Over the past 15 years, mechanical valves, and in particular, bileaflet mechanical valves, have made considerable strides in durability and hemodynamic per- formance. However, biocompatibility in terms of thrombo- embolism, thrombosis, and hemolysis has remained an area where improvement is needed. "New Development in Bileaflet Mechanical Heart Valve" discusses advances in these important areas of prosthetic valve function and provides clinical experience with a new open pivot, bileaflet mechanical valve.

Coronary heart disease is one of the major health problems in indus trialized nations because of its high incidence and severity. Recent innovations in medical and surgical treatment of coronary heart dis ease have increased the importance of accurate diagnostic methods for determining the severity of coronary disease, identifying potential treatment alternatives, and evaluating the results of treatment. Great advances have also been made in basic research on coronary circula tion and its interaction with myocardial contraction and relaxation and neural and humoral control. With respect to these developments, the papers included in the present monograph deal with important topics concerned with the basic mechanism of coronary circulation as well as ones of clinical relevance. It is directed toward physicians (cardiologists, cardiac surgeons, cardiac radiologists, anestheologists, and others) and basic scientists (e.g., physiologists, bioengineers). We would like to em phasize the importance of a multidisciplinary approach in which basic scientists and clinicians work closely together. This volume consists of nine chapters. Chapter 1 contains macro scopic and microscopic descriptions of coronary vascular anatomy, which is closely related to the functions of coronary circulation. In Chap. 2 two methods in current use to evaluate phasic coronary blood velocity waveforms are presented, i.e., the laser Doppler and ultrasound Doppler methods. Chapter 3 describes the mechanical properties of coronary circulation, a knowledge of which is indispens able for an understanding of coronary arterial and venous blood flow velocity waveforms in relation to cardiac contraction and relaxation."

The spinal cord has a characteristic structure and functions that are distinct from those of the brain. Its functions are tremendously important since it modulates the peripheral sensory inputs to the dorsal horn, and it gives rise to the ascending pathways transmitting peripheral afferent inputs to the brain, and conveys the descending pathways from the brain both to the lower motor neurons, the final common pathway, and to dorsal horn sensory neurons. In spite of these vital functions, the spinal cord constitutes only a small percent age of the mass of the human central nervous system and is located far from the skin surface, which has obstructed the recording of its electrical activity. Recently, however, important advances have been made in several recording techniques, including epidural recording or averaging methods, allowing both sensory and motor evoked spinal cord potentials in man to be recorded. This volume is based on the papers presented at the Fourth International Symposium on Spinal Cord Monitoring and Electrodiagnosis. Each of these international symposia has brought together many of the specialists involved in this research, with an important increase in the number of participants since the first symposium was held in Toyko in 1981. At the past symposia several attempts were made to standardize data, techniques, and clinical applications and to integrate the new findings into patient care."

Expanded knowledge about the pathophysiologic effects of severe in juries, advancements in the intensive care of victims of multiple injuries, and the treatment made possible by modem cardiovascular surgery make it appear sensible to combine the assessment and therapy of thoracic injuries into a synthesis of various branches of medicine. This monograph, therefore, is intended not only for the specialist in thoracic or cardiac surgery but also primarily for the person who is the first to be confronted by thoracic injuries, namely, the general surgeon or the traumatologist. It reflects my own personal experience as chief surgeon of an emer gency surgery ward of a university hospital and as head of an inten sive care unit for the severely wounded, which treats well over 100 patients with severe thoracic injuries annually, and is based on an analysis of these cases. My experience as a military surgeon in Vietnam was also taken into consideration. Many wounds in the area of the thorax can be successfully treated with simple, conservative procedures, though by "conservative" I do not mean to imply "inactive." An aggressive conservatism is need ed, which must pay attention to small details. In given cases, how ever, it requires the quick decision-making capability of the com petent surgeon. For this reason, considerable space is devoted to questions of evaluation and practical procedures."

It is essential to know all of the intricate lymph pathways when performing surgery for esophageal cancer in order to determine the extent of lymph node metastasis. Professor Sato has undertaken, at the request of the TNM Research Committee of the International Society for Diseases of the Esophagus, to map out and classify the lymph nodes of the mediastinum and neck. The beautiful artwork in the Color Atlas of Surgical Anatomy for Esophageal Cancer edited by Professor Sato gives an excellent understanding of the lymph node pathways and their importance in surgical treatment. Minute dissections which represent real life situations, not just the superficial pathways, show the precise location and topographical arrangement of the lymphatics. Full-color schematics are given with the actual dissection illustrations and photographs. The atlas clearly presents the classification of four significant pathways and their communication, the relationship of these pathways en route to the venous angles and the definition and assessment of the most critical nodes. Thoracic surgeons especially will benefit from the excellent illustrations of surgical techniques and the methods for recording the dissected lymph nodes which are presented by Professor Kakegawa. Leading experts fighting esophageal cancer with surgical treatment can use the classification in this outstanding atlas for many years to come as a standard for international comparison. The careful dissection of the lymph nodes may be the best way to improve survival rates after surgery for cancer of the thoracic esophagus.

