For the first time in the history of medicine, advances in technology have outpaced our ability to apply them in the clinical setting. With the likelihood of rapid change in the healthcare arena, a more critical question emerges in the adoption of new technology, which is what should we be doing with it. The brain remains the last frontier in medicine where we still lack a full understanding of its function and vast neural network. This allows for a perfect union of technology and discovery to contribute to better outcomes and develop cures for disorders of the nervous system. The ability to access virtually every area of the brain via the cerebrovasculature has never been more important. This text presents new technological advances in a comprehensive and balanced way. As we have learned countless times in modern medicine, new is not always better and in fact may be deleterious. The ability to assess newer techniques in a way that is always in the patients best interest is the ultimate goal. Leaders in the field of vascular neurosurgery discuss new technologies as well as their controversies, from neurointervention and embolic protection devices to robot-assisted endovascular intervention and precision surgery for aneurysms. The result is an unbiased and comprehensive picture of the latest innovations in cerebrovascular surgery and the manner in which they are applied in the clinical setting. Advanced Technologies in Vascular Neurosurgery focuses on new procedures and technology as opposed to the traditional and stale “clip vs. coil� discussions. It the first discussion of artificial intelligence and robotics in vascular neurosurgery in text.
