Book excerpt: Cerebral veins contain about 70% of the total cerebral blood volume, but cerebral venous thrombosis (CVT) occurs about a thousand times less often than arterial stroke. CVT affects mostly young adults and children, and in about one quarter of cases the cause remains unknown. Written by international experts, this publication is dealing with epidemiology, risk factors, coagulation disorders, clinical presentation - especially focusing on headache, current neuroradiological treatment, complications and long-term prognosis of CVT. The book covers the full spectrum of CVT pathogenesis and offers a new and effective approach to improve earlier diagnosis, recognize new risk factors and to identify the most severe manifestations, which require more aggressive treatments. Neurologists, interventional neuroradiologists, neurosurgeons, and all physicians who are involved in the care of patients with CVT will welcome this publication as a useful and up-to-date clinical guide.