During the past three decades, Vascular Surgery has emerged as a specialty within general surgery. Fellowships are now available to equip surgeons with specialized skills for managing various vascular problems. Nev ertheless, the vascular surgical emergency, one of the greatest challenges in surgical management, may occur suddenly and at a time and place remote from the highly qualified vascular surgeon or a specialized center where complex vascular treatment is routine. The initial evaluation and treatment must be undertaken by a general surgeon who determines the extent, sever ity, and urgency of the problem at hand, and hopefully will arrange appro priate transfer to a specialized center if the patient's condition permits. Urgent problems, on the other hand, demand immediate surgical interven tion by the general surgeon if any hope for salvage is to occur. It is in this set ting that this volume offered by Professor Staudacher may be of assistance to the general surgeon whose experience in this type of emergency may be limited. This concise, well illustrated volume should serve as a guide to manage the peripheral vascular emergency involving either the arte rial or venous system."

The papers presented in this book were held at the International Sym posium on "Prognosis of Coronary Heart Disease - Progression of Cor onary Arteriosclerosis" on October 22 and 23, 1982 in Bad Krozingen, FRG on the occasion of the 10th anniversary of the Rehabilitationszen trum Bad Krozingen. The symposium was sponsored and supported by the European So ciety of Cardiology and the Pharma Schwarz Co. The scientific com mittee was composed of F. Loogen (Dusseldorf), P. G. Hugenholtz (Rotterdam), and the editor of this book. To all of these and to my co-workers many thanks. Bad Krozingen, August 1983 H. Roskamm Table of Contents W. Steinbrunn and P. R.

This atlas offers a collection of EEG spectral analyses and their corresponding conventional recordings under anes thesio10gical procedures. The EEGs presented here were re corded on general surgical and gynecological patients during the last few years. Premedication, induction and maintenance of anesthesia, recovery the immediate postoperative period, and intensive care are covered. Techniques for operating the necessary equipment and artefacts relevant to the routine clinical use of EEG are briefly outlined. Typical examples of characteristic EEGs are presented at the beginning of each chapter, followed by illustrations of deviations from the norm showing the great variety of anesthesiologically induced changes of cerebral function. The description of each EEG course is assessed in relation to clinical parameters. Sometimes no satisfactory interpreta tion can be made, because many physiological and patho physiological causes of alterations in cerebral function are unknown. Time and again it proves impossible to estimate wether deviations from the norm have their origin in cerebral changes or are secondary to extracerebra1 disturbances. The atlas comprises a complete survey in itself, but it can also be seen as a supplement to the book The Electroenceph alogram in Anesthesia by I. Pich1mayr, U. Lips, and H. Kunkel (Springer, 1983), in which detailed lists of references are quoted that are omitted here."

Assisted Circulation 4 is an authoritative review of the progress which has been achieved in the last 5 years since the publication of "Assisted Circulation 3" in 1989. The present book highlights the work of well-known experts on indications for assisted circulation, cardiac support devices such as bridges, devices for transplantation, devices for chronic mechanical support, biological energy sources, cardiomyoplasty, extracorporeal membraneoxygenation and an overview of cardiac devices support with a specific emphasis on xenotransplantation. Assisted Circulation 4 is the latest product of an ongoing effort by the editors to keep readers regularly informed of recent developments in the field. Assisted Circulation is a standard technology in cardiac surgery and especially in cardiac transplantation.

Use of the implantable cardioverter/defibrillator is the most significant advance in the management of patients with life- botn threatening cardiac arrhythmias. This device represents an important practical as well as conceptual breakthrough in arrhythmia management. It places on firm footing use of non-pharmacologic tools for clinicians. The text, Implan- table Cardioverter/Defibrillator, represents contributions by the leading clinicians in this field from both sides of the Atlantic and is a welcome addition to the library of clinical electrophysiologists as well as cardiac surgeons. The editors have well collated the critical issues related to current use of device therapy in a meaningful and practical fashion. The text amply reminds us that we are in the early growth phases of a technology that promises to completely change our approach to the cure of patients with actual or potentially life-threatening ventricular dysrhythmias. It also reminds us that Dr. Mirwoski's dream continues to live and remains as a perpetual challenge to clinicians and engineers alike to bet- ter perfect and utilize device therapy for our patients. I com- mend the authors and editors for a superb and timely effort. San Francisco, CA, USA Melvin M. Scheinman, M. D. Preface 1teatment of patients with ventricular tachycardia and pre- vention of sudden arrhythmic death is one of the most challenging tasks of modem cardiology. 'len years ago anti- arrhythmic drug therapy was the medical tool used most fre- quently in the management of patients with life-threatening ventricular tachyarrhythmias.

