Background and Purpose: Low-profile flow diverter stents (FDS) quite recently
amended peripheral segments as targets for hemodynamic aneurysm treatment;
however, reports on outcomes, especially later than 3 months, are scarce. This study
therefore reports our experience with the novel silk vista baby (SVB) FDS and respective
outcomes after 8 and 11 months with special respect to specific adverse events.
Materials and Methods: Forty-four patients (mean age, 53 years) harboring 47
aneurysms treated with the SVB between June 2018 and December 2019 were included
in our study. Clinical, procedural, and angiographic data were collected. Follow-ups were
performed on average after 3, 8, and 11 months, respectively. Treatment effect was
assessed 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 and
A2–A3) was observed in 98% of all aneurysms after 8 months. Only 2% of the treated
aneurysms remained morphologically unaltered and without an apparent change in
perfusion (OKM A1). Adverse events in the early post-interventional course occurred
in seven patients; out of them, mRS-relevant morbidity at 90 days related to FDS
treatment was observable in two patients. One death occurred in the context of
severe SAH related to an acutely ruptured dissecting aneurysm of the vertebral artery.
Conclusion: The SVB achieves sufficient occlusion rates of intracranial aneurysms
originating from peripheral segments, which are comparable to prior established
conventional FDS with acceptably low complication rates. However, alteration of a
hemodynamic equilibrium in distal localizations requires special attention to prevent
ischemic events.
