The pattern of leptomeningeal collaterals on CT angiography is a strong predictor of long-term functional outcome in stroke patients with large vessel intracranial occlusion.

Abstract

BACKGROUND AND PURPOSE The role of noninvasive methods in the evaluation of collateral circulation has yet to be defined. We hypothesized that a favorable pattern of leptomeningeal collaterals, as identified by CT angiography, correlates with improved outcomes. METHODS Data from a prospective cohort study at 2 university-based hospitals where CT… (More)
