We evaluated the association of BGC use with thrombectomy outcomes and examined potential effect modification by occlusion location.</p>Methods<p>We retrospectively analyzed 475 patients with anterior-circulation large-vessel occlusion undergoing mechanical thrombectomy (BGC, n=242; non-BGC, n=233).

Procedural, angiographic, and clinical outcomes were compared between groups. Multivariable logistic regression models adjusted for age, sex, baseline NIHSS, collateral status, occlusion location, atrial fibrillation, hypertension, diabetes mellitus, and coronary artery disease. BGC × occlusion-location interactions were assessed using adjusted generalized linear models.</p>Results<p>BGC use was independently associated with higher odds of 90-day functional independence (mRS 0–2; adjusted OR [aOR], 1.61; 95% CI, 1.05–2.48; p=0.029) and lower odds of embolization to new territory (aOR, 0.53; 95% CI, 0.35–0.81; p=0.004).
