Role of Optic Nerve Fenestration as an Effective Salvage Therapy in Cerebral Venous Thrombosis: A Case Report and Review of Literature

Background: Cerebral venous thrombosis (CVT) is an uncommon, unrecognized type of stroke mostly affecting young people. Although a headache is the most common clinical manifestation of CVT, neurological focal signs like diplopia and papilledema are also frequently reported in the patients with such a problem. Currently, specific treatment for CVT involves anticoagulation or thrombolytic therapy. Case Report: In this report, we described a 13-year-old female, who was referred to our clinic with a headache and progressive loss of vision due to increased intracranial pressure. Along with usual anticoagulant therapy, we performed the optic nerve sheath fenestration (ONSF) to improve her vision. The patient visual acuity was improved, and after 11 months’ follow-up, no complication was detected.Conclusion: The ONSF can be safe and beneficial in patients with CVT and who are in immediate danger of visual deterioration despite being treated by other means.
