[Transarterial embolization of dural carotid-cavernous fistulas].

OBJECTIVE: To explore the efficacy and strategy of transarterial embolization of dural carotid-cavernous fistulas. METHODS: The clinical data of 19 patients with dural carotid-cavernous fistulas treated by transarterial embolization, including clinical presentations and patterns of angioarchitecture were retrospectively analyzed. Follow-up was conducted for 7 months to 4 years. RESULTS: Clinical cure was achieved in 15 cases, significant improvement of symptoms in 3 cases, and failure in 1 case. Complete angiographic obliteration was documented in 12 patients (63%) right after the embolization. Residual shunting was left in 6 patients, and disappeared in 5 cases one month to half a year later by manual compression of the carotid artery. The patient on which transarterial embolization failed received embolization via the bilateral cavernous later, and clinical cure was achieved. Headache and vomiting were the most common symptoms after embolization. There was no permanent procedure-related morbidity. No recurrence was seen during the follow-up. CONCLUSION: Transarterial embolization is a safe, efficient and economical method for part of the cavernous sinus dural arteriovenous fistula patients.
