Distinct intra‐arterial clot localization affects tissue‐level collaterals and venous outflow profiles

Arterial clot localization affects collateral flow to ischemic brain in patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO). We determined the association between vessel occlusion locations, tissue-level collaterals (TLC), and venous outflow (VO) profiles and their impact on good functional outcomes.We conducted a multicenter retrospective cohort study of consecutive AIS-LVO patients who underwent thrombectomy triage....
