  • Description: Background and Purpose: Low-profile flow diverter stents (FDS) quite recentlyamended peripheral segments as targets for hemodynamic aneurysm treatment;however, reports on outcomes, especially later than 3 months, are scarce. This studytherefore reports our experience with the novel silk vista baby (SVB) FDS and respectiveoutcomes after 8 and 11 months with special respect to specific adverse events.Materials and Methods: Forty-four patients (mean age, 53 years) harboring 47aneurysms treated with the SVB between June 2018 and December 2019 were includedin our study. Clinical, procedural, and angiographic data were collected. Follow-ups wereperformed on average after 3, 8, and 11 months, respectively. Treatment effect wasassessed using the O’Kelly Marotta (OKM) grading system.Results: Overall, angiographic follow-ups were available for 41 patients/45 aneurysms.Occlusion or significant reduction in aneurysmal perfusion (OKM: D1, B1–B3 andA2–A3) was observed in 98% of all aneurysms after 8 months. Only 2% of the treatedaneurysms remained morphologically unaltered and without an apparent change inperfusion (OKM A1). Adverse events in the early post-interventional course occurredin seven patients; out of them, mRS-relevant morbidity at 90 days related to FDStreatment was observable in two patients. One death occurred in the context ofsevere SAH related to an acutely ruptured dissecting aneurysm of the vertebral artery.Conclusion: The SVB achieves sufficient occlusion rates of intracranial aneurysmsoriginating from peripheral segments, which are comparable to prior establishedconventional FDS with acceptably low complication rates. However, alteration of ahemodynamic equilibrium in distal localizations requires special attention to preventischemic events.
