title: Transvenous sclerotherapy of a large symptomatic orbital venous varix using a microcatheter balloon and bleomycin.
abstract: An orbital venous varix is rare and can present with diplopia, proptosis, or hemorrhage. Treatment can be challenging, especially if the varix is in a posterior location within the orbit, since surgical exposure becomes difficult. A few case reports have been published describing transcatheter embolization of an orbital varix with coils, direct percutaneous injection of n-butyl cyanoacrylate glue, and the percutaneous injection of bleomycin. We present a case of a symptomatic orbital venous varix of the left inferior ophthalmic vein successfully treated with transvenous endovascular sclerotherapy using a microcatheter balloon and bleomycin.
