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.

Volume-staged versus dose-staged stereotactic radiosurgery, with or without embolization, in the treatment of large brain arteriovenous malformations: A systematic review and meta-analysis.

Background And Objective: While safe and effective modalities exist to treat small arteriovenous malformations (AVMs), large (>10 cm) AVMs remain difficult to cure via surgical or endovascular means. Staged stereotactic radiosurgery (SRS), either volume-staged (VS) or dose-staged (DS), has been proposed for large AVMs. The relative efficacy of these two strategies, with or without endovascular embolization, is unclear.

Stereotactic radiosurgery (SRS) is an effective treatment strategy for cerebral arteriovenous malformations (AVMs). Aggressive treatment achieving complete obliteration is necessary to prevent further intracranial hemorrhage and neurological deficits. However, SRS treatment of large AVMs (>10 cm) is challenging.

Background: Stereotactic radiosurgery (SRS) represents a minimally invasive and valuable alternative for jugular foramen schwannomas (JFS), both as upfront and/or adjuvant treatment (in hybrid approaches).
Methods: We conducted a retrospective review of our cases treated at the Lausanne University Hospital (CHUV) from June 2010 to October 2023. Eleven patients underwent SRS, among whom three had prior surgery, two in our center in the frame of a planned combined approach and one in another center.

Background And Objectives: Although stereotactic radiosurgery (SRS) has well defined outcomes in the management of smaller-volume arteriovenous malformations (AVM), this report evaluates the outcomes when SRS is used for large-volume (≥10 cc) lobar AVMs.
Methods: Between 1990 and 2022, a cohort of 1325 patients underwent Leksell Gamma Knife SRS for brain AVMs. Among these, 40 patients (25 women; median age: 37 years) with large lobar AVMs underwent volume-staged SRS followed by additional SRS procedures if needed (2-5 procedures).

We report the case of a 29-year-old man who presented with a sudden headache. Computed tomography showed a small intraventricular hemorrhage in the left lateral ventricle. Cerebral angiograms suggested rupture of a coexisting feeder aneurysm in the left temporal cerebral arteriovenous malformation (AVM).
