| Popis: | Purpose Primary orbital varix is a rare lesion but difficult to treat. Our main aim was to demonstrate the varices and their central venous communication and to explore the feasibility of embolization of these lesions. Method In four patients with clinical suspicion of varix, in whom MRI showed retro-global vascular channels, microcatheter digital subtraction angiography (DSA) of the varices was performed using femoral venous access. Embolization was carried out in two patients. Results In all four patients orbital varices could be accessed with a microcatheter through inferior petrosal sinus and ophthalmic vein (superior or inferior) route. Microcatheter angiography showed opacification of varices and demonstrated their central venous communication. Two patients were treated with coil embolization. Complete resolution of symptoms was seen in one patient and partial relief in the other. Conclusion The study presents microcatheterization of orbital varices via the inferior petrosal sinus–cavernous sinus–ophthalmic vein route with injections into distal ophthalmic veins for demonstration of these variceal sacs and their central venous connection. Coiling to disconnect the venous communication should be the primary goal of embolization. |
