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)
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)
The cosmetic result, cost effectiveness, and complication rate of three different types of skin closure: staples, tapes, and interrupted nylon were compared. In 68 wounds, skin closure was randomized to staples, tapes, or interrupted 3/0 nylon sutures. All wounds were closed subcutaneously with interrupted undyed 2/0 dexon. For 3 months, 59 wounds were(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)
The results of excision arthroplasty on forty hips in thirty-two patients have been studied by personal review. The mean follow-up was ten years and the results were graded in the Lazansky system. The outcome was fairly predictable, most patients achieving a fair to good result. The patients were satisfied with the operation in unilateral cases as a(More)
Recurrence along an endoscope tract has been described after endoscopic biopsy and resection of malignant tumors arising in multiple organ systems. We describe a case of tract recurrence following the ventriculoscopic biopsy of a central nervous system tumor. A retrospective review of the patient's clinical course, radiology and pathology was undertaken to(More)
PURPOSE To investigate predictive factors in the development of symptomatic radiation injury after treatment with linear accelerator-based stereotactic radiosurgery for intracerebral arteriovenous malformations and relate the findings to the conclusions drawn by Quantitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC). METHODS AND MATERIALS(More)
A segment of tibia 4.5 centimetres long was removed from one hind limb of fifteen dogs. It was then replaced and the main vasculature was restored by a microsurgical technique. In eight controls the segment was replaced without such restoration. In two-thirds of the former cases the microvascular reconstruction was successful; the rate of infection was(More)
