INTRODUCTION: Delayed @entity1756 and delayed @entity548 (DIPH) are poorly understood and often fatal complications of @entity450 ( @entity450 ) for @entity438 . The purpose of this study was to identify risk factors for these complications. METHODS: We performed a systematic review on post- @entity450 delayed @entity1756 and DIPH. For each reported case, we collected the following information: @entity439 location, size and @entity397 status, type of flow diverter used, timing of the @entity548 , and neurological outcome. We reported descriptive statistics of @entity1 suffering DIPH and delayed @entity1756 to determine if there were any characteristics consistently present among @entity1 with these complications. RESULTS: We identified 81 delayed @entity1756 and 101 DIPH. Of the delayed @entity397 , 76.6  % (45/58) occurred within 1  month. The prognosis of delayed @entity397 was poor, with 81.3  % (61/75) experiencing @entity204 or poor neurological outcome. @entity439 accounted for 46.3  % of @entity397 (31/67). Of these @entity439 , 80.9  % (55/68) were initially unruptured. Of the delayed @entity1756 , 17.8  % (13/73) had prior or concomitant coiling. DIPHs were ipsilateral to the treated @entity439 in 82.2  % (60/73) of cases. Of the DIPH, 86.0  % (43/50) occurred within 1  month after FDS. Combined morbidity/mortality rate was 68.5  % (50/73) following DIPH. Of DIPHs, 23.0  % (14/61) occurred in @entity1 with @entity439 . CONCLUSIONS: Our study demonstrates that @entity439 represent almost 50  % of delayed @entity1756 in the flow diverter literature. About 20  % of delayed @entity397 occurred despite associated coiling. A substantial proportion of DIPHs occur early following FDS treatment of @entity439 .
