Shunt

Shunt: a mechanism which bypasses/diverts accumulations of fluid to an absorbing or excreting system. Though the shunt operation is the most common neurosurgical procedure performed, it has a high failure rate (one year averaged a 30% failure rate). A problem is the lack of understanding and lack of knowledge, by neurosurgeons, of basic fluid dynamics and internal workings of the shunts themselves. They simply use "what they were trained on" without the benefit of an objective guide to the best shunts and why they are superior to others. As the author states, their only other source of information comes from biased manufacturer's representatives. The Shunt Book fills a void in the literature by presenting basic information on types of shunts and their functions, thus allowing neurosurgeons to rationally select shunt equipment and understand their mechanical effects. This inexpensive and easily accessible handbook offers chapters on fluid dynamics, internal mechanisms of shunts, types of shunts available, alternative devices and how to measure shunt effectiveness. This volume discusses How shunts work, How shunts fail, Alternatives to shunts, and Measuring implanted shunt performance.

In the last ten years the pediatric neurosurgeon has witnessed a real revolution in the diagnosis and treatment of pediatric hydrocephalus, the most frequently encountered condition in everyday clinical practice. The evolution of MRI and the advent of neuroendoscopic surgery have resuscitated the interest in the classification, etiology and pathophysiology of hydrocephalus. The book offers an updated overview on the recent progress in this field, and a new approach to hydrocephalus: the reader will find in it a modern and new presentation of an old disease, where genetics, endoscopy, cost-effectiveness analyses and many other aspects of the various therapies are extensively discussed. The volume will be useful not only for neurosurgeons, but for all specialists interested in the various aspects of hydrocephalus: pediatricians, radiologists, endocrinologists, pathologists and geneticists.

The gold standard text-reference Diagnostic Nuclear Medicine is now in its Fourth Edition--with a sharp clinical focus, a streamlined new single-volume format, and a very attractive price. Written by the top authorities in the specialty, this brand-new edition offers encyclopedic coverage of clinically relevant developments in nuclear medicine--including instrumentation, radiopharmaceuticals, and applications. Readers will find the latest on PET, molecular imaging, SPECT myocardial perfusion imaging, monoclonal antibody therapy, and the use of functional imaging studies in oncology. This edition has been trimmed from two volumes to one, so that readers can find exactly what they need quickly, without cross-checking between volumes.

Liver resection stands as the gold-standard therapeutic approach for selected cases of hepatocellular carcinoma (HCC). The extent of resectable parenchyma hinges upon the underlying liver function and its regenerative potential. Consequently, cirrhosis may impede access to potentially curative interventions for HCC arising within this context. Cirrhotic patients undergoing liver resection face heightened susceptibility to post-hepatectomy liver failure (PHLF). The clinical profile of PHLF bears a resemblance to a well-documented syndrome within the liver transplant (LT) domain: Small-for-size syndrome (SFSS), a form of graft failure observed in the postoperative phase following LT with undersized or partial organs. Management of SFSS targets mitigating the overflow syndrome, achievable through diverse portal diversion techniques. Portal vein flow diversion encompasses procedures redirecting a variable proportion of portal vein flow towards systemic circulation. Consequently, derivative procedures aim to directly alleviate portal hypertension. Side-to-side portocaval shunts emerge as the most straightforward and efficacious means of decompressing the portal system. Furthermore, they afford flow calibration to diminish the incidence and severity of steal syndrome and hepatic encephalopathy, without compromising efficacy or hepatic function. Translating insights gleaned from LT complexities involving SFSS to liver resection, strategies involving portal flow diversion warrant consideration in efforts to forestall PHLF. This approach aims to extend the frontiers of liver surgery, broadening access to hepatectomy with curative intent, either as a standalone intervention or as part of a comprehensive treatment regimen where LT serves as a secondary option.

Written and edited by leading international authorities in the field, this book provides an in-depth review of knowledge of complications of CSF shunting, with emphasis on prevention, identification, and management. It covers the full range of shunt-related complications and the various associated adverse consequences that remain common despite significant improvements in imaging techniques and therapeutic methods. The chapters are organized into two parts: complications of extrathecal CSF shunt devices and complications of endoscopy. In addition to providing clinicians and investigators with the most pertinent current evidence, the book looks forward to future areas of hydrocephalus research and to innovative therapeutic philosophies. This comprehensive reference book will be an ideal source for neurosurgeons seeking both basic and more sophisticated information and procedures relating to the complications associated with CSF shunting.
