(Medicine is dependent upon changing concepts for progress...)
Medicine is dependent upon changing concepts for progress in treatment of patient problems. Perhaps nowhere in medicine is conceptual change so obvious as in study of the cerebral vasculature and its effects upon brain physiology. The ancients were particularly confused about the brain, and although the Egyptians described pulsations of the brain during life, they were ignorant of brain circulation. This was because they did not differentiate between tendons, nerves, and blood vessels. Similarly, though Pythagoras characterized the brain as an organ of reasoning, this concept was denied by no less a figure than Aristotle 200 years later. Even the anatomical distribution of the cerebral blood vessels has been subject to changing concepts. For example, Galen felt that the rete mirable, seen in lower animals such as the dog and cat, was present in man. This concept stood for a thousand years, until Vesalius described the course of the internal carotid artery and changed forever Galen's erroneous concept. Even Vesalius himself was in error. The most cursory study of his drawings will show a large communication between the internal carotid artery and the tranverse sinus, a concept that demanded change. Changing concepts and ideas are a part of our time, and many of these are the focus of the chapters in this volume. Eastcott, who was present at the birth of carotid surgery, begins a discussion of these changing concepts in his contribution on the beginning of this surgical art. Further examples of changing ideas with regard to the genesis of carotid artery plaques and the mechanisms of production of transient ischemic attacks are detailed in the contributions of Zarins, Giddens, and Glagov on atherosclerotic plaque distribution, and of Salzman on the role of platelet-vessel interaction in cerebrovascular disease. The increasing importance of intraplaque hemorrhage in the genesis of neurologic deficit is emphasized by Lusby, Ferrell, and Wylie in their chapters.
