      Predictors of Cerebral Aneurysm Rupture after Coil Embolization: Single-Center Experience with Recanalized Aneurysms

      The authors evaluated a total of 426 unruptured aneurysms and 169 ruptured aneurysms that underwent coil embolization in their institution between January 2009 and December 2017. Recanalization occurred in 38 (8.9%) of 426 unruptured aneurysms and 37 (21.9%) of 169 ruptured aneurysms. The Modified Raymond-Roy Classification on DSA was used to categorize the recanalization type. In untreated recanalized aneurysms, class IIIb aneurysms ruptured significantly more frequently than class II and IIIa. In the ruptured group, the median follow-up term was 28.0 months. Retreatment for recanalization was performed in 16 aneurysms. Four of 21 untreated recanalized aneurysms (2.37% of total coiled aneurysms) ruptured. Class IIIb aneurysms ruptured significantly more frequently than class II and IIIa. Coiled aneurysms with class IIIb recanalization should undergo early retreatment because of an increased rupture risk.

The Modified Raymond-Roy Classification on DSA was used to categorize the recanalization type. In untreated recanalized aneurysms, class IIIb aneurysms ruptured significantly more frequently than class II and IIIa. In the ruptured group, the median follow-up term was 28.0 months. Retreatment for recanalization was performed in 16 aneurysms. Four of 21 untreated recanalized aneurysms (2.37% of total coiled aneurysms) ruptured. Class IIIb aneurysms ruptured significantly more frequently than class II and IIIa. Coiled aneurysms with class IIIb recanalization should undergo early retreatment because of an increased rupture risk.

      Focal signal abnormalities at the depth of the cerebellar fissures in children have been reported and hypothesized to represent a novel pattern of bottom-of-fissure dysplasia. The authors report a series of 23 patients with a similar distribution and appearance of cerebellar signal abnormality attributable to watershed injury. T2 prolongation was observed at the depths of the cerebellar fissures bilaterally in all 23 patients, centered at the expected location of the deep cerebellar vascular borderzone. Diffusion restriction was associated with MR imaging performed during acute injury in 13/16 patients. Five of 23 patients had prior imaging, all demonstrating a normal cerebellum. The etiology of injury was hypoxic-ischemic injury in 17/23 patients, posterior reversible encephalopathy syndrome in 3/23 patients, and indeterminate in 3/23 patients.