Restenosis, the proliferation of smooth muscle cells (SMC) that line blood vessels, often follows angioplasty. Despite advances in cardiology, restenosis continues to affect up to 40% of the over 500,000 patients who undergo angioplasty each year. Applications of Antisense Therapies to Restenosis is the first volume to address the potential of using antisense therapies to inhibit the restenosis that occurs after percutaneous transluminal angioplasty and coronary stenting. The work critically examines the application of various antisense therapies for inhibiting restenosis.

"Rate Adaptive Cardiac Pacing" provides a comprehensive overview of this most advanced form of stimulating the heart by means of cardiac pacemakers that vary the pacing rate according to the needs of the patients. The heart rate is controlled by one or several sensors that detect various parameters such as respiration, blood temperature, oxygen saturation, intracardiac pressure, QT interval, stroke volume andbody activity. Besides describing the clinical and functional characteristics of these various sensors, the book also gives a clear understanding of hemodynamic aspects and in particular, all clinical issues of importance such as indications for rate adaptive pacing and selection of the appropriate patients for rate adaptive pacemakers, with many ECG samples. The book also covers new concepts in rate adaptive pacing such as single lead atrial synchronous pacing and the combination of various sensors, which are among the most recent developments in the field. With contributions from the most wellknown experts in the field from allover the world, this book is the first publication to cover all the hemodynamic, clinical and technical aspects of rate adaptive cardiac pacing.

A workshop was organised in order to achieve multi-discipli- nary review of the pathogenesis and management of acute failure, particularly as it occurs and is managed in intensive therapy units. The book deals with the realities and practicalities of this important area of acute medicine. Each chapter is followed by a discussion, so that a concen- sus view is obtained from an international body of experts.

Major epidemiologists from the UK, USA and Europe contribute to the first ever, much needed comprehensive review of the epidemiology of peripheral vascular disease in the lower limbs.

If a consecutive series of patients with lung cancer is followed up until the decision is made about therapy, it emerges that the role of surgery is quite small. Only a very limited proportion will ultimate ly qualify for rationally conceived surgical therapy; most patients are inoperable. In a series of 397 patients investigated at our hospi tal, 78% were inoperable on the basis of preoperative evaluation and a further 3% proved nonresectable at thoracotomy; therefore, only 19% were suitable for resection. On the other hand, surgery is still thought to offer the best, if not the only realistic chance of cure. The question "operable or not?" is therefore of vital importance for the individual patient. The answer to this crucial question must be based on valid guidelines for pa tient selection and preoperative evaluation, and it should be clearly defined what extent of resection is necessary in order to realize any curative intention. In 1972 a thorough analysis of the literature revealed that re section of bronchial carcinoma - although 40 years old - was being undertaken with very variable indications. There was hardly any systematic staging, and assessment of results was hampered by the fact that most communications in the literature were based on retrospective analysis.

La pathologie vasculaire a ete tres marquee par les progres biologiques de ces vingt demieres annees. Le systeme arteriel est main tenant considere comme un organe a part entiere. Modelee au cours de l'organogenese par les facteurs hemodynamiques, Ie paroi arterielle maintient une structure hautement organisee et des proprietes mecaniques qui dependent directement des conditions de pression et de debit. La monocouche endotheliale developpe 2 une surface de plusieurs centaines de m a l'interface sang-tissu; elle est a la fois un organe endocrine complexe synthetisant de nombreuses proteines qui participent a l'hemostase, une surface thromboresistante et hemocompatible, une barriere de permeabilite contr6lant les echanges sang-tissus. Les cellules musculaires lisses constituent un tissu multifonctionnel, contractile, assurant la synthese des composants structuraux responsables des proprietes mecaniques de la paroi arterielle, la transmission de la force contractile, et une etonnante activite reparatrice en reponse aux agressions. Tout ceci est soumis a un ensemble complexe de communications cellulaires qui font de l'endothelium un veritable systeme recepteur pour la paroi vasculaire. Parallelement, ou a la suite de ces progres, l'angeiologie s'est progressivement affirmee comme une specialite clinique. Debordant Ie cadre de la chirurgie vasculaire, elle integre les concepts physiopathologiques au diagnostic et au traitement des maladies arterielles. De cet effort d'integration est ne cet ouvrage, cherchant a concilier les connaissances fondamentales es plus recentes et la demarche clinique.

