Diffuse dural enhancement in cavernous sinus dural arteriovenous fistula

We describe unusually extensive contrast enhancement of the dura mater on MRI in a case of dural arteriovenous fistula of the cavernous sinus.     

Percutaneous transvenous packing of cavernous sinus with Onyx for cavernous dural arteriovenous fistula

Objective

The aim of this study is to describe the technique and results of the transvenous approach for occlusion of cavernous dural arteriovenous fistulas (DAVFs) with Onyx.

Methods

Eleven patients presenting with clinically symptomatic DAVFs, were treated between August 2005 and February 2007 at Beijing Tiantan Hospital. We were able to navigate small hydrophilic catheters and microguidwires through the facial vein or inferior petrosal sinus (IPS) into the ipsilateral cavernous sinus. After reaching the fistula site the cavernous sinus was packed with Onyx or combining with detachable platinum coils.

Results

We were able to reach the fistula site and to achieve a good packing of Onyx or combining with coils within the arteriovenous shunting zone in 10 patients. The final angiogram showed complete occlusion of the arteriovenous fistula. Two (18.2%) patients developed a bradycardia during DMSO injection. No complications related to the approach were observed.

Conclusions

Transvenous occlusion of cavernous DAVFs is a feasible approach, even via facial vein or via IPS. Onyx may be another option for cavernous packing other than detachable platinum coils.     

Bilateral dural arteriovenous fistula in the region of the cavernous sinus

Summary The case of a patient with a fistula between the left internal carotid artery and the cavernous sinus, and another fistula between the right external carotid artery and the cavernous sinus, is reported. The clinical symptomatology, which was of spontaneous onset, was unilateral and consisted of exophthalmos and injection of the conjunctiva on the left side. Almost complete remission occurred after angiography.     

Superior petrosal sinus catheterization for transvenous embolization of a dural carotid cavernous sinus fistula

We report the endovascular treatment of a dural carotid cavernous fistula in a 67-year-old woman in whom superior petrosal sinus catheterization was performed to access the venous site of the fistula. To our knowledge, this retrograde venous route via the superior petrosal sinus has not been previously described.     

Coil embolization of cavernous sinus in patients with direct and dural arteriovenous fistula

To determine technical success and acute complication rates after endovascular coil packing of the cavernous sinus. Nineteen patients presented with either direct (13) or dural (6) arteriovenous fistula (AVF) and were treated by means of coil embolization of the cavernous sinus. The aim of treatment was complete obliteration of the fistula. In a retrospective study, the degree of obliteration, regression of symptoms as well as complication rates were evaluated. Initial complete obliteration was achieved in 12 patients, subtotal occlusion of the sinus in 6 and incomplete packing with major residual fistula in 1 of the patients. Retreatment was successfully performed in two patients with early recurrence of AVF. Follow-up showed complete occlusion rates in 16 and subtotal obliteration in 3 patients. Chemosis and exophthalmus regressed rapidly in all affected patients. Persistence of cranial nerve deficits was observed in 11 cases. Postinterventional thrombosis of the ophthalmic vein was the only major acute complication (n = 2). Coil embolization of the cavernous sinus in cases with AVF is a complex procedure that is technically feasible and safe in the majority of cases. Adequate anticoagulation is recommended to avoid thrombembolic complications. Long-term outcome has to be determined by further studies.
