Book Description
Negative influence of cerebral circulation with the emergence of cerebral hypoperfusion plays a significant role in the pathophysiology of pediatric hydrocephalus. Transcranial Doppler sonography is a non-invasive method for indirectly measuring intracranial pressure and decreasing intracranial compliance by assessing changes of cerebral circulation. This book discusses the cerebral circulation and intracranial dynamics in pediatric hydrocephalus. It also focuses on evaluating the impact of various intracranial factors on Doppler parameters of cerebral circulation, especially in neonates with hydrocephalus. The ambition of this work is to improve indication and timing of drainage procedure in children with hydrocephalus by applying scientific results and clinical experience.

Book Description
The measurement of the cerebral circulation in children, particularly in newborns and young infants, has for a long time been high on the list of needs in clinical and scientific pediatrics. The methods available to date have either been too unreliable or unsuitable for use on children. In the course of a research project at the Department of Pediatrics of the Uni versity of Freiburg, Dr. Harald Bode has made the first systematic ex amination of the cerebral circulation of children using transcranial Doppler sonography. Over 500 children with ages between 0 and 18 years were included in this exhaustive study, documenting Doppler measurements in about 3,000 basal cerebral arteries. Basic reference values were obtained which involved adapting the methodology and available equipment to the special re quirements of the pediatrician. Moreover, the influence of biological and physiological factors on these Doppler values has also been considered in addition to those of disease and therapy. The result is an impressive record of the many applications of trans cranial Doppler sonography during childhood. It is not difficult to predict that this methodology will be of lasting value and capable of further de velopment. I hope this book receives the attention it undoubtedly deserves and that the author is able to continue in realizing his fruitful scientific ideas in clinical pediatric practice.

Book Description
Active, progressive hydrocephalus in children leads to increase of intracranial pressure, dilatation of cerebral ventricles, and decrease of intracranial compliance. These changes lead to disorder of regulation of cerebral circulation and development of cerebral hypoperfusion resulting in the secondary brain damage. Ependymal disruption, periventricular edema, and compression of the periventricular capillaries can be developed. Ischemia of the white matter can be developed due to hypoperfusion. But it is reversible if treated early and adequately. Transcranial Doppler sonography enables to determine hemodynamic parameters of cerebral circulation in various physiological and pathophysiological conditions. As transcranial Doppler sonography has been regarded to be noninvasive and appropriate for bedside treatment, it can also be applied in children at any age. The goal of this chapter is to assess changes of cerebral circulation in children with hydrocephalus and application of data from scientific studies of intracranial dynamics in children with hydrocephalus in clinical practice. The work is also focused on evaluation of impact of intracranial factors on Doppler parameters of cerebral circulation, especially in neonates with hydrocephalus. The ambition of this chapter is to improve indication and timing of drainage procedure in children with hydrocephalus by application of the results and clinical experience in daily clinical practice.

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
This book is a comprehensive overview of spina bifida and craniosynostosis with emphasis on new trends in the management of these diseases. Chapters on spina bifida cover such topics as the etiology and pathophysiology of caudal neural tube defects, the overall management of pediatric patients with spina bifida, surgical treatment, and urological and orthopedic care. The chapters on craniosynostosis present new technologies of surgical treatment, craniomaxillofacial corrective surgery, and telescoping techniques with multiple cranial osteotomies.

Book Description
Description of hydrocephalus can be found in ancient medical literature from Egypt as old as 500 AD. Hydrocephalus is characterized by abnormal accumulation of cerebrospinal fluid (CSF) in the ventricles of the brain. This results in the rise of intracranial pressure inside the skull causing progressive increase in the size of the head, seizure, tunneling of vision, and mental disability. The clinical presentation of hydrocephalus varies with age of onset and chronicity of the underlying disease process. Acute dilatation of the ventricular system manifests with features of raised intracranial pressure while chronic dilatation has a more insidious onset presenting as Adams triad. Treatment is generally surgical by creating various types of cerebral shunts. Role of endoscopic has emerged lately in the management of hydrocephalus.
