Prevalence and long-term clinical significance of intracranial atherosclerosis after ischaemic stroke or transient ischaemic attack: a cohort study.

ABSTRACT:

Objectives

We investigated the prevalence and long-term risk associated with intracranial atherosclerosis identified during routine evaluation.

Design

This study presents data from a prospective cohort of patients admitted to our stroke unit for thrombolysis evaluation.

Setting and participants

We included 652 with a final diagnosis of ischaemic stroke or transient ischaemic attack (TIA) from April 2009 to December 2011. All patients were acutely evaluated with cerebral CT and CT angiography (CTA). Acute radiological examinations were screened for intracranial arterial stenosis (IAS) or intracranial arterial calcifications (IAC). Intracranial stenosis was grouped into 30-50%, 50-70% and >70% lumen reduction. The extent of IAC was graded as number of vessels affected.<
