Predictors of Clinical Improvement, Angiographic Recanalization, and Intracranial Hemorrhage After Intra-Arterial Thrombolysis for Acute Ischemic Stroke

Abstract

The intra-arterial route for thrombolysis allows for greater diagnostic precision and achievement of a higher concentration of the thrombolytic agent in the vicinity of the clot. Disadvantages of this therapy lie in the cost and delay. Severity of stroke and site of angiographic occlusion may be important predictors of successful treatment.
