Transvenous embolization of bilateral indirect carotid-cavernous fistulas via aunilateral transorbital approach.

Transvenous embolization of bilateral indirect carotid-cavernous fistulas via aunilateral transorbital approach. Orbit. 2020 Jun 19;:1-6 Authors: Laplant JF, Lim LH, Dumont AS, Nerva JD Abstract A 73-year-old man with a complex ophthalmologic history presented with several weeks of worsening diplopia, visual acuity, and proptosis bilaterally. Cerebral angiography demonstrated bilateral indirect Barrow type B carotid-cavernous fistulas (CCFs). Transarterial embolization was not attempted due to small arterial diameter and risk of stroke. Multiple attempts were made to access the fistula via a transfemoral venous approach and were unsuccessful. A transorbital puncture was performed, which allowed access to both cavernous sinuses via a unilateral approach. After embolization with Onyx, there was no residual fistula. The patient had a left-sided retrobulbar hematoma from the access. Right eye vision improved postoperatively. PMID: 32552143 [PubMed - as supplied by publisher]
