Implication

This analysis reveals that thrombectomy use declines significantly as time from stroke onset increases, highlighting key treatment timing implications.

Key Points

To characterize changes in thrombectomy utilization within the 24-hour window after acute stroke due to large vessel occlusion.
Analyzed data from the Get With The Guidelines-Stroke registry.
Identified patients with proximal large vessel occlusion and NIHSS ≥ 6.
Stratified patients by time from last known normal to vascular imaging.
Modeled odds of thrombectomy using generalized estimating equations accounting for demographics and hospital factors.
12.8% of patients within 0–5.5 hours underwent thrombectomy, compared to lower rates in later time windows.
Odds of thrombectomy decreased by 32.8% at 5.5–11.5 hours, 46.0% at 11.5–17.5 hours, and 66.8% at 17.5–23.5 hours.
Each additional hour of delay corresponded to a 6.0% reduction in the odds of receiving thrombectomy.
