Abstract

fetched live from OpenAlex

Background: Basilar artery stenting is a rescue therapy in the management of hyperacute stroke Published data on efficacy and safety are limited. Methods: A systematic review of published studies was performed in accordance with PRISMA guidelines. Inclusion criteria were adult patients with ischemic stroke with permanent basilar artery stent placement within 48 hours of onset. Data were extracted by two independent reviewers. Additional cases from our institution were identified via a local stroke registry. Results: Of 212 screened articles, patient-level data was reported in 35 studies (93 individuals) and six additional patients were included from our registry. Patients (n=99, 63% male; median age 64) most often presented with mid-basilar occlusion (52%) and 76% received treatment within 12 hours of onset. Favorable angiographic results occurred in 67%. The final modified Rankin Scale score (mRS) was 0-3 for 56% of patients; mortality was 29%. Those with complete flow post-procedure were more likely to have a final mRS of 0-3 (p=0.05). Conclusions: In 99 cases of basilar stenting in hyperacute stroke, favourable angiographic and functional outcomes were reported in 67% and 56% of patients, respectively. International multicenter registries are required to establish benefit and identify patient and technical factors that predict favorable outcomes.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
