Headache and Visual Aura Outcomes After Stereotactic Radiosurgery for Patients With Occipital Lobe Arteriovenous Malformations: A Single-Center Retrospective Cohort Study.
Background and objectives: Patients with brain arteriovenous malformations (BAVMs) sometimes experience migraine-like chronic headaches. Reportedly, this symptom is common in occipital lobe BAVMs; however, the exact prevalence has not been clarified, and the details of visual auras have been scarcely reported. Furthermore, no comprehensive studies exist on the improvement of migraine associated with visual auras in occipital lobe BAVMs after stereotactic radiosurgery (SRS). Therefore, this study investigated the prevalence of headache with visual aura in patients with occipital lobe BAVMs and evaluated the impact of SRS on preexisting symptoms.
Methods: As a single-center retrospective cohort study, a total of 104 patients with occipital lobe BAVMs treated with SRS from 1990 to 2024 were analyzed. Pre-SRS and post-SRS symptoms of headache and visual aura were documented. The outcomes measured were headache severity, frequency, aura characteristics, and BAVM obliteration rates.
Results: Of the 104 patients, 41 (39%) reported chronic headache pre-SRS, and 37 (36%) experienced migraine with visual aura. Compared with pre-SRS, 90% (28/31) of the patients experienced a >50% reduction in headache severity and frequency at a median follow-up of 11 months, and 89% (25/28) experienced a >50% reduction in aura frequency. Complete headache remission was achieved in 35% (13/31) of patients. Complete obliteration of BAVMs was confirmed in 75% (76/102) of the patients at a median of 33 months. A smaller nidus volume was associated with both complete headache remission and BAVM obliteration, whereas age and sex were not significant predictors of headache outcome.
Conclusion: Patients with occipital lobe BAVMs frequently experience migraine-like headaches with visual aura, which may be more prevalent than in the general population. SRS for occipital lobe BAVMs could not only achieve favorable BAVM obliteration with minimal adverse effects but also significantly improve migraine-like symptoms, including visual aura, particularly in patients with smaller nidus volumes.
