Objective To investigate the efficacy of transvenous embolization in the management of cavernous dural arteriovenous fistulas. Methods Nine patients with cavernous dural arteriovenous fistulas diagnosed by digital subtraction angiography (DSA) were treated by transvenous embolization. Results Eight of the 9 patients were cured and 1 patient showed symptomatic improvement after the operations. No deterioration or death occurred in these cases. Follow-up of the patients for 2 to 96 months found no cases of relapse or exacerbation. Conclusion Transvenous embolization is effective and safe in the management of cerebral dural arteriovenous fistulas.
