and the morphology of sidewall (SW) @entity439 in @entity1 treated by SACE. METHODS: Between September 2010 and September 2014, we performed 80 SACE procedures for SW @entity438 . Angiographic findings, obtained immediately after the procedure, 3-6 months thereafter, and when aneurysmal recanalization was suspected on MR angiogram scan, were recorded. Morphologically, the SW @entity439 were classified as "outside" (OS) and "partially inside" (PI) based on the curve of the axes of the proximal or distal parent artery with respect to the @entity439 . Follow-up angiographic studies on OS- and PI SW @entity439 were compared. RESULTS: On the initial angiograms, we classified 42 @entity439 as OS and 38 as PI. Immediately after SACE, there was no significant difference in the angiographic findings on OS and PI @entity439 . However, on follow-up angiograms, there was a significant difference in the rate of spontaneous improvement (4 of 42 [OS] versus 21 of 38 [PI], P   =   .001). We performed additional coil embolization to treat 3 recanalized @entity439 . CONCLUSIONS: SW @entity439 classified morphologically as PI tended to occlude progressively even after incomplete occlusion by SACE. In contrast, @entity439 classified as OS must be observed carefully after SACE.
