Book Description
The ischemic penumbra was initially defined by Symon, Lassen and colleagues in the 1970s as an area of brain tissue with inadequate blood flow to maintain electric activity of neurons but adequate blood flow to preserve the function of the ion channels. This area of tissue, receiving enough blood to survive but not enough to function, often surrounds or abuts the irreversibly damaged core in ischemic stroke. It was shown that if blood flow could be restored to this area of marginal perfusion, the tissue could survive and function again, and growth of the core could be prevented. Based on seminal PET studies, penumbra or "penumbral tissue" eventually took on a subtly different meaning - the area of brain that is destined to progress to infarct unless blood flow is restored within a particular time window. The penumbra thus became the target for all acute stroke interventions - to preserve viability of the tissue and restore function. New imaging techniques, including diffusion and perfusion MRI and CT perfusion, were developed to rapidly identify individuals with penumbra, who were thought to be the best candidates for aggressive interventions to restore blood flow, particularly beyond the licensed time-window for IV thrombolysis. However, most clinical trials have failed to establish the usefulness of identifying candidates for treatment in this way using pre-specified protocols and primary endpoints. These trials have used different and sometimes unvalidated thresholds of hypoperfusion as well as irreversible infarct and various definitions of significant penumbra (or mismatch between irreversible infarct and hypoperfused, but salvageable tissue), and reanalysis of their data using more refined image processing showed post-hoc positivity. They have also evaluated outcome in a variety of ways, with few studies measuring the direct effect of restoring blood flow on the function of the penumbral tissue. Therefore, important remaining questions include how to define, characterize, and image the penumbra in acute stroke to achieve the greatest reliability and validity for what we want to measure, and whether this concept, so defined, provides an optimal target for stroke therapy using state-of-the-art trial design.

Book Description
This updated second edition of Acute Ischemic Stroke: Imaging and Intervention provides a comprehensive account of the state of the art in the diagnosis and treatment of acute ischemic stroke. The basic format of the first edition has been retained, with sections on fundamentals such as pathophysiology and causes, imaging techniques and interventions. However, each chapter has been revised to reflect the important recent progress in advanced neuroimaging and the use of interventional tools. In addition, a new chapter is included on the classification instruments for ischemic stroke and their use in predicting outcomes and therapeutic triage. All of the authors are internationally recognized experts and members of the interdisciplinary stroke team at the Massachusetts General Hospital and Harvard Medical School. The text is supported by numerous informative illustrations, and ease of reference is ensured through the inclusion of suitable tables. This book will serve as a unique source of up-to-date information for neurologists, emergency physicians, radiologists and other health care providers who care for the patient with acute ischemic stroke.

Book Description
Highlighting concepts of brain ischemia, this book looks at the molecular mechanisms of its development leading to brain tissue changes and describes strategies of neuroprotective therapy. Coverage includes cellular reactions in response to acute focal brain ischemia, microglial activation and local inflammation in focal brain ischemia, programmed cell death, primary and secondary neuroprotection, gangliosides, and modern therapeutic approaches to acute focal brain ischemia. The authors are neurologists affiliated with the Russian State Medical University. Annotation (c)2003 Book News, Inc., Portland, OR (booknews.com).

Book Description
Toole's Cerebrovascular Disorders was the first modern book devoted to care of the stroke, originally published more than 40 years ago. This is a completely revised and updated sixth edition of the highly respected standard for stroke diagnosis and treatment. Dr James Toole has stayed on as a consultant for the text, and Drs E. Steve Roach, Kerstin Bettermann, and Jose Biller have reworked Dr Toole's book to include chapters on genetics, pregnancy-related stroke, and acute treatments. The practical focus of the book has not changed, retaining its emphasis on bedside diagnosis and treatment. Easily accessible both for stroke specialists and residents, the sixth edition has been modernized to keep pace with the rapid expansion of knowledge in stroke care and includes evidence-based recommendations, the latest technology and imaging, and risk factors. The text is supplemented with more than 200 images, many in color.

Book Description
A practical textbook, based on a problem-oriented workflow, that will improve patients' likelihood of full recovery from stroke and prevent future strokes from occurring Stroke is the leading cause of adult disability and is in the top five causes of death globally. Warlow's Stroke: Practical Management, 4th Edition takes a problem-oriented approach and addresses the questions posed by a stroke patient in the order they are likely to present in clinical practice, for instance, 'Is it a stroke?', 'What sort of stroke?', 'What caused it?', and 'What can be done about it?'. Beginning with chapters phrased as questions, the book walks the reader through a standard clinical workflow, exploring the practical skills and assessment required at each stage of patient management. Early chapters cover: locating the vascular lesion, identifying the involved arterial territory, the role imaging should play, and the application thereof. Subsequent chapters look at what causes a transient or persistent ischemic event, an intracerebral hemorrhage and a subarachnoid hemorrhage. Unusual causes of ischemic stroke and transient ischemic attack are also covered. The book then presents a practical approach to the management of stroke and transient ischemic attack; offers specific treatments for acute ischemic stroke and aneurysmal subarachnoid hemorrhage; provides ways for professionals to prevent first or recurrent stroke; and more. Final chapters of the book discuss rehabilitation after stroke, how patients and carers can be supported in the short term and long term, prevention of recurrent stroke, and the organization of stroke services. Warlow's Stroke: Practical Management, 4th Edition Follows clinical workflow for stroke analysis Features evidence-based approach throughout Offers practical application aimed at improving patient outcomes Written and edited by internationally renowned experts in the field An essential resource for all practitioners involved in the care of patients who suffer from cerebrovascular disease, but particularly suitable for neurologists, residents, geriatricians, stroke physicians, radiologists and primary care physicians.
