OBJECT The goal of this study was to determine the rates of mortality and morbidity associated with the embolization of arteriovenous malformations (AVMs) of the brain and to analyze the factors related to embolization-related complications. METHODS The University of Toronto Brain Vascular Malformation Study Group database was reviewed. Three hundred six(More)
BACKGROUND Superior cerebellar artery aneurysms are rare. We present a clinical series of twelve of these aneurysms that were treated exclusively with endovascular coils. METHOD A retrospective analysis of a prospectively collected database of cerebral aneurysms treated with coil embolization was performed. Clinical notes and radiological images were(More)
There are multiple transvenous approaches for treatment of cavernous dural arteriovenous fistulae (DAVF). The choice of a specific route depends on the compartment of the cavernous sinus involved in the fistula and its venous drainage. We used two different facial vein approaches to treat patients with cavernous DAVF draining directly into the anterior(More)
OBJECTIVE To investigate predictive factors of complete obliteration following treatment with linac-based stereotactic radiosurgery for intracerebral arteriovenous malformations. METHODS Archived plans for 48 patients treated at the British Columbia Cancer Agency and who underwent post-treatment digital subtraction angiography to assess obliteration were(More)
Many embolization procedures have been described for the treatment of cavernous dural fistulas, including direct superior ophthalmic vein cannulation. Sometimes thrombosis of the superior ophthalmic vein or an anatomic variant will not allow its cannulation. Herein, we describe a case of a cavernous dural fistula in which an anteriorly narrowed and(More)
BACKGROUND Medulloblastoma is the most common malignant central nervous system tumour in children but, in contrast, quite rare in adults. Hemispheric, rather than midline, cerebellar medulloblastomas are more common in older children and adults. We present the unusual case of a 71-year-old man who presented with a fourth ventricular mass that proved to be a(More)
