Abstract
Background:Ethmoidal dural arteriovenous fistulas (eDAVFs) are usually approached via a pterional or a frontal craniotomy. A more direct route to the fistula is possible through a purely transfrontal sinus approach. The aim of this report is to illustrate the interest of transsinus frontal approach for eDAVFs.Case Description:The transfrontal sinus approach is described and illustrated in a case of an ethmoidal arteriovenous fistula. This approach is the most direct when treating an eDAVF surgically, allowing preserving neural structures with minimal to no brain manipulation.Conclusion:For eDAVFs, the purely transfrontal sinus approach is highly worth considering in cases of large frontal sinuses.
Highlights
Ethmoidal dural arteriovenous fistulas are usually approached via a pterional or a frontal craniotomy
Ethmoidal dural arteriovenous fistulas are known for their grim natural history leading to a high risk of hemorrhage.[5,22,25]
The transfrontal sinus approach offers a more direct route reducing the distance between the site of entrance and the lesion itself, obviating the need for brain manipulation
