Asymptomatic Carotid Artery Stenosis

This well-illustrated text reviews the current state of knowledge with regard to the various anatomic and physiologic methods available to identify asymptomatic patients who are at high risk to develop a future stroke. Asymptomatic Carotid Artery Stenosis is particularly targeted towards physicians involved in clinical decision making regarding rev

From patient selection and monitoring to follow-up care, Carotid Interventions is the first source to offer a practical how-to approach to carotid angioplasty and stenting-providing maneuvers and strategies for difficult situations, as well as step-by-step guidance on specific surgical procedures, equipment selection and instrumentation, protection

Carotid artery stenosis refers to atherosclerotic narrowing of the extracranial carotid arteries. It typically refers to the internal carotid arteries or the common and internal carotid arteries. A “clinically important” degree of stenosis is defined as the percentage of stenosis that corresponds to a substantially increased risk for stroke. However, because stroke risk depends on more than just the degree of stenosis, it is difficult to set a lower limit on the range that defines potential clinical importance. Asymptomatic patients have no significant neurologic symptoms referable to the carotid artery and have not experienced a cerebrovascular event (i.e., a stroke or transient ischemic attack). The main purpose of this report is to systematically evaluate the current evidence on whether screening asymptomatic adults for CAS reduces the risk for fatal or nonfatal ipsilateral stroke and the evidence on harms associated with screening and interventions for CAS. The scope and methods of this report differ from earlier USPSTF reviews on this topic by 1) using systematic methods for all key question, 2) addressing new key questions about the availability of valid, reliable risk stratification tools to distinguish a person's likelihood for asymptomatic CAS and to distinguish risk for ipsilateral stroke caused by CAS or for harms from surgery or intervention in persons with asymptomatic CAS (recommendations of some groups state that screening might be considered for persons with multiple risk factors), 3) adding carotid angioplasty and stenting (CAAS) to the included interventions, 4) adding a question about the incremental benefit of medical therapy for asymptomatic CAS, and 5) conducting quantitative synthesis for many outcomes.

Neurosonology is non-invasive, portable, and has excellent temporal resolution, making it a valuable and increasingly popular tool for the diagnosis and monitoring of neurological conditions when compared to other imaging techniques. This guide looks beyond the use of neurovascular ultrasound in stroke to encompass a wide range of other neurological diseases and emergencies. It offers a practical approach to the examination of patients, interpretation of ultrasound studies, and the application of neurosonology to the development of management and treatment strategies. Each chapter incorporates a thorough and clear procedural methodology alongside scanning tips for trainees; this step-by-step approach is further enhanced by example images and focused diagnostic questions. Authored and edited by international experts, this practical manual of neurosonology is an invaluable resource for neurologists, neurosurgeons, intensivists, radiologists, and ultrasonographers.

This book provides easily accessible technique specific information on interventional radiology (IR) procedures at a basic level for medical students and junior doctors. It covers subject topics in both vascular and non-vascular interventional radiology appropriate for a non-specialist audience. Case based contents help to introduce IR techniques and demonstrate the role of minimally invasive therapy in the overall clinical management. Pre and post-procedural patient assessments are also included in the chapters to enhance patient safety and early detection of complications. Interventional Radiology treatments now play a major role in many disease processes and continues to grow with new procedures added to the armamentarium of the interventional radiologist, almost on a yearly basis. Interventional radiology because of its pivotal role in medical care, requires its own teaching curriculum. Recognising this, the Cardiovascular and Interventional Radiology Society of Europe (CIRSE) devised an undergraduate curriculum in IR, specifically designed for teaching medical students. This book will be primarily of benefit to medical students. In addition, it will also be of help to non-radiology junior hospital doctors and general practitioners.

Written by internationally recognized experts in interventional cardiology, this comprehensive clinical reference on carotid artery stenting provides illustrated, step-by-step descriptions of techniques and details on indications, contraindications, patient selection, complications, technology, and clinical trials. The first section reviews clinical results and experience, including the CAVATAS trial findings on stroke prevention. The second section describes stenting techniques and includes information from major trials on design and application of devices. The third section presents guidelines and current regulations on establishing a carotid stenting program. The book concludes with a preview of future directions.
