Department of Otorhinolaryngology, Head and Neck Surgery; Saarland University Medical Center, Homburg/Saar, Germany.

Purpose: Cavernous sinus dural arterio-venous malformations (dAVF) represent a pathologic connection between branches of the internal and/or external carotid artery and the cavernous sinus. Standard endovascular approaches for dAVF treatment are transvenous embolization through the inferior petrosal sinus or the facial vein and transarterial embolization. These approaches are not always successful or feasible, and alternative techniques are required. Read More
