Symptomatic Intracranial Atherosclerosis in an Australian Context: Common and Underdiagnosed in Multiple Ethnic Groups.

ABSTRACT:

Background

Intracranial atherosclerosis (ICAD) is a common cause of stroke globally. We calculated the proportion of patients with stroke with symptomatic intracranial atherosclerosis in an Australian multiethnic setting, as well as diagnostic rates by stroke physicians and radiologists.

Methods

This was a multicenter retrospective cohort study based in Melbourne, Australia. Demographic data (including self-reported ethnicity) and data on vascular risk factors were collected. Symptomatic ICAD was independently identified by 2 blinded stroke neurologists using multiplanar reformats and maximum intensity projections of routinely acquired thin slice computed tomography angiography data, with disagreements resolved by a third blinded stroke neurologist.
