Hiding in Plain Sight: Dynamic DSA Reveals a Spectrum of Vertebral Artery Compression in Posterior Circulation Stroke – A Community-based Case Series (P1-4.012)

Key Points

• This research aims to describe the range of vertebral artery compression identified via dynamic DSA in patients with posterior circulation strokes that standard imaging could not evaluate.
• Community-based case series of patients
• Dynamic digital subtraction angiography used for assessment
• Inconclusive standard vascular imaging evaluated
• Dynamic DSA identified a range of vertebral artery compressions not seen in standard imaging.
• The findings suggest significant implications for diagnosing posterior circulation strokes.
