Neurosurgery of Arteriovenous Malformations and Fistulas

Arteriovenous malformations (AVM) and arteriovenous fistulas (AVF) differ from all other pathology affecting the central nervous system by their high-flow arteriovenous shunts. Permanent occlusion of these shunts is the essence and the challenge of therapy. Endovascular therapy and radiosurgery became accepted alternatives or adjuncts to surgery. In many instances the choice of the primary therapeutic modality is not clear and arguments can be found for several options. However, microsurgery, endovascular therapy and radiosurgery differ very much with regard to invasiveness, length of stay at the hospital but also residual risk after therapy. The emerging treatment concepts are the object of this book. The result is a unique structured presentation of AVM and AVF therapy.

Surgical Versus Conservative Treatment of Intracranial Arteriovenous Malformations

The main aim of this study is to define the clinical criteria which must be considered in order to come to an adequate decision whether a patient with intracranial arteriovenous malformation (AVM) should be operated upon or treated conservatively. A special method was used to reduce the effects of selection. This method made it possible to evaluate the therapeutic efficacy of conservative treatment versus surgery. The method implies that patients with equal combinations of variables (risk profiles) were compared in the two treatment lines. The variables building up the risk-profile pattern were chosen by analysing the decision process, as it was originally practiced by the surgeon who selected and treated the patients of this study. The risk profiles thus described relevant characteristics of the patient and his malformation. The variables were assigned numerical values accord ing to their prognostic value. Summation of the variables making up the risk profile then gives each risk profile a certain value. A low value symbolizes a bad prognosis and a high value a good prognosis in both treatment groups. There were many risk profiles with the same value in both groups and a comparison could be made over a large part of the risk-profile scale. This comparison showed that surgical treatment of A VM can always be justified, although the indications for surgery are less strong in patients with low risk profile values.

Arteriovenous Malformations in Functional Areas of the Brain

This book is the culmination of Dr Yamada's desire to promote the multi-disciplinary treatment of arteriovenous malformations (AVMs).

Arteriovenous Malformations in Functional Areas of the Brain

Despite the successful treatment of arteriovenous malformations (AVMs) in silent areas of the brain, only recently has the treatment of AVMs in functional areas moved within the scope of neurosurgical treatment. Dr Yamada’s guide, Arteriovenous Malformations in Functional Areas of the Brain meticulously explores the three clinically-accepted modes of AVM treatment (microsurgery, intravascular intervention, and radiosurgery) used individually or in conjunction with each other. This book is the culmination of Dr Yamada's desire to promote the multi-disciplinary treatment of arteriovenous malformations (AVMs). Introduced into this book is the surgical technique that Dr Yamada developed for complex AVMs, based on extensive analysis of the vascular anatomy, and meticulous planning and careful execution of the neccessary surgical steps. This monograph presents the work of an outstanding group of experts with individual expertise in the treatment of functional areas of AVMs and related pathophysiology. Contributions from neurosurgeons, neuroradiologists, radiosurgeons, neuroanaesthetists and neuropathologists combine to create a uniquely comprehensive and up to date account. This invaluable guide will become an important reference for all physicians who care for patients with cerebral arteriovenous malformations.

Arteriovenous Malformations

Arteriovenous malformations (AVM) represent some of the most complex and challenging pathologies for the modern physician to properly diagnose and manage. In this comprehensive guide, we detail the natural history, diagnosis and management of AVMs. The first eight chapters are dedicated to brain AVMs. Chapter 1 describes the natural history of brain AVMs, the understanding of which is crucial to deciphering the relative risks and benefits of AVM treatment. Chapter 2 focuses on the surgical treatment of brain AVMs. Chapters 3 and 4 delineate the role of endovascular embolization in the management of brain AVMs. Chapter 5 analyzes the outcomes of stereotactic radiosurgery for Spetzler-Martin grade III AVMs, which are the most heterogeneous subgroup of AVMs. Chapter 6 describes the role of stereotactic radiosurgery for large brain AVMs, which are notoriously difficult to safely and effectively treat by any means. Chapter 7 focuses on heavily charged particle beam radiosurgery for brain AVMs. Chapter 8 puts it all together by analyzing the relationships and interactions among the different treatment modalities for brain AVMs; when utilized synergistically, the morbidity of each therapy is minimized while its maximum benefit is extracted. The last two chapters are dedicated to Osler-Weber-Rendu syndrome, also known as hereditary hemorrhagic telangiectasia (HHT). Chapter 9 describes the genetics, pathogenesis, and management of HHT, with a focus on the diagnosis of pulmonary AVMs. Chapter 10 evaluates the role of endovascular intervention in the treatment of pulmonary AVMs.

Arteriovenous Malformations of the Brain and Spinal Cord

It is a common practice to describe the anatomy of the Arterio-venous malformations (AVM) with reference to adult anatomy.

Arteriovenous Malformations of the Brain and Spinal Cord

It is a common practice to describe the anatomy of the Arterio-venous malformations (AVM) with reference to adult anatomy. The arterial feeders and the venous sinuses into which the arterialised blood drains are easily identifiable. However the arterialised venous channels extending between the arteries and the dural sinuses are just described as "abnormal venous channels." These AVMs occur due to developmental anomalies in the embryos. It is possible to identify these vessels. These structures normally disappear during the course of development, as they become atritic due to diversion of blood away from them. In the presence of an AVM, these vessels persist because of the abnormal flow created by the fistula. This publication demonstrates the method of identification of these segmental vessels. It is possible to deduct the anatomy if the formations of these malformations are followed through the various stages of the development of the embryo. Knowledge of embryology is not necessary to identify the persistent segmental veins. Padget proposed that accidental defects between the primitive embryonic segmental pial vessels produce these Arterio-venous fistulae. This concept is developed to logically deduce the anatomy. It is not possible to demonstrate all the possible variations. The reader is provided with the methodology that will lead to the identification of the anatomy. The flow pattern in an AVM is unique. Two fluid systems of different pressures and flow are interconnected. There are numerous reports on the flow characteristics of these malformations based on the assumption that the equations for a flow in a linear tube are applicable. We have demonstrated by experimental evidence and computational fluid dynamic studies that the flow is extremely complex. The physics of linear flow is not applicable to AVM.
