Role of CT Angiography in Patient Selection for Thrombolytic Therapy in Acute Hemispheric Stroke

Abstract

CTA can provide important information for the initiation of therapy in patients with acute hemispheric ischemia. Identification of patients with autolyzed thrombi, occlusion of the internal carotid artery bifurcation, and poor leptomeningeal collaterals is feasible with the use of CTA. These patients may have little potential for benefit from thrombolytic therapy.
