The overall complete occlusion rate at 3months was higher in the WEB17 group (65.5% versus 55.1%). The superiority of complete aneurysm occlusion achieved with WEB17 was statistically significant in the subgroup of unruptured middle cerebral artery aneurysms. The use of WEB17 expands the treatment indications for intrasaccular flow-diversion towards smaller and more distally located aneurysms with asafety profile comparable with that of the WEB21. The use of WEB 17 expands the treatment indications for intrasaccular flow-diversion towards smaller and more distally located aneurysms with a safety profile comparable with that of the WEB 21. Adenotonsillectomy (AT) is associated with improved behavior in children with obstructive sleep apnea (OSA). However, it is unknown whether polysomnographic parameters are superior to the parent-reported severity of sleep-disordered breathing (SDB) in predicting behavioral changes after AT. To ascertain whether polysomnographic parameters vs parent-reported severity of SDB are better predictors of treatment-related behavioral changes in children with OSA. This ad hoc secondary analysis of the Childhood Adenotonsillectomy Trial (CHAT) downloaded and analyzed data from January 1 to January 31, 2020. Children aged 5 to 9 years with a polysomnographic diagnosis of OSA were enrolled in the CHAT and subsequently randomized to undergo either early AT or watchful waiting with supportive care. All outcome measures were obtained at baseline and at follow-up (7 months after randomization). Early AT vs watchful waiting with supportive care. Postrandomization changes between the baseline and follow-up periods weperiods were partially mediated by the changes in PSQ-SRBD scores (range of nonzero causally mediated effects, 2.4-3.5), without contribution from any of the polysomnographic parameters.
