RESUMO
BACKGROUND: Surpass Evolve Flow Diverter (SE-FD; Stryker Neurovascular, Kalamazoo, MI, USA) was launched in 2019 as a new generation FD of Surpass Streamline. The aim of this study was to report the effectiveness and safety of SE-FD insertion for unruptured intracranial aneurysm at one-year follow-up. METHODS: Between November 2019 and October 2021, a total of 106 patients with 108 aneurysms were treated with FD in single institution. Of these, SE-FD insertion was performed in 40 patients with 41 aneurysms. At one-year follow-up, clinical and angiographic outcomes were retrospectively evaluated from electronic medical record and aneurysm database. RESULTS: There were 12 male and 28 female patients (mean age 59.1 years, 95% CI: 55.3-62.9). Fusiform aneurysm dissection was 46.3% (19/41). Mean maximum aneurysm diameter was 13.2 mm (SD 5.53), and 34.1% (14/41) of aneurysms were 15 mm or bigger. Among 41 aneurysms, complex aneurysm (recurred, thrombosed, or branch artery-incorporated) was accounted for 41.5% (17/41). All procedures were successfully conducted with 7.3% (3/41) of procedure-related complications. At one-year follow-up (N.=40), neurologic morbidity was noted in 2 cases (5.0%; both with modified Rankin Scale [mRS] 1) without any mortality. At one-year follow-up (N.=41), radiologic outcomes were adequate occlusion in 33 (80.5%) and complete occlusion in 29 (70.7%). There was no retreatment in our cohort. CONCLUSIONS: Surpass Evolve Flow Diverter seemed to be safe and effective for the treatment of dissecting/fusiform or complex aneurysms at one-year follow-up. However, further study is needed to evaluate long term results.
RESUMO
AIM: Memantine is known to be effective in the treatment of the behavioral symptoms of dementia, especially agitation in moderate to severe Alzheimer's disease (AD). However, memantine and rivastigmine patch combination therapy has not been well studied in determining treatment effectiveness with mild to moderate AD patients. METHODS: This was a multicenter, 24-week, prospective, randomized, open-label study design. A total 147 AD patients with Mini-Mental State Examination scores from 10 to 20 were randomly assigned to rivastigmine patch monotherapy and combination therapy with memantine groups. Agitation symptoms, using the Korean Version of the Cohen Mansfield Agitation Inventory were evaluated at baseline and at study end. Suppression and emergence of agitation symptoms were also evaluated. We carried out factor analyses to evaluate the interrelationship of agitation symptoms and to investigate treatment response in these symptoms. RESULTS: Factor analyses showed two symptom clusters: factor A - aggressive agitated behaviors - versus factor B - non-aggressive agitated behaviors. The rivastigmine patch monotherapy group showed significantly decreased factor B scores and had a tendency of decreased Korean Version of the Cohen Mansfield Agitation Inventory total scores and factor A scores. Conversely, the combination therapy group showed significantly increased Korean Version of the Cohen Mansfield Agitation Inventory total scores and factor B scores. Neither monotherapy nor combination therapy reduced the emergence of new agitation symptoms. CONCLUSIONS: In this trial of mild to moderate AD patients, the rivastigmine patch monotherapy group experienced a reduction of non-aggressive agitated behaviors. However, combination therapy with memantine did not show any benefit on the agitation associated with mild to moderate AD. Geriatr Gerontol Int 2017; 17: 494-499.
