Abstract
Background
The Silk Vista Baby (SVB) flow diverter (FD) is a stent designed for small vessels ranging from 1.5 to 3.5 mm. It is the only FD deliverable through a 0.017-inch microcatheter. This systematic review and meta-analysis aimed to assess the SVB utilization in intracranial aneurysms (IAs).
Methods
Four electronic databases, PubMed, Scopus, Embase, and Web of Science, were searched from inception to November 5th, 2024.
Results
Ten studies with 359 patients with 373 IAs were included. Our results revealed a pooled complete occlusion rate of 65% (95%CI: 43%–83%), a favorable outcome rate of 94% (95%CI: 83%–100%), and a morbidity rate of 4% (95%CI: 0%–11%). Our meta-analysis revealed a pooled in-stent thrombosis rate of 2% (95%CI: 1%–5%), side branch occlusion rate of 2% (95%CI: 0%–3%), intracerebral hemorrhage (ICH) rate of 2% (95%CI: 1%–4%), and device shortening rate of 4% (95%CI: 3%–6%). The subgroup analysis showed that the complete occlusion rate (≤6: 84% [95%CI: 49%–100%] vs >6: 58% [95%CI: 41%–73%],
Conclusion
SVB is an efficient and safe therapeutic option for managing IAs. We demonstrated that it is associated with promising clinical and radiological outcomes and low rates of complications.
