1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

BACKGROUND AND

objectivesThe Silk Vista Baby (SVB) flow diverter (FD) stent (Balt SAS) is the first device designed for treating distally located brain aneurysms. It can be delivered through a 0.017-inch ID microcatheter, enabling access to small, distal vessels. The aim of this study was to evaluate the effectiveness, safety, technical success, occlusion rate, and clinical outcomes of the SVB device.

methodsThis retrospective, multicenter study included data from 18 centers from November 2023 to September 2024. Procedures were performed by experienced neurointerventionalists following institutional standards of care. Outcomes analyzed included effectiveness, safety, and aneurysm occlusion rates. Descriptive analyses and Pearson χ 2 or Independent t -Test were used for statistical evaluation.

resultsA total of 95 patients, mean age 55.4 years, were included. A total of 31% of aneurysms were ruptured at admission. Most (58.3%) were located in the anterior circulation, and 45% had previous treatment, mainly coiling (69.4%). Complication rates were higher for ruptured aneurysms (24.1%) compared with unruptured ones (9.2%). Two deaths occurred, 1 (1.1%) related to the procedure. At discharge, 87% of patients had modified Rankin Scale ≤2. The latest follow-up showed overall complete/near-complete occlusion rates of 76.1%, with 81.14% for ruptured and 73.43% for unruptured aneurysms. Technical success was higher in unruptured cases (100% vs 93.1%).

conclusionOur case series demonstrated the efficacy of the SVB with a high rate of technical success. The occlusion rates for ruptured cases are comparable with those of other FDs. However, the rates are lower for unruptured cases. This discrepancy is likely due to the characteristics of the aneurysms, particularly in the presence of side branches in bifurcation lesions. The SVB safety profile is similar to other FDs in unruptured cases, while the ruptured group presented more complications.
