A 27-year-old female patient presented with headache, vomiting, and visual disturbances
who was evaluated and detected to have a direct carotid cavernous fistula (CCF). Secondary
causes were ruled out, and she was treated with coil occlusion and glue injection.
A month after almost complete clinical recovery, she developed deep vein thrombosis
of left thigh. Subsequent work-up revealed antithrombin III (ATIII) deficiency in
her. To the best of our knowledge, this is the first reported case of ATIII deficiency
associated with CCF. This case shows the importance of working up for a primary etiology
if any, to prevent further complications after surgery.
Key-words:
Antithrombin III deficiency - carotid cavernous fistula - deep vein thrombosis - sinus
thrombosis
