Leptomeningeal Collaterals and Infarct Progression in Patients With Acute Large-Vessel Occlusion and Low NIHSS.

ABSTRACT:

Background

Approximately 10% of patients with acute ischemic stroke with large-vessel occlusion (LVO) have mild neurological deficits. Although leptomeningeal collaterals (LMCs) are the major determinant of clinical outcomes for patients with acute ischemic stroke with LVO, the contribution of baseline LMC status to subsequent infarct progression in patients with mild stroke with LVO is poorly defined.

Methods

This observational study included patients with acute anterior circulation LVO and mild stroke symptoms (National Institutes of Health Stroke Scale < 6) from a prospectively collected, multicenter, national stroke registry. The Alberta Stroke Program Early Computed Tomography Score was quantified on the initial and follow-up images. An infarct progression, defined as a
