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.

The first book-length reference to thoroughly describe diagnostic and therapeutic advances in the development of vascular radiology over the last decade The last ten years has seen vascular imaging of the central nervous system (CNS) evolve from fairly crude, invasive procedures to more advanced imaging methods that are safer, faster, and more precise—with computed tomographic (CT) and magnetic resonance (MR) imaging methods playing a special role in these advances. Vascular Imaging of the Central Nervous System is the first full-length reference text that shows radiologists—especially neuroradiologists—how to optimize the use of the many techniques available in order to increase the sensitivity and specificity of vascular imaging, thereby improving the diagnosis and treatment of individual patients. Each chapter is formatted carefully and divided into two essential parts: The first part describes the physical principles underlying each imaging technique, along potential associated artifacts and pitfalls; the second part addresses clinical applications and novel applications of each method. With a strong focus on the clinical application of each modality or technique in CNS radiology, this book provides in-depth chapter coverage of: • Ultrasound Vascular Imaging (UVI) • Computed Tomography Angiography (CTA) • Magnetic Resonance Vascular imaging (MRV) • Digital subtraction angiography (DSA) • Brain perfusion techniques: CT and MRI • Plaque imaging • Intravascular imaging • Pediatric vascular imaging Along with numerous illustrations and case studies, Vascular Imaging of the Central Nervous System: Physical Principles, Clinical Applications, and Emerging Techniques is an important book for those faced with choosing from the wide range of choices available for clinical practice.

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.

Neuromonitoring is the tool of trade in intensive care, and should incorporate cutting edge technology with patience, repeated clinical observation, careful identification of neuroworsening. The aim of the book is to be of practical use, and to assist the clinical practice of the busy physician. The clinical examination belongs to the introductory section of the book, and an abundance of technology, with specific emphasis on the importance of intracranial pressure, comes in the following parts. Since the patient with an injured brain can have chances only if other organs and systems (as the lungs, and the acid-base equilibrium etc.) are preserved, a section of the book covers the interactions between the affected brain and other organs. The way the brain reacts to different insults has common aspects, as inflammatory responses, edema etc., but also specific features. Sections five to nine summarize the most relevant pathologies, from ischemic to hemorrhagic lesions, trauma, tumors etc. and also mentions new‑comers, as the specific problems related to the expanding field of neuroradiological interventions. Finally, neurointensive care does not exist without knowledgeable nurses. The intracranial pressure measurement starts (or unfortunately ends) with a catheter well maintained, and that becomes vital when the drainage of hydrocephalus is concerned. Dealing with patients with severe brain damage has plenty of ethical implications, up to the problems related to brain death and organ donation. This book is published in two volumes.
