Carotid-cavernous sinus fistula associated with uncontrolled hypertension
Abstract
Introduction: carotid-cavernous fistula is the abnormal communication between the carotid arteries and the cavernous sinus that provokes variable ocular association. Case report: a 55-year-old male patient with a history of Down syndrome and chronic hypertension who spontaneously developed proptosis of the right eye and was referred to the neuro-ophthalmology clinic. After a meticulous ophthalmological examination and supported by neuro-imaging studies, a diagnosis of carotid-cavernous fistula of the right eye of low flow was reached. Conclusions: a patient with a low-flow carotid-cavernous fistula associated with poorly controlled hypertension was reported, an uncommon clinical condition that should be considered during the assessment of a patient with proptosis not associated with external trauma or surgery.
