The microcirculation of the gastrointestinal tract is under the control of both myogenic and metabolic regulatory systems. The myogenic mechanism contributes to basal vascular tone and the regulation of transmural pressure, while the metabolic mechanism is responsible for maintaining an appropriate balance between O2 demand and O2 delivery. In the postprandial state, hydrolytic products of food digestion elicit a hyperemia, which serves to meet the increased O2 demand of nutrient assimilation. Metabolically linked factors (e.g., tissue pO2, adenosine) are primarily responsible for this functional hyperemia. The fenestrated capillaries of the gastrointestinal mucosa are relatively permeable to small hydrolytic products of food digestion (e.g., glucose), yet restrict the transcapillary movement of larger molecules (e.g., albumin). This allows for the absorption of hydrolytic products of food digestion without compromising the oncotic pressure gradient governing transcapillary fluid movement and edema formation. The gastrointestinal microcirculation is also an important component of the mucosal defense system whose function is to prevent (and rapidly repair) inadvertent epithelial injury by potentially noxious constituents of chyme. Two pathological conditions in which the gastrointestinal circulation plays an important role are ischemia/reperfusion and chronic portal hypertension. Ischemia/reperfusion results in mucosal edema and disruption of the epithelium due, in part, to an inflammatory response (e.g., increase in capillary permeability to macromolecules and neutrophil infiltration). Chronic portal hypertension results in an increase in gastrointestinal blood flow due to an imbalance in vasodilator and vasoconstrictor influences on the microcirculation.

This book provides a comprehensive account on individually rare, but collectively frequent diseases of the liver. In the first part, conditions such as hepatic vascular malformations, ischemic cholangiopathy, hepatic artery occlusion, sinusoidal conditions and Budd-Chiari syndrome are discussed among others. The second part examines the causes of vascular liver disease namely, coagulation disorders, neoplasm disorders, non-malignant blood disorders, systemic diseases and toxins, among others. The unique expertise of the authors, who are all members of the Vascular Liver Disease Disorders Group, an independent network of researchers with a common interest in Vascular Liver Diseases, are merged for an optimal pragmatic and individualized approach. This book is of interest to a broad range of experts, such as hepatologists, internists, radiologists and angiologists.

This practical, comprehensive anatomy book arms FRCA candidates with detailed, robust anatomical knowledge via a question-based approach.
This book is an up-to-date, technically detailed yet easy-to-read reference book on current clinical applications of MDCT in small animals. It has been designed to serve as the reference book for all MDCT-users, such as veterinary radiologists, imaging technicians, oncologists, surgeons, and non-radiologist clinicians. Individual chapters on novel clinically important topics include applications in endocrinology, oncology, trauma, and cardiovascular CT, as well as sections on organ-specific pathologies and their CT characteristics. The book will also cover main domains of CT, such as thorax and the trauma imaging. Anatomy, clinical aspects, pathology, and CT signs are integrated to provide the reader with the basis for interpretation of MDCT findings. Many excellent 2D multiplanar and 3D figures illustrating typical CT findings of various conditions will serve as a clinical reference for the reader.
This open access book deals with imaging of the abdomen and pelvis, an area that has seen considerable advances over the past several years, driven by clinical as well as technological developments. The respective chapters, written by internationally respected experts in their fields, focus on imaging diagnosis and interventional therapies in abdominal and pelvic disease; they cover all relevant imaging modalities, including magnetic resonance imaging, computed tomography, and positron emission tomography. As such, the book offers a comprehensive review of the state of the art in imaging of the abdomen and pelvis. It will be of interest to general radiologists, radiology residents, interventional radiologists, and clinicians from other specialties who want to update their knowledge in this area.
This book thoroughly covers various diseases induced by portal hypertension, and introduces novel information for the treatment of patients. Individual chapters address the pathophysiology, diagnosis and treatment options available for the complications induced by portal hypertension. The book fosters practical understanding and provides more evidence-based treatment options in order to improve physicians’ ability to select optimal treatment methods for their patients. Further, it offers readers the latest information concerning developments of the disease such as esophaogastric varices, ectopic varices, portal thrombosis, refractory ascites and hepatic encephalopathy. Clinical Science of Portal Hypertensions is an indispensible resource for both beginning and experienced gastroenterological physicians, endoscopists, liver physicians, radiologists, gastroenterological surgeons, liver surgeons, etc. who treat patients with portal hypertension on a clinical or research basis.
