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.<\/jats:p>","DOI":"10.1136\/bcr-2015-011777","type":"journal-article","created":{"date-parts":[[2015,6,26]],"date-time":"2015-06-26T23:16:31Z","timestamp":1435360591000},"page":"bcr2015011777","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Transvenous sclerotherapy of a large symptomatic orbital venous varix using a microcatheter balloon and bleomycin"],"prefix":"10.1136","volume":"2015","author":[{"given":"Venu","family":"Vadlamudi","sequence":"first","affiliation":[{"name":"Department of Radiology, University of Michigan Health System, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph J","family":"Gemmete","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Michigan Health System, Ann Arbor, Michigan, USA"},{"name":"Department of Neurosurgery, University of Michigan Health System, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neeraj","family":"Chaudhary","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Michigan Health System, Ann Arbor, Michigan, USA"},{"name":"Department of Neurosurgery, University of Michigan Health System, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aditya S","family":"Pandey","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Michigan Health System, Ann Arbor, Michigan, USA"},{"name":"Department of Neurosurgery, University of Michigan Health System, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alon","family":"Kahana","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology and Visual Sciences, University of Michigan Health System, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,6,24]]},"reference":[{"key":"2025082702083418000_2015.jun24_1.bcr2015011777.1","doi-asserted-by":"crossref","unstructured":"Gunduz K , Karcioglu ZA .
