Transvenous embolization has become the treatment of choice for such lesions We evaluated Onxy for patients with cavernous dural arteriovenous fistulae (CDAVFs) who underwent transvenous embolization via different transvenous approaches. Case records of six patients with symptomatic CDAVFs, treated between October 2006 and November 2007 were reviewed. A total of seven transvenous procedures were performed in the six patients with CDAVFs. All the patients with CDAVFs of the cavernous sinus were symptom free following embolization. The approach via the internal jugular vein and the inferior petrosal sinus was possible in four of the six patients, with complete occlusion of the fistula. In the remaining two patients, the approach was via the facial vein. Transient bradyarrythmia without morbidity was the only complication in two patients.
