Collateral Circulation by Wolfgang Schaper,Jutta Schaper Pdf

Collateral blood vessels develop by growth of pre or newly formed structures in almost all vascular provinces as a consequence of progressing stenosis of the main artery. These alternative routes of blood supply are potentially able to alter the course of vascular disease. Collateral development is a time consuming process, and arterial stenosis and occlusion often progress faster than growth of the alternative routes. The authors' ultimate goal is to provide a better understanding of collateral growth in order to pave the way for improving the conditions for these potentially selfhealing processes. These were programmed by nature but have not been perfected, probably because defenses against arterial disease had not been put under the pressure of natural selection.

Collateral Circulation of the Heart by Christian Seiler Pdf

The sober explanation for this book is a call by the Springer-Verlag, London, to edit a publication on ‘The functional relevance of the collateral circulation’ of the heart. Alternatively, it could be ‘sold’ as the result of my intention to reduce entropy of 18 years of scientific work on the topic of the coronary circulation, which was itself meant to diminish the amount of ‘useless’ energy. Such a process of reducing disarray in a system with the aim of grasping it better is related to simplification, which carries the risk of introducing error. This can be exemplified by the historic view of angina pectoris, which used to be simplified as being always fatal, thus obscuring for nearly two centuries the view of a ‘self-healing’ mechanism such as the collateral circulation of the heart. It would be na? ̈ve, to assume the present work to be free of erroneous oversimplification, because the very nature of scientific work is related to generating (simple) hypotheses with their subsequent falsification. In that context and bluntly, my primary interest in the field of the collateral circulation was not initiated with a vision of eradicating the consequences of coronary artery disease (CAD) by promoting the growth of natural bypasses. The time for such sizeable ideas had passed in the 1970s with the start of the work by Wolfgang Schaper.

The Cerebral Circulation by Marilyn J. Cipolla Pdf

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.

Regulation of Coronary Blood Flow by Michitoshi Inoue,Masatsugu Hori,Shoichi Imai,Robert M. Berne Pdf

Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

Portal Hypertension by Kunio Okuda,Jean-Pierre Benhamou Pdf

Portal hypertension is the abnormal pathophysiologic state that develops in liver cirrhosis and certain other disorders with characteristic clinical and hemodynamic features. There has been great progress in our under standing and management of portal hypertension, particularly in the diagnostic and therapeutic approaches. The so-called Banti's syndrome, a disorder whose existence had long been questioned, is now a well-defined portal hypertensive disease. The recently introduced Doppler ftowmetry is currently yielding new information on portal hemodynamics. Endoscopic sclerotherapy and beta-blockers have come to be widely used in the man agement and prevention of variceal bleeding. In spite of all these advances, a number of unsolved questions remain, such as whether sclerotherapy, pharmacotherapy or surgery is warranted for prevention of bleeding, which is more effective as an elective treatment, the surgical or endoscopic approach, and whether surgical portacaval shunt should be totally replaced by selective shunt operations. These new developments and problems are clearly and comprehensively described and discussed by the foremost authorities in 44 chapters, which are divided into five sections: 1) Patho physiology, 2) Hemodynamic Investigations, 3) Imaging Investigations, 4) Clinical and Pathological Features, and 5) Esophageal and Gastrointestinal Bleeding. The primary goal of this monograph, to provide a framework of patho physiology of portal hypertension with authoritative descriptions of the clinical and laboratory manifestations of various portal hypertensive dis orders, has clearly been achieved by these excellent contributions.

Physiological Assessment of Coronary Stenoses and the Microcirculation by Javier Escaned,Justin Davies Pdf

​Since the introduction of coronary angiography, a key technique in understanding coronary artery disease, a number of paradigms regarding its study and interpretation have taken place. Following an emphasis on improved angiographic and subsequent intracoronary imaging techniques, functional assessment of coronary circulation has demonstrated to have major implications for diagnosis and treatment of coronary artery disease. Fractional flow reserve, a pressure derived index of stenosis severity, constitutes the best example of the current importance of physiological assessment in clinical practice. However, the acceptance of FFR by cardiologists contrasts with important voids in knowledge on the basic principles of coronary physiology and of other available techniques that, as an alternative to FFR, allow a more comprehensive assessment of coronary circulation. This is particularly noticeable in the assessment of microcirculation, an unavoidable compartment of coronary circulation that is frequently affected in acute coronary syndromes of in the presence of cardiovascular risk factors or non-coronary heart disease. A deeper understanding of the relationship between epicardial vessel and microcirculatory involvement has started with the advent of newer imaging techniques like invasive optical coherence tomography, and non-invasive CT and NMR techniques. This book aims to be an indispensable tool for clinicians and researches in the field of coronary artery disease. It provides a balanced, comprehensive review of anatomy, physiology and available techniques, discusses both the diagnosis of epicardial vessel and microcirculatory disease, the impact of different diseases at different levels of coronary circulation, and the best way to address a separate or combined assessment of different levels of coronary circulation. ​
