JUGULAR VENOUS OXYGEN MONITORING - A HELPFUL TECHNIQUE IN THE EARLY DIAGNOSIS OF A TRAUMATIC CAROTID-CAVERNOUS SINUS FISTULA

This report describes the early diagnosis of a right traumatic carotid -cavernous sinus fistula (CCSF) in a patient with head injury manifest ed as an acute increase in right jugular venous oxygen saturation and with no ophthalmic clinical signs. High values of jugular venous oxyge n saturation must be cautiously interpreted with the clinical examinat ion and computed tomographic findings to establish an accurate diagnos is of hyperemia with or without a CCSF.
