Based on the principles of functional vascular anatomy and endovascular treatment described in the first three volumes of Surgical Neuroangiography, Volumes 4 and 5 complete the series that takes a revolutionary approach in endovascular neurosurgery. The authors are world leaders, recipients of numerous prizes in medicine, and can offer the unique fruit of their combined anatomical, clinical and therapeutic experience to investigate and understand the disease process, its anatomical features and its relationship to patients' symptoms and treatment planning. Volume 4 is geared to track the vascular abnormalities of the brain; Volume 5 the vascular abnormalities of the spine and spinal cord. Both volumes identify the specifics of vascular lesions and set the interventional neuroradiological techniques before a background of proper clinical analysis and expertise. Each volume emphasizes the strategy and management objectives from an endovascular perspective taking into consideration a multidisciplinary approach where neurologists, neurosurgeons and neuroradiologists examine the clinical presentation, the diagnostic study and the therapeutic options in a joint decision-making process.
