Key Points

To evaluate the relationship between venous outflow and outcomes in patients with acute ischemic stroke caused by large vessel occlusion treated with endovascular thrombectomy.
Analyzed patients with acute ischemic stroke from large vessel occlusion
Focused on those treated with multiple endovascular thrombectomy passes (≥3)
Measured NIHSS scores and successful reperfusion rates.
Lower NIHSS scores at presentation correlated with favorable outcomes
Successful reperfusion was associated with improved outcomes
Good venous outflow was linked to a higher likelihood of favorable results.

Implication

Observational analysis shows association of venous outflow with outcomes in acute ischemic stroke patients, suggesting potential therapeutic focus.

Abstract

In Patients with AIS-LVO treated with EVT that involved ≥3 passes, lower presentation NIHSS, successful reperfusion, and favorable VO were associated with an increased likelihood of a favorable outcome.
