Factors Affecting the Prognosis of Patients with Acute Cerebrovascular Occlusion with High National Institutes of Health Stroke Scale Scores Treated with SWIM Technology.
Bibliographic record
Abstract
Objective: We aimed to explore the factors affecting the prognosis of patients with acute cerebrovascular occlusion with high National Institutes of Health Stroke Scale (NIHSS) scores treated with the SWIM (Solitaire™ stent retriever-assisted thrombectomy with immediate mechanical aspiration) technique using an intracranial support catheter. Methods: A retrospective analysis was conducted in 72 patients with acute cerebrovascular occlusion who underwent SWIM surgery in the Affiliated Hospital of Chengde Medical University in China between January 2020 and June 2022. The patients were divided into a good prognosis group (Modified Rankin Score [mRS] 0 to 2; n = 30) and a poor prognosis group (mRS score 3 to 6; n = 42) on their mRS scores 3 months after surgery. The THRIVE (TICI, hemorrhage, reocclusion, infarction, vessel, and embolism) score at different time points before and after the SWIM procedure and the postoperative revascularization rate were compared in the 2 NIHSS score groups. Univariate and logistic regression analyses were performed to identify the risk factors that affected the prognosis of patients with acute cerebrovascular occlusion treated with the SWIM procedure. Results: The NIHSS score difference at various time points after SWIM surgery in patients with low to moderate NIHSS scores was significantly higher than in patients with high NIHSS scores (P < .05). The postoperative revascularization rate in patients with high NIHSS scores was 74.36%, which was not significantly different from that in patients with low to moderate scores (84.85%; P > .05). The poor prognosis in patients with acute cerebrovascular occlusion after SWIM surgery was related to age, hypertension, NIHSS score, Glasgow Coma Scale (GCS) score, Essen Stroke Risk Score (ESRS), onset-to-treatment time (OTT) and Alberta Collateral Grading Scale (ACGS) score (P < .05). Logistic regression analysis showed that age, admission NIHSS score and ACGS score were independent risk factors that affected the prognosis in patients with acute cerebrovascular occlusion treated with the SWIM procedure (P < .05). Conclusion: The prognosis in patients with acute cerebrovascular occlusion with high NIHSS scores after SWIM surgery was poor. Advanced age, high NIHSS score and ACGS score were independent risk factors that affected the prognosis in patients with acute cerebrovascular occlusion treated with the SWIM procedure. Overall, incorporating these findings into clinical practice promotes personalized approaches, interdisciplinary collaboration and timely interventions to optimize outcomes in patients undergoing the SWIM procedure for acute cerebrovascular occlusion.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
