Book Description
This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

Book Description
Traumatic brain injury (TBI) remains a significant source of death and permanent disability, contributing to nearly one-third of all injury related deaths in the United States and exacting a profound personal and economic toll. Despite the increased resources that have recently been brought to bear to improve our understanding of TBI, the developme

Book Description
Every few years a dissertation comes to the area of clinical application of medical technology which carries us forward as on a magic carpet into new regions of understanding and patient care. This book is such a magic carpet. It brings together, in a clear and incisive fashion, important hemodynamic principles with a simple noninvasive method of application to a part of the cerebral vasculature which has been relatively inaccessible. To the lucky and perceptive person who reads this book, a feeling of excitement and hope for progress is engendered. The diligent application of the potentials of transcranial Doppler ultrasound brings new power to our efforts in understanding the cerebral circulation and the causes, treatment and prevention of cerebrovascular disorders. Merrill P. Spencer, M. D. Director Institute of Applied Physiology and Medicine Seattle, Wash. , July 1986 Acknowledgements I am greatly indebted to Prof. He1ge Nornes, Oslo, who introduced me to the fascinating study of cerebral hemodynamics in the early 1970's and since then continually encouraged my interest in this field. It was through his pioneering work on the cerebral circulation-using peroperative electromagnetic flowmetry and Doppler techniques-that the basis was laid for the noninvasive trans cranial approach to the circle of Willis described in this book. I also gratefully acknowledge the stimulating case discussions with Prof. Peter Huber, Berne, at the very early introduction of trans cranial Doppler, the inspiring exchange of ideas with Dr. Merrill P.

Book Description
New and groundbreaking therapeutic options for the critical care of patients with cerebrovascular disease have improved patient management, minimized morbidity, reduced in-patient care, improved quality of life, and had a positive economic impact on health service provision. This volume integrates these approaches and suggests the best therapy option for all cerebrovascular conditions. The early chapters of the book focus on monitoring techniques and interventions. Subsequent sections address the critical care of a wide range of cerebrovascular diseases: ischemic stroke, intracranial hemorrhage, subarachnoid hemorrhage, arteriovenous malformations, cerebral venous thrombosis and traumatic injury. The editors and authors are internationally recognized experts in their field, and the text is supplemented by tables and illustrations to demonstrate important clinical findings. This book will meet the needs of stroke physicians, neurologists, neurosurgeons, neurointensivists and interventional neuroradiologists seeking to maximize positive outcomes for their patients.

Book Description
Advances in Neurosurgery presents the experience and research results of modern neurosurgeons confronted with urgent diagnostic and therapeutic problems. The first topic here is spontaneous intracerebral hematomas, whose localization determines the form of treatment and usually its outcome. Newer therapeutic approaches such as stereotactic removal, endoscopy and fibrinolysis supplement the results of standard operative methods. Secondly, the hydrocephalus malresorptivus is covered, presenting experience with the diagnostic value of intrathecal infusion tests, CT-cisternography, evoked potentials, and MRI CSF-flow studies, as well as aspects of neurosurgical intensive care such as barbiturate treatment, respiratory problems in head injury patients, auto-regulation mechanisms, and hospital infection. The last section is devoted to peripheral nerve surgery, reports on experience with microsurgery and various forms of anastomosis in both traumatic and tumorous nerve lesions.

Book Description
Nearly 80 short papers originating from the 14th International Symposium on Intracranial Pressure and Brain Monitoring held in Tuebingen, Germany, in September 2010 present experimental as well as clinical research data related to the naming topics of the conference. The papers have undergone a peer-reviewing and are organized in the following sections: methods of brain monitoring and data analysis, methods of invasive and non-invasive ICP assessment, the role of autoregulation, the role of tissue oxygenation and near-infrared spectroscopy, hydrocephalus/IIH imaging and diagnosis, management and therapy of hydrocephalus, management and therapy of traumatic brain injury, management and therapy of subarachnoid and intracranial hemorrhage, experimental approaches to acute brain disease. The book gives a good overview on the latest research developments in the field of ICP and related brain monitoring and on management and therapy of relevant acute brain diseases.

Book Description
Vascular malformations of the brain and spine pose many management challenges. This text provides a comprehensive, state-of-the-art review of the natural history, treatment options, and outcomes of patients with these conditions. Despite their relative rarity, these lesions are responsible for devastating injury to individuals and can cause an enduring physical, psychological, and economic burden on patients and families. Many new therapeutic options are now available with the advent of novel surgical, endovascular, and radiosurgical techniques. The basic sciences have fuelled development of small molecule and biologic therapies targeting the molecular basis of disease. Authored by international experts in the fields of neurosurgery, neurology, radiology, and radiation oncology, this book provides state-of-the-art treatment plans and discussions of ideal therapy. This text is aimed at practitioners in the fields of neurology, neurosurgery, neuroradiology, radiation oncology, rehabilitation medicine and allied fields who care for patients with brain and spinal vascular malformations.
