This book was released on 2013-06-29 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written by an author whose knowledge of the subject is based on vast surgical experience. A reliable assessment of the success or failure of a micro vascular anastomosis or an aneurysm operation has until now been possible only postoperatively by angiography and transcutaneous Doppler sonography. Of particular impor tance are the stenoses and occlusions which can occur dur ing the operation, but which are frequently not detected un til after surgery. This induced the neurosurgeons in Freiburg, as well as those in several other hospitals, to carry out a rou tine control with postoperative transcutaneous Doppler fol lowing extracranial-intracranial bypass operations and an giography while still under anesthesia following aneurysm operations. The stenoses and occlusions detected were often not apparent intraoperatively. The reasons for this are that from the outside we see only the surface - and not the lu men - of a v~ssel, and that stenoses caused by thrombosis, indentation of the vessel wall during anastomosis or by plaque on the vessel wall are not externally obvious. Even arterial pulsation is no guarantee of patency. The necessity to be able to detect stenoses during the op eration is obvious. The microvascular Doppler sonography adopted by Dr. Gilsbach provides an expedient and safe method of recognizing such lumen narrowings.
Book Synopsis Neurosurgical Applications of Transcranial Doppler Sonography by : A. Harders
Download or read book Neurosurgical Applications of Transcranial Doppler Sonography written by A. Harders and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1981, the Norwegian physiologist and cyberneticist, Rune Aaslid, developed a device which made it possible to apply the transcranial Doppler sonographic technique in man. In 1983, Dr. Albrecht Harders took on the project of working out a clinically practicable method that would allow atraumatic measurements to be made of the blood flow velocity in the large branches ofthe circle of Willis. The technique has now become a competitor of the conventional methods of measuring the intracranial hemodynamics, including angiography and the xenon method of cerebral blood flow measurement. Harders proceeded from the assumption that the measurement of the blood flow velocity is more relevant for clinical diagnoses than the usual volume flow measurements. He stresses the very valuable application of the technique in detecting cerebral vasospasm before and after aneurysm surgery. The changes in the blood flow velocities measured by transcranial Doppler sonography in the individual vessel segments of the circle of Willis are interpreted with respect to the various factors that can effect such changes (collateral circulation in the circle of Willis, diameter of the vessel, vascular resistance, the general cardiovascular situation, arterial partial CO pressure, autoregulatory factors, position of body). The rate of 2 complications associated with angiography has thus been reduced, since the best time both for angiography and for surgery can be determined, and continuous TCD examinations show when the patient is out of a critical phase of cerebral vasospasm.
Book Synopsis Intraoperative Ultrasound (IOUS) in Neurosurgery by : Francesco Prada
Download or read book Intraoperative Ultrasound (IOUS) in Neurosurgery written by Francesco Prada and published by Springer. This book was released on 2016-03-08 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a practical manual on the use of intraoperative ultrasound (IOUS) as a tool for imaging guidance during cranial and spinal neurosurgical procedures. Full account is taken of the emergence of novel clinical applications and recent technical advances, with extensive coverage of the impact of developments such as improved probe technology, fusion imaging and virtual navigation, 3D ultrasound imaging, contrast-enhanced ultrasound, and elastosonography. Basic principles of ultrasound are elucidated in order to assist in the optimal use of IOUS and clear guidance is provided on the interpretation of imaging findings in various pathologies. Informative comparisons are also made of the use of techniques such as fusion imaging and contrast-enhanced ultrasound in general radiology and neurosurgery. The aim of the authors is to enhance the general knowledge regarding intra-operative ultrasound brain imaging, standardizing its use and exploring new techniques, leading in some way toward compensating the lack of specific training in the application of ultrasound among the neurosurgical community. IOUS is a sensitive tool that can improve surgical precision and help to reduce morbidity.

Book Synopsis Atlas of Color-Coded Doppler Sonography by : Franz X.J. Frühwald
Download or read book Atlas of Color-Coded Doppler Sonography written by Franz X.J. Frühwald and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: For those of us who have been associated with the field of ultrasound imaging of the arterial system since its infancy, this contribution by Friihwald and Blackwell provides the source where the results of over 30 years of hard-won advances can be found. The editors and contributors summarize this burgeoning field in their lucidly written, interesting, and accurate treatise. Beginning with chapters on physical principles and technical considerations, including how to adjust equipment for best images, they consider forthwith carotid and vertebral disease in two outstanding chapters with color images of startling defini tion. Also included are diagrams in which vascular structures are clearly related to well-labeled anatomical landmarks. No other atlas contains the quality of color images and graphic displays which these two editors have compiled. Now that surgical remediation of stenosis of the extracranial carotid and, perhaps, also the vertebral arteries has been demonstrated effective there will undoubtedly be an explosion in the use of this advanced technology to identify appropriate patients and to follow lesions longitudinally over time. To accomplish this, high-quality images made by skilled sonogra phers are the vital component and this book sets standards in this domain.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the introduction of electrosurgery the techniques of surgery on the nervous system have passed through further improvements (bipolar coagulation, microscope), even if the procedure was not substantially modified. Today, laser represents a new "discipline", as it offers a new way of performing all basic maneuvers (dissection, demolition, hemostasis, vessel sutures). Furthermore, laser offers the possibility of a special maneuver, namely reduction of the volume of a tumoral mass through vaporization. Its application is not restricted to traditional neurosurgery but extends also to stereotactic and vascular neurosurgery. Laser surgery has also influenced the anesthesiologic techniques. At the same time new instrumentation has been introduced: CUSA ultrasonic aspiration, echotomography, and Doppler flowmeter. I have had the chance to utilize these new technologies all at a time and have come to the conclusion that we are facing the dawn of a new methodology which has already shown its validity and lack of inconveniences, and whose object is to increase the precision of neurological surgery. The technological development is still going on, and some improvements are to be foreseen. Laser scalpel is splitting the initial laser surgery into NO TOUCH and TOUCH surgery with laser. As new instrumentarium will be developed, a variable and tunable beam will become available. For example, in a few years Free Electron Laser will further add to the progress in this field.

Book Synopsis Pediatric Applications of Transcranial Doppler Sonography by : Harald Bode
Download or read book Pediatric Applications of Transcranial Doppler Sonography written by Harald Bode and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Handbook of Transcranial Doppler written by John P. McCartney and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transcranial Doppler (TCD) ultrasound, first introduced more than a decade ago, has steadily evolved into a dynamic, reliable, reproducible, and practical diagnostic tool. Clinical neuroscientists have found TCD to be an indispensable technique in the management of many types of patients. This book is designed to provide basic instruction in the perfor mance and interpretation of transcranial Doppler ultrasonography for technologists, nurses, and physicians. The information included in the text is critical for the development of a strong knowledge base. It is not intended to be all inclusive, and the TCD novice is likely to use it as the platform upon which to build his/her experience in the application of TCD. This book is organized as a step-guided approach for the performance of TCD, and it includes specific guidelines for interpretation of the TCD save forms. We hope that the reader finds it useful during what we think is the most difficult phase of this technique-the learning curve. John P. McCartney, R.V.T. Kathleen M. Thomas-Lukes, R.N., M.N.
