Book Synopsis Cerebral Blood Flow by : Mario Brock
Download or read book Cerebral Blood Flow written by Mario Brock and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a survey of some aspects of current knowledge on regional Cerebral Blood Flow (rCBF), mainly as studied by the isotope clearance method. Although both theoretical and methodological problems are discussed, attention is mainly dedicated to data obtained from clinical studies. The papers which make up this book were presented at the International Symposium on the Clinical Applications of Isotope Clearance Measurement of Cerebral Blood Flow, held in Mainz, Western Germany, on April 10-12, 1969. The previous meetings on Cerebral Blood Flow, held in Lund in 1964* and in Lund and Copenhagen 1968**, had shown that the moment had come to concentrate on the possibilities of introducing rCBF measurements into clinical routine. This is why in the Mainz Symposium attention was initially focused on methodological aspects. This is also why theoretical problems of physiology of CBF were not emphasized. Finally, this explains why such topics as cerebrovascular disease, head trauma, coma, carotid surgery, brain tumors and intracranial pressure were given pride of place. However a survey of the clinical aspects of rCBF measurements would not be complete without an account of the application of such measurements to monitor cerebral circulatory changes during anesthesia and therapeutic procedures like, for instance, hyperventilation and hyperbaric treatment. Furthermore, it is now possible to obtain data from correlative rCBF studies per formed before, during and after surgical operations on the human brain.

Book Synopsis The Cerebral Circulation by : Marilyn J. Cipolla
Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Cerebral Blood Flow And Metabolism: A Quantitative Approach by : Stephen John Payne
Download or read book Cerebral Blood Flow And Metabolism: A Quantitative Approach written by Stephen John Payne and published by World Scientific. This book was released on 2017-10-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the way in which the human brain is supplied with blood and how the brain uses this to provide nutrients, primarily oxygen and glucose, to brain cells in order to maintain healthy brain function. In particular, it focuses on the quantitative nature of blood flow and metabolism. The book covers models of blood flow and metabolism and how these can be measured using a variety of imaging and non-imaging techniques. It also examines how cerebral blood flow is controlled in response to a wide variety of challenges and how it changes with normal physiological variation and in response to a large number of pathological conditions, including stroke and dementia.As the first substantial book for over ten years in a fast-changing field, it highlights how the subject has progressed in the last couple of decades. It tackles the subject in a quantitative way, underlining its importance in both technical and clinical fields. Audiences with a technical or clinical background, especially researchers and postgraduate students in biomedical engineering or medicine, will find this a valuable read.
Book Synopsis Cerebral Blood Flow in Acute Head Injury by : Georg E. Cold
Download or read book Cerebral Blood Flow in Acute Head Injury written by Georg E. Cold and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade a multitude of studies concerning the dynamic changes in cerebral blood flow (CBF), cerebral metabolic rate of oxygen (CMRO2), and intracranial pressure (ICP) in the acute phase after head injury have been published. These studies have been supplemented with studies of cerebral autoregulation, CO2 reactivity and barbiturate reactivity. Other investigations include studies of cerebrospinal fluid pH, bicarbonate, lactate and pyruvate. In this book experimental and clinical studies of the dynamic changes in CBF, CMRO2, CO2 reactivity and barbiturate reactivity are reviewed. The author's own clinical studies of the dynamic changes in CBF and cerebral metabolism are summarized and discussed, and the therapeutical implication as regards the use of artificial hyperventilation, sedation with barbiturate and mannitol treatment are discussed.
Book Synopsis Cerebral Blood Flow by : Aldo Rescigno
Download or read book Cerebral Blood Flow written by Aldo Rescigno and published by Springer. This book was released on 1988 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Study Institute on "Cerebral Blood Flow: Mathematical Models, Instrumentation, and Imaging Techniques" was held in L'Aquila, Italy, June 2-13, 1986. Contributions to this program were received from the University of L'Aquila, Consiglio Nazionale delle Ricerche, Siemens Elettra S.p.A., and Bracco S.p.A. Recent studies of the cerebral blood circulation have lagged behind analysis of other parameters such as glucose utilization, transmitter distribution, and precursors. This Advanced Study Institute tried to fill this gap by analyzing in detail different physical techniques such as Autoradiography (including Double-Tracer Auto radiography and highly specific tracers as Iodoantipyrine, Micro spheres), Single Photon Emission Computed Tomography, Nuclear Magnetic Resonance. Each method was analyzed in regards to its precision, resolution, response time. A considerable part of this Institute was devoted to the mathematics of CBF measurement, in its two aspects, i.e. the modeling of the underlying kinetic system and the statistical analysis of the data. The modeling methods proposed included the development of a differential algebra whereby the differential and integral equations involved could be solved by simple algebraic methods, including graph theoretical ones; the statistical methods proposed included the illustration of different parametrizations of possible use in the interpretation of experimental results.

Download or read book The Cerebral Veins written by L.M. Auer and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in the morphology-angioarchitecture and ultrastructure-of cerebral veins has been widely neglected in past decades; investigation was mainly focussed on the arterial side of brain circulation. This circumstance has certainly had a negative impact on the development of knowledge in clinical medicine about cerebral venous disease. Cerebra} venous pathology and its consequence is, however, a frequent problern in clinical neurosur gery, both with regard to operative techniques and conservative manage ment. Therefore, it is not surprising that the initiative to collect, for the first time, data on our present knowledge in basic research of cerebral veins, their structure and function under normal and pathological circumstances, came from clinicians. Regarding the cerebral veins the clinician has primarily in view the dysfunctions originating from embryogenetic malformations, phlebitic obstruction, tumourous shunts, or traumatic lesions. But in addition to that, particular attention should be paid to the microstructure ofthe venous vessel walls, their barrier function, and the venous vasomotor system. Studying these interrelationships has for a long time been both fascinating and of immediate interest to me.

Book Synopsis Monitoring of Cerebral Blood Flow and Metabolism in Intensive Care by : Andreas Unterberg
Download or read book Monitoring of Cerebral Blood Flow and Metabolism in Intensive Care written by Andreas Unterberg and published by Springer. This book was released on 2012-02-28 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, monitoring of cerebral blood flow and metabolism was an unattained goal. Determination of cerebral blood flow was limited to intermittent measurements and particularly difficult to perform in critically ill patients. Meanwhile there are techniques available, however, to monitor cerebral blood flow and cerebral oxygenation, both globally and regionally. Therefore we thought it worthwhile to discuss these new continuous techniques and to compare them with well-known techniques which discontinuously measure CBF. For that purpose, an international workshop with some leading experts in the field was held in October 1992 in Berlin. The workshop consisted of about 20 lectures, either reviews on a special topic, or latest results. These contributions were given by invitation and were extensively discussed. Unfortunately it is impossible to reproduce the discussions. On the other hand, all speakers delivered a manuscript promptly after the meeting so that we were able to edit them within a short time. Since monitoring of cerebral blood flow in intensive care is a rapidly growing and changing topic, the written contributions should be quickly available. Authors, editors and publishers have tried to come close to this ideal. As editors we would like to thank the authors and the publishers who enabled us to come out with this volume of the proceedings as early as possible.
