Background: Migraine is associated with cervical artery dissection (CeAD). Calcitonin gene-related peptide (CGRP) is a multifunctional neuropeptide with vasodilatory effects. The use of anti-CGRP monoclonal antibodies (CGRP mAb) may affect cerebrovascular disease risk; however, no reports have associated CGRP mAb with CeAD.
Case presentation and faers database analysis: We report a case of vertebral artery dissection in a 39-year-old woman with migraine treated with galcanezumab. We searched the number of cases where cerebral and cervical artery dissection were reported as adverse effects of CGRP mAb using the FDA Adverse Event Reporting System (FAERS) database. Six and ten such cases were reported regarding galcanezumab and CGRP mAbs use, respectively. The reporting odds ratios for galcanezumab and CGRP mAbs were elevated.
Conclusion: Although migraine is reported to be associated with CeAD, the use of CGRP mAb might be related to CeAD and warrant further investigation.
