A RARE COMBINATION OF A CAROTID-SINUS CAV ERNOUS FISTULA AND SINUS THROMBOSIS - SUCCESSFUL THERAPY THROUGH ANTICOAGULATION

Dural carotid cavernous fistulas (DCCF) can be associated with venous thrombosis, We report on a rare case of a patient who developed a veno us infarct, which was diagnosed on CT and MRI. The DCCF predominantly drained through a frontobasal cortical vein into the superior sagittal sinus, The shunt volume was small and was therefore thought not to be sufficient to explain the massive ocular signs, such as severe exopht halmus and of visual acuity, We postulated a venous congestion owing t o a secondary spontaneous venous thrombosis of the draining venous pat hways to be responsible for the ocular signs, Under anticoagulative me dication, the patient's signs and symptoms improved gradually, Control angiography after 3 months showed that the DCCF had disappeared, In t he presence of DCCF, anticoagulation should always be considered when a venous thrombosis is suspected.
