Intraoperative Doppler Sonography in Neurosurgery by J.M. Gilsbach Pdf

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.

Neurosurgical Applications of Transcranial Doppler Sonography by A. Harders Pdf

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.

Intraoperative Ultrasound (IOUS) in Neurosurgery by Francesco Prada,Luigi Solbiati,Alberto Martegani,Francesco DiMeco Pdf

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.

Intraoperative Ultrasound Imaging in Neurosurgery by Ludwig M. Auer,Vera Van Velthoven Pdf

Intraoperative ultrasound is the first and, at present, only direct method available for depicting cerebral structures during neurosurgery. This atlas is a practical introduction to intraoperative ultrasound in neurosurgery and a guide to anatomy and pathomorphological diagnosis. A short introduction to the technical basis of ultrasound is given first. It is followed by instructions for practical application of the method in the operating theater. The next, comprehensive chapter presents various intracranial pathomorphological changes in the ultrasound picture and compares them to the familiar computer tomography and MRI images. A separate chapter deals with individual aspects of actual application during neurosurgical operations: ultrasound biopsy, puncture and endoscopy. This volume is an excellent source of information for the practical application of intraoperative ultrasound.

Transcranial Doppler Sonography by Rune Aaslid Pdf

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.

Modern Methods in Neurosurgery by Wendelin Walter,Mathias Brandt,Mario Brock,Margareta Klinger Pdf

This 16th volume of Advances in Neurosurgery contains a selection of pa pers presented at the 38th Annual Meeting of the German Society of Neurosurgery, held in Munster on 3-6 May 1987. The program committee had to choose these contributions from a total of 161 presentations. I am very much obliged to the members of the committee who contributed their experience and effort to the organization of the scientific pro gram: Prof. Dr. R.A. Frowein, Prof. Dr. W.J. Bock, Prof. Dr. E. Kazner, Prof. Dr. G. Lausberg, Prof. Dr. M. Klinger, and Prof. Dr. M. Brandt. The aim of the Meeting was to exchange experiences regarding modern diagnostic and therapeutic achievements. The first main topic was new technical methods in neurosurgery. Refinements in laser technology were introduced; different laser devices have been recognized as use ful tools in microsurgery and some peripheral nerve problems. The Ca vitron ultrasonic aspirator has proven its value in a great variety of intracranial and spinal tumors within a few years. Its technical advance is impressively demonstrated by some of the papers in this book. With growing experience we have recognized the great value of these additional instruments in limited surgical fields and learned not to overestimate them in the hands of a skilled neurosurgeon.
