Relevance of peripheral inflammation indexes in different collateral circulation for intracranial hemorrhage in acute anterior circulation ischemic stroke patients undergoing endovascular treatment

Asymptomatic intracranial hemorrhage (aICH) is common after endovascular thrombectomy (EVT). Collateral circulation could modify the association between aICH with functional outcome and we aimed to investigate the impact of systemic inflammation index on 3-month outcome under different collateral circulation.
