This book on the anatomy of central nervous system arteries concentrates on all anatomical variations of the central nervous system and it describes the embryological processes that hide behind the possible adult variants. The first section of the work is a reminder of general concepts of embryology. After that, each section corresponds to arteries of an anatomical location: intradural, dural, skull base and cranio-cervical junction. Each chapter is dedicated to a single artery to facilitate the reader’s search for information. In addition, modern and detailed illustrations of the embryological steps and adult variants are included. There are two types of illustrations: artist’s drawing, usually to explain the vascular embryology, and angiographic images. The central point of the book lies in the space devoted to the embryological development of each artery and the processes that can lead to the development of different variants in the adult. The audience of this bookis aimed at neurosurgeons and neuroradiologists, specialists in the neurovascular area, but it will also help residents in neurosurgery, neuroradiology and neurology in their daily practice.
