Volume-Staged Radiosurgery for Large Arteriovenous Malformation

Large arteriovenous malformations (AVMs) are challenges in management because of outcomes and adverse affects. Volume-staged radiosurgery has been an appropriate approach when removal resection and embolization are not recommended. A 53-year-old gentleman was diagnosed with a large intracranial AVM with persistent headache and short-term seizure. Brain magnetic resonance and angiograph showed a bulky volume of AVM nidus. Removal resection and embolization were not recommended because of high risk of adverse affects. The patient was treated by volume-staged radiosurgery. One year post-treatment, obliteration for right internal carotid artery was completed. Volume-staged radiosurgery is a potential treatment option for large AVM with controlled and obliteration efficacy, especially to AVMs which are not appropriate for removal surgery and embolization.
