DERIVO 2 Embolization Device (DED2) is a new addition to the market and promises better radiopacity. 1 Aim of study The purpose of this study was to evaluate the safety and efficacy of the DED2. Methods We conducted a retrospective multicenter analysis at six interventional facilities. Patients with unruptured or ruptured intracranial aneurysms were included. The primary objective was angiographic aneurysm occlusion at 6 months as measured by the OKM grading scale. Clinical outcome according to mRS was evaluated at 6 months, with major morbidity defined as mRS 3-5. Results We included 37 patients treated with the DED2 between August 2020 and July 2021. Five patients had ruptured aneurysms. 27 patients were female, 10 male, with a medium age of 60. The median mRS was 0 (range 0-4). Average aneurysm size was 9.1 (7.9) mm, while average neck size was 6.8 (6.3) mm. In all cases the DED2 opened upon deployment. Thirty patients were eligible for clinical follow-up (81.1%). 25 (83.3%) had an mRS of 0 or 1, with no clinical deterioration in patients with pre-existing significant morbidity. Three patients died during the follow-up period, two of whom had ruptured aneurysms initially. Follow-up imaging was available in 27 patients (90%), with 23 (85.2%) demonstrating satisfactory aneurysm occlusion OKM grade C-D. Conclusion The DED2 is both safe and effective in the treatment of ruptured and unruptured intracranial aneurysms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
