Summary
Radiosurgery effectively treats headaches in most patients with cerebral arteriovenous malformations (cAVMs). Headache relief is often linked to successful cAVM obliteration, indicating radiosurgery benefits both conditions.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Context:
- Cerebral arteriovenous malformations (cAVMs) are complex vascular abnormalities.
- Headaches are a common symptom associated with cAVMs.
- Radiosurgery is a treatment modality for cAVMs.
Purpose:
- To evaluate headache response after radiosurgery for cAVMs.
- To identify factors predicting positive headache outcomes.
- To explore the relationship between headache resolution and cAVM obliteration.
Summary:
- This study analyzed 109 patients with cAVMs treated with radiosurgery.
- Headaches resolved in 53.7% and decreased in 20.3% of patients.
- Headache disappearance was associated with unilateral presentation, specific locations (parietal, rolandic), and preceded epileptic seizures.
Impact:
- Radiosurgery demonstrates a positive impact on headaches associated with cAVMs.
- Headache resolution often correlates with successful cAVM obliteration.
- Findings suggest a direct link between cAVMs and headaches, both benefiting from radiosurgery.
