Abstract
AbstractTentorial dural arteriovenous fistulas (TDAVFs) located and occur in the (reflected) double dural layer of the tentorium and its attachments. The vast majority have leptomeningeal venous drainage and tend to cause intracranial hemorrhage or progressive neurological deficits. These lesions are often more challenging to treat than DAVFs at other locations and may require multiple treatment sessions and/or combined approaches. Because of their rarity, the number of reports describing TDAVFs and their endovascular management is limited. The introduction of the nonadhesive liquid agent ethylene-vinyl alcohol represents a paradigm shift regarding the endovascular treatment for TDAVFs. Endovascular treatment is a safe and effective therapy for TDAVFs. Transarterial embolization could be used as a primary therapeutic option for most TDAVFs. When a transarterial approach is not possible or does not result in total lesion occlusion, transvenous or combined approaches can be performed, leading to high angiographic occlusion rates.KeywordsCerebral angiographyDural arteriovenous fistulaEmbolizationArteriovenous fistulaTentorium cerebelli
