Intracranial Vessel Ratio Measured by DSA Is a Predictive Factor for Recanalization in Acute Ischemic Stroke

Background and Purpose. This study aims to describe the relationship between intracranial vessel ratios (ie, the relative size of the parent vessel over its direct branches) and immediate recanalization after intra-arterial (IA) thrombolysis, with and without intravenous (IV) thrombolysis.
