Abstract
Clinical, radioanatomical, and therapeutic aspects of dural arteriovenous malformations in the region of the transverse sinsu are discussed on the basis of seven personal observations and the analysis of 72 reported cases. Common symptoms are headache and troublesome tinnitus aurium. More serious neurological deficiencies may occur as a result of distrubance in cerebral hemodynamics. A complete neuroradiological investigation is essential for adequate treatment. Most frequent arterial feeders are the occipital, tentorial, and middle meningeal arteries. Ligation of the occipital artery is not sufficient in most cases. Operative isolation of the transverse sinus by craniotomy and dural section is considered by far the most successful treatment and should be performed whenever ligations fail or are not indicated.
