The Silk Vista Baby - The UK experience

Area of Science:

• Neurosurgery
• Interventional Neuroradiology
• Vascular Neurology

Background:

• The Silk Vista Baby (SVB) flow diverter is unique for its 0.017-inch microcatheter deliverability.
• It is specifically designed for treating aneurysms in the distal vasculature.

Purpose of the Study:

• To evaluate the safety and efficacy of the SVB flow diverter.
• Assess its performance in treating distal cerebral aneurysms.

Main Methods:

• Retrospective review of SVB cases across 4 UK neurosurgical centers.
• Collection of clinical, procedural, angiographic, and follow-up data.

Main Results:

• 60 patients with 61 aneurysms treated; 81.9% in the anterior circulation.
• Successful implantation with an average of 1.07 devices per aneurysm.
• At 7.5 months follow-up, 57.1% achieved complete occlusion (RRC I).
• 4.1% experienced clinical complications; 5.1% mortality rate, with 3.4% aneurysm-related deaths.
• 93% of patients had modified Rankin Scale (mRS) ≤ 2 at last follow-up.

Conclusions:

• The SVB flow diverter demonstrates high technical success rates.
• It possesses an acceptable safety profile for treating distal aneurysms.
• Slower occlusion rates may occur in distal aneurysms, potentially due to device oversizing.
