Management of Spinal Cord Tumors and Arteriovenous Malformations

Although spinal cord tumor and spinal cord arteriovenous malformation (AVM) operations may appear to be unrelated, they are, in fact, closely linked. Both tumors and AVMs are space-occupying lesions, present challenging technical scenarios, and require an understanding of their natural history to pursue the wisest course of treatment. Addressing the mass lesion while preserving blood supply to the spinal cord is a goal in treating both tumors and AVMs. As a result of advanced magnetic resonance imaging, angiography, endovascular techniques, and neurophysiologic monitoring, more aggressive surgeries can safely be performed, with improved outcomes relative to the earliest reports.
