Superior ophthalmic vein thrombosis associated with severe facial trauma: a case report

INTRODUCTION Superior ophthalmic vein thrombosis is a rare entity, but is associated with significant morbidities. We describe a case in which superior ophthalmic vein thrombosis occurred shortly after severe facial trauma. CASE PRESENTATION A 77-year-old Japanese man was transferred to our tertiary hospital after a motor vehicle accident. Le Fort III facial bone fractures and a minor cerebral contusion were detected. Follow-up computed tomography scans detected dilatation of his left superior ophthalmic vein on day 3 and thrombosis on day 12; however, no causative carotid cavernous fistula was observed. As he did not present with any symptoms other than slight conjunctival congestion, a conservative management strategy was adopted along with anticoagulant therapy against deep venous thrombosis. The superior ophthalmic vein thrombosis resolved spontaneously and the conjunctival congestion also improved. CONCLUSIONS Superior ophthalmic vein thrombosis should be taken into consideration and managed properly after severe facial injuries, and further investigation of its cause is necessary to prevent morbidities.
