Objective:
To describe three cases of migraine (two with aura) after an intracranial endovascular procedure. Method.-Retrospective.
Results:
One patient had an attack of migraine with prolonged aura after embolization of a dural arteriovenous fistula. Another patient had an attack of migraine with aura (and hemiparesis) after a diagnostic angiogram. The third patient already suffered from migraine with aura and had a migraine attack after embolization of an occipital arteriovenous malformation. A quadrantanopia persisted in this patient. Outcome of the other two patients was good.
Conclusion:
Intracranial endovascular procedures can induce migraine with aura. We could not identify the underlying pathophysiological mechanism, but mechanical, chemical, immunological, or hemodynamic factors could be involved.
Insights
Intracranial endovascular procedures may trigger migraine with aura, a neurological condition. Further research is needed to understand the exact causes of this association.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Medicine
Background:
- Intracranial endovascular procedures are common interventions for cerebrovascular diseases.
- Migraine with aura is a complex neurological disorder characterized by transient neurological symptoms preceding a headache.
Observation:
- This study details three cases where patients developed migraine with aura following intracranial endovascular procedures.
- Two cases involved migraine with aura after embolization of arteriovenous fistulas or malformations, and one after a diagnostic angiogram.
- One patient experienced persistent visual field defects (quadrantanopia) post-procedure.
Findings:
- Intracranial endovascular procedures appear to be a potential trigger for migraine with aura.
- The precise pathophysiological mechanisms remain unclear, but potential factors include mechanical, chemical, immunological, or hemodynamic influences.
Implications:
- Clinicians should be aware of the potential for migraine induction after endovascular procedures.
- Further investigation into the mechanisms underlying procedure-induced migraines may inform preventative or therapeutic strategies.
