Abstract

Background: Previous trials confirmed the benefit of endovascular treatment (EVT) in acute large core stroke, but the effect of EVT on outcomes in these patients based on non-contrast computed tomography (NCCT) in real-world clinical practice was unclear. The aim of this study was to explore the effect of EVT versus standard medical treatment (SMT) in patients with large ischemic core stroke defined as Alberta Stroke Program Early CT Score (ASPECTS)≤5 based on NCCT alone.

Materials and Methods: Patients with acute large core stroke at 38 Chinese centers between November 2021 and February 2023 were reviewed from prospectively maintained databases. The primary outcome was favorable functional outcome (modified Rankin Scale score [mRS], 0–3) at 90 days. Safety outcomes included 48-hour symptomatic intracerebral hemorrhage (sICH) and 90-day mortality.

Results: Of 745 eligible patients recruited at 38 stroke centers between November 2021 and February 2023, 490 were treated with EVT and 255 with SMT alone. One hundred and eighty-one (36.9%) in the EVT group achieved favorable functional independence versus 48 (18.8%) treated with SMT only (adjusted risk ratio [RR], 1.86; 95% CI, 1.43 to 2.42, P<0.001; adjusted risk difference [RD], 13.77; 95% CI, 7.40 to 20.15, P<0.001). The proportion of sICH was significantly higher in patients undergoing EVT (13.3% vs. 2.4%; adjusted RR, 5.17; 95% CI, 2.17 to 12.32, P<0.001; adjusted RD, 10.10; 95% CI, 6.12 to 14.09, P<0.001). No significant difference of mortality between the groups was observed (41.8% vs. 49.0%; adjusted RR, 0.91; 95% CI, 0.77 to 1.07, P=0.24; adjusted RD, -5.91; 95% CI, -12.91 to 1.09, P=0.1).

Conclusion: Among patients with acute large core stroke based on NCCT in real world, EVT is associated with better functional outcomes at 90 days despite of higher risk of sICH. Rates of procedure-related complications were high in the EVT group.
