Eligibility

Inclusion criteria

Inclusion criteria: Clinical diagnosis of acute ischemic stroke who undergo cerebral imaging with CT angiogram of brain and neck vessels.

Exclusion criteria

Exclusion criteria: Intracranial hemorrhage on initial imaging. Poor-quality or incomplete angiographic studies precluding collateral assessment. Stroke mimics or non-vascular causes of neurological deficit example seizure, metabolic encephalopathy, migraine, hypoglycemia, space occupying lesions.

Design outcomes

Primary

MeasureTime frame
Assessment of the pattern of vascular occlusion and collateral circulation with volume of cerebral infarction, specifically correlating CTA-based collateral grade with baseline NIHSS.Timepoint: At baseline at the time of hospital admission and initial emergency neuroimaging, within 24 hours of stroke onset.

Secondary

MeasureTime frame
Early functional outcome using the modified Rankin ScaleTimepoint: At hospital discharge.;Evolution of clinical stroke severity using the National Institutes of Health Stroke ScaleTimepoint: At 24 hours post-admission;Cerebral infarction volume estimation via Alberta Stroke Program Early CT Score & identification of anomalous collateral patternsTimepoint: At baseline & at hospital admission