D. B. LONGMORE The concept ofthe meeting on which this book is based is unique. There has never be fore been a multi-disciplinary meeting based entirely on the concept of making a major branch of surgery safer. Hopefully, this meeting will be archetypal and will set a precedent for similar attempts in other disciplines as well as future efforts to make cardiac surgery safer. Cardiac surgery is still a rapidly growing discipline even after a quarter of a century of experience. Like any new area of science, or medicine, initially there is an exponential growth ofwork, publications, meetings, options of available equipment and all the ancillary and peripheral disciplines associated with it. The ideas of the handful of original surgical pioneers, some of whom have contributed to this book, formed the basis of a still rapidly growing young branch of surgery with a whole new medical discipline of total extracorporeal circulation involving biochemical and haemodynamic control of a patient.

In patients with coronary artery disease, surgical revascu- larization with arterial or venous bypass grafts not only relieves symptoms, but also prolongs life. The result of such interventions, however, is frequently impaired by graft dysfunction and occlusion. This monograph highlights the clinical importance of coronary artery bypass graft disease and, in particular, the use of modern diagnostic techniques to assess graft structure and function. The molecular and cellular mechanisms of coronary bypass graft disease are ex- tensively discussed with several chapters devoted to prophy- lactic medical therapy. The indication, technique and results of reinterventions with balloon angioplasty, reope- ration or transplantation in patients with graft failure are also reviewed.

Circulation through the deep femoral artery and its branches is critical to patients with aortoiliac and infrainguinal arteriosclerosis. It is, accordingly, essential that all physicians who are seriously interested in treating patients with lower extremity ischemia have a good working knowledge of this crucial artery's anatomy and func tion. It is equally essential that they be aware of arteriosclerotic disease patterns that involve this important artery, how these patterns can be Clccurately defined, and, most importantly, what therapeutic options are available and when they should be used. All this important information relating to the deep femoral artery and its surgical significance is included in Dr. Merlini's fine volume. Eighteen authors have contributed 11 well-edited and nicely illustrated chapters that provide all the facts that the com mitted vascular surgeon would ever want to know about the deep femoral artery and how it should be managed in patients with lower limb ischemia. Although some of the chapters overlap in some areas, this adds to the value of the book since the different authors are' all acknowledged experts and their varying perspectives. are beneficial to a reader seeking to formulate his own unbiased views.

Our common interest in surgery of the vertebral artery was born in 1976, when as residents in the same hospital, we attended an attempt by two senior surgeons to treat an aneurysm of the vertebral artery at the C 3 level. Long discussions had preceded this unsuccessful trial, to decide if surgery was indicated and to choose the surgical route. Finally a direct lateral approach was performed, but access was difficult and correct treatment was impossible, resulting in only partial reduction of the aneurysmal pouch. Following this experience, we decided to seek a regular and well defined approach for exposition of the vertebral artery. Review of the literature indicated some surgical attempts, but the descriptions did not give the impression of safety and reproducibility. No landmark on the described surgical route appeared sufficiently reliable. Henry's anatomical work (1917) gave the only accurate description on vertebral artery anatomy, and it became the basis for our work. When the same patient was referred again one year later, after a new stroke in the vertebro-basilar system, we had behind us repetitive experience on cadavers of an original approach to the distal vertebral artery.

Reconstructive microvascular surgery is now in its teens. At first many thought this new child was a whim and would fail to thrive. Some were un certain, others with vision either supported or became actively involved in this new area of surgical endeavour. Although initial interest was focused on the replantation of amputated parts, it has been the one stage free trans fer of living tissue to a distant site which has launched microsurgery into the surgical spotlight. From its humble beginnings we have witnessed a revolution in this branch of plastic surgery; many of the long established methods of recon struction have, like barricades, fallen before the advances made in this field. In its infancy there were relatively few procedures available. There was a tendency to make the patient's problem fit the operation, rather than the reverse, and this frequently led to an inferior result. The then known flaps, such as the groin flap and the deltopectoral flap, were employed. Unfortunately they were sites which posed many technical problems; namely those of vascular anomaly, a short pedicle and vessels of small cal ibre. Long operations were the norm, and vascular thrombosis was not un common. Hospital routine often was disrupted and there was a danger that these new techniques would fall into disrepute. Over the last decade this state of affairs has changed dramatically.
