Finding fibrillin in cerebral artery dissection

Cerebral artery dissection (CeAD) is an important cause of stroke, particularly in the young. Identifying cerebral dissection benefits patients because it affects management, influences follow-up investigations, and may prompt evaluation for associated conditions such as connective tissue disease.1 Making the diagnosis of arterial dissection requires appropriate vascular imaging combined with an index of suspicion. However, a blood-based biomarker may have a role in identifying arterial dissection, defining its stage and severity, and guiding follow-up investigations for complications.
