What is arterial dissection? What is Moyamoya angiopathy? What is the state of art of AVM treatment? Readers will find answers to these questions in this book. But they will also be informed about the state of the art treatment in the daily stroke therapy.

The cerebello-pontine angle has always posed a challenge to the neurosurgeon, the otoneurosurgeon, and the neuroradiologist. Angle masses which are very small and difficult to detect frequently produce symptoms, but may remain silent while growing to exceptional size. The neuroradiologist must have firm knowl­ edge of the clinical manifestations of the diverse angle lesions in order to tailor his studies to the patients'' needs. The majority of angle lesions are benign; thus successful surgery has the potential for complete cure. Angle lesions typically arise in conjunction with vital neurovascular structures, and often displace these away from their expected positions. Large lesions may attenuate the vestibulocochlear and facial nerves and thin them over their dome. Since the nerves often remain functional, the surgeon then faces the need to separate the tumor from the contiguous nerve, with preservation of neurological function. Depending on the exact location and extension of the lesion, resection may best be attempted via otologic or neurosurgical approaches. The neuroradiologist must determine - precisely -the presence, site, size, and extension( s) of the lesion and the displacement of vital neurovascular structures as a guide to selecting the line of surgical attack. Since the arteries, veins, and nerves that traverse the angle are fine structures, the neuroradiologist must perform studies of the highest quality to do his job effectively.

The methods of interventional neuroradiology represent a distinct and difficult branch with­ in the new field of interventional radiology. The editor of this volume, Anton Valavanis, is a pioneer in this area, and one of the outstanding neuroradiologists in the world. Furthermore, he has brought together the foremost scientists and clinical neuroradiologists in the field to present the individual chapters. The book gives an overview ofthe state of the art in interventional neuroradiology. Each of the 12 chapters is devoted to a disease which can be treated by interventional neuroradio­ logical techniques. Pertinent information is provided on anatomical detail, technical back­ ground, and clinical aspects; in each case a detailed description of the indications, techniques, and possible complications of interventional neuroradiology is provided. Due consideration is given to the endovascular and nonvascular applications of the techniques. This book is the first comprehensive update of interventional neuroradiology and will acquaint the reader with well-established facts, recent advances, and future perspectives within this new discipline. It will be of special value to those working in neuroradiology but will also prove very helpful for neurosurgeons, neurologists, and ophthalmologists, as well as all physicians and researchers in the clinical neurosciences. We hope that the book will meet with the reception and success that it undoubtedly merits.
