Abstract
PURPOSE: To use color Doppler imaging in examining a patient with clinically diagnosed low-flow carotid-cavernous sinus fistula and a history of rheumatic heart disease. METHOD: The flow characteristics of the orbital vessels and the internal jugular veins were studied with a 7.0-MHz transducer. RESULTS: Episodic arterialization and reversal of blood flow was demonstrated in both superior ophthalmic veins. This similar waveform was also seen in both jugular veins. CONCLUSION: The presence of tricuspid regurgitation and pulmonary hypertension caused increased episcleral venous pressure and the corkscrew appearance, which is more commonly associated with carotid-cavernous sinus fistula.
