Abstract

Objective: To describe the direct percutaneous transorbital puncture technique for embolisation of the selected intraorbital and cavernous sinus dural arteriovenous fistula, which failed to be treated by conventional endovascular techniques. Methods: One case of intraorbital and five cases of cavernous sinus dural arteriovenous fistula were embolised through direct percutaneous transorbital puncture in 2012, and the clinical data were reviewed. Under fluoroscopic guidance with a three-dimensional (3D) skull reconstruction overlay, the cavernous sinus or ophthalmic vein was punctured via the superior orbital fissure. Then a microcatheter was inserted via the needle, and Onyx was injected to embolise the fistula with or without a combination of coils. Results: Complete obliteration of the fistula was achieved in all six patients. After operation all the patients experienced transient swelling of the punctured orbit persisting for three to five days. No other complications occurred. Follow-up of six patients at three to six months showed resolution of their initial neuro-ophthalmological symptoms in five and left visual loss in one did not recover. Six months follow-up angiogram showed no recurrence of these fistulas. Conclusion: Direct percutaneous transorbital puncture provides an option for the intraorbital and cavernous sinus dural arteriovenous fistulas, particularly when the conventional transvenous routes are inaccessible. Overlay of the 3D skull reconstruction can facilitate the precise puncture of the superior orbital fissure.
