The textbook focuses on endovascular techniques for the treatment of cerebrovascular pathologies. It discusses specifically the anatomy of the human nervous system and how the influences of physiological factors, among which perivascular innervation and blood flow, could affect the endovascular approaches. The author then gives tricks on how to perform safely the main endovascular techniques and in which scenarios they should be used. Several chapters are then reserved for the discussion of the main drugs used in this field and which kind and dosages are recommended. The focus then moves on the main cerebrovascular pathologies (like aneurysms, cavernomas, ischemic stroke and so on). For each lesion, the author gives a general introduction and the main way to treat them. Each chapter is enriched by significant cases from author's experience.
