Surgical Neuroangiography covers a variety of protocols and strategies combining functional vascular anatomy with a complete appreciation of the various disease processes, their pathophysiology, clinical presentation, and natural history, as well as recent technological advances. The newer endovascular techniques that apply to embolization of aneurysms, vascular malformations, and tumors of the spine, spinal cord, brain, and maxillofacial areas are reviewed. Implementing optimally efficient and safe strategies for occlusion or revascularization of arterial or venous structures requires the knowledge of collateral circulation covered in this volume. Berenstein, Lasjaunias, and ter Brugge, pioneers in the field with over 20 years of experience, present the new second volume of Surgical Neuroangiography, combining volumes 2, 4 and 5 of the previous edition.
