This encyclopedic reference book on the treatment of intracranial aneurysms offers a case-based approach to the subject that has the benefit of fully reflecting the highly individual technical and clinical challenges encountered in aneurysm patients. The book is structured by aneurysm location, ensuring ease of use. Readers will find solutions for most clinical situations that they may encounter. Different treatment strategies are described, highlighting their respective pros and cons in particular circumstances. The coverage encompasses both basic techniques, such as coil occlusion and parent vessel occlusion, and the latest developments, including extra- and intrasaccular flow diversion, intrasaccular flow disruption, bifurcation stenting, and hybrid procedures combining microsurgical and endovascular elements. Potential procedural complications are identified, and bail-out strategies to anticipate, avoid, and solve major issues are described. The authors are all respected experts in the field, and the book will be of value to vascular and endovascular neurosurgeons, interventional neuroradiologists and neurologists, stroke neurologists, and other practitioners at all levels of experience.

Hans Henkes M.D. Ph.D., studied medicine and psychology at the Freie Universität Berlin and graduated in 1985. After residencies in neurophysiology and general radiology in Berlin, and in diagnostic neuroradiology in Homburg/Saar, he worked under Dietmar Kühne as an interventional neuroradiologist for 15 years at the Alfried Krupp Krankenhaus (Essen, Germany). In 2006 Dr. Henkes became an Extraordinary Professor for Neuroradiology at the University Duisburg-Essen, Germany. Since 2007 he has been the Medical Director of the Neuroradiological Clinic at the Klinikum Stuttgart, Germany. Dr. Henkes has co-authored more than 225 peerreviewed publications and serves as a reviewer for several journals including Stroke, AJNR, JNIS, Neurosurgery, Clinical Neuroradiology, Interventional Neuroradiology, and Neuroradiology. In 2013, he was awarded an honorary doctorate by the Dnipro State Medical Academy (Ukraine). In 2017, Dr. Henkes received the CIRSE Award for Excellence and Innovation in Interventional Radiology for the invention of stent-retriever thrombectomy in acute ischemic stroke.

Pedro Lylyk M.D. Ph.D., graduated from the Faculty of Medicine of the University of Buenos Aires (UBA). He completed his residency program in pediatric neurosurgery with Professor Raúl Carrea at the Ricardo Gutiérrez Children's Hospital of Buenos Aires. After that, Dr. Lylyk completed fellowships in diagnostic neuroradiology and therapeutic and endovascular neurosurgery at the University Hospital of London of the University of Western Ontario, Canada, and at the University of California, Los Angeles, USA. Among his extensive academic background, he is Chair of Neurosurgery and Hemodynamics at the University of Buenos Aires (UBA), Professor and Chair of the Department of Vascular Medicine at the Universidad del Salvador (USAL), Professor and Chair of Endovascular Surgery at the Universidad de Ciencias Sociales y Empresariales (UCES), and Director of Master Degrees in Neuroradiology and Hemodynamics Neurology, Diagnostic Imaging, and Kinesiology at the University of Buenos Aires (UBA). Dr. Lylyk is the founder and president of the FENERI Foundation (Fundación para el Estudio de las Neurociencias y la Radiología Intervencionista) and co-founder of the Cerebrovascular Research and Education Foundation (CREF) and the Intracranial Stent Meeting and Society (ICS). He is a member of the SwissNeuroFoundation and a founding member and former president of SILAN (Sociedad Iberolatinoamericana de Neurorradiología Diagnóstica y Terapéutica), AANDIT (Asociación Argentina de Neurorradiología Diagnóstica y Terapéutica), and CANI (Colegio Argentino de Neurointervencionistas). The endovascular lab at Clinica La Sagrada Familia is one of the training centers for SILAN fellows, which has allowed the training of more than 90 neuroendovascular professionals since 1995. Since 1986 Dr. Lylyk has been dedicated to the development and improvement of devices and therapeutic options to enhance the endovascular neurosurgical field and represents an international reference for the medical device industry.

Oliver Ganslandt M.D. Ph.D., studied medicine at the Friedrich-Alexander-Universität Erlangen, Germany. He completed his doctoral thesis in 1992 on magnetoencephalography and gained his Ph.D. ("Habilitation" grade) in 2002 in the subject of functional neuronavigation. His training as a neurosurgeon began in 1991 under Professor Fahlbusch at the Department of Neurosurgery Erlangen and later continued under Professor Buchfelder, where he worked as Vice Chairman of the department until January 2014. Dr. Ganslandt was then elected as Medical Director of the Neurosurgical Clinic of the Klinikum Stuttgart, Germany, where he works today. His clinical and scienti fic interests are functional imaging, neuro-oncology, and radiosurgery. Dr. Ganslandt has given numerous presentations at national and international meetings, serves as reviewer for many peer-reviewed journals (including Neurosurgery and Journal of Neurosurgery) as well as for national and international scienti fic organizations (Deutsche Forschungsgemeinschaft, Canada Foundation for Innovation, Dutch Cancer Society), and he is a member of the advisory board of the journal Strahlentherapie und Onkologie.
